2 Safety regulations and installation notes

2.1 Installation notes

The use of antennas with a gain greater than 6dBi may require that the transmit power be

reduced from the default setting of 30 dBm. Regulations limit the equivalent isotropically-ra-

diated power (EIRP) to 36dBm. The EIRP may be calculated as the transmit power (Pt)

minus any cable loss (Lc) plus the antenna gain (Ga).

For example, in the case of a 12dBi antenna used with a cable run with a 4dB loss, the

transmit power must be reduced to 28dBm or less such that the EIRP does not exceed

36dBm.

2.2 Installation and operation

Follow the installation instructions.

Error-free operation of this device can only be ensured if transport, storage, and assembly

are carried out correctly and operation and maintenance are carried out with care.

tional safety directives), accident prevention regulations, as well as general technical regu-

lations, must be observed.

Provide a switch/circuit breaker close to the device, which is labeled as the disconnect de-

vice for this device.

Please note that, in combination with antennas, the maximum permissible transmission

power may be exceeded. Please set the transmission power via the software.

 EIRP = Pt - Lc + Ga

The SATEL-LP-CONF configuration and diagnostic software can be used to configure the

transmit power.

ence, and (2) this device must accept any interference, including interference that may

cause undesired operation of the device.

To reduce potential radio interference to other users, the antenna type and its gain should

be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that

permitted for successful communication.

This device has been designed to operate with the antennas listed in this document and

having a maximum gain of 12dB. Antennas not included in this list or having a gain greater

than 12dB are strictly prohibited for use with this device. The required antenna impedance

is 50Ω.

Under Industry Canada regulations, this radio transmitter may only operate using an an-

tenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Can-

ada. To reduce potential radio interference to other users, the antenna type and its gain

3 Short description

Wireless communication is based on Trusted Wireless 2.0 technology. The requirement for

a high-quality interference-free data transmission is fulfilled by using, for example, the fre-

quency hopping method (FHSS) and 128-bit data encryption (AES). The SATEL-LP9 wire-

less system uses the license-free 900 MHz ISM band.

3.1 Wireless module

In addition to an RS-232 and RS-485 2-wire interface, the SATEL-LP9 wireless module

supports the option of directly connecting up to 32 I/O extension modules in the station

structure via the DIN rail connector.

Addressing of the wireless module and I/O mapping of the extension modules is carried out

quickly and easily by means of the thumbwheel on the front. You can use the yellow thumb-

wheel on the wireless module in order to set the RAD ID, and the white thumbwheel on the

extensions modules to set the I/O-MAP address. Programming knowledge is not required.

You can easily start up the wireless network without the need for software.

The SATEL-LP-CONF configuration and diagnostics software for special functions and di-

agnostics options in the wireless module is available free of charge.

Features

– Flexible network applications: I/O data, serial data, PLC/Modbus RTU mode

– Adjustable data rates for the wireless interface

– Easy point-to-point or network structures (star, mesh)

– Yellow thumbwheel for the unique addressing of wireless modules in the wireless net-

work

4.5 Connecting the power supply

Via screw terminal blocks

Connect a DC voltage source (10.8 V ... 30.5 V DC) to the wireless module. The nominal

voltage is 24 V DC. Supply voltage to the device via the terminals 1.1 (24 V) and 1.2 (0 V).

In the case of a connection station, it is sufficient to supply the first device in the group.

Figure 4-6 Connecting the power supply

In order to prevent damage to the wireless module, we recommend the installation of a

surge arrester. Wiring between the surge arrester and the wireless module should be as

short as possible. Please also observe the manufacturer’s specifications.

4.6 Serial interfaces

The SATEL-LP9 wireless module has one RS-232 interface and one RS-485 2-wire inter-

face. Connect the I/O device to the wireless module via the corresponding serial interface.

Both serial interfaces are deactivated by default. Activate and configure the RS-232 or

RS-485 interface using the SATEL-LP-CONF software (from page 34 onwards).

You can only use one interface per wireless module. Parallel operation of both interfaces

is not possible.

4.6.1 Shielding of the RS-485 bus cable

Connect the shield of the RS-485 bus cable correctly via an external shield connection

clamp.

Choose the type of shield connection depending on the interferences to be expected:

– Firstly, connect the shield on one side. This suppresses electrical fields.

– To suppress disturbances caused by alternating magnetic fields, connect the shield on

both sides. When doing so, the ground loops must be taken into account. Galvanic dis-

turbances along the reference potential can interfere with the useful signal, and the

shielding effect is reduced.

– If several devices are connected to a single bus, the shield must be connected to each

device (e.g., by means of clamps).

– Connect the bus shield to a central PE point using short, low-impedance connections

with a large surface area (e.g., by means of shield connection clamps).

4.6.2 Terminating the RS-485 bus cable

The SATEL-LP9 wireless module is operated on a 2-wire bus cable. RS-485 bus connec-

tions must be terminated at both ends with a 390/150/390  termination network.

Depending on the position of the device on the RS-485 bus cable, the termination network

must be activated or deactivated. The DIP switches 1 and 2 are located on the side of the

wireless module.

Table 4-1 DIP switches 1 and 2: termination network

NOTE: Damage to the interface

If the shield has been incorrectly connected, permanent, external disturbing pulses may

damage the interface.

Observe the polarity of the RS-485 2-wire cable and ensure that the shield is connected

correctly.

4.6.3 RS-485 pin assignment

In RS-485 mode, you can create a network with several I/O devices. Use a twisted pair bus

cable to connect the I/O devices. Fit this bus cable with a termination network at the two fur-

thest points.

• Connect the single wires of the data cable to the plug-in screw terminal block

(Figure 4-1, item 10).

• Make sure the signal assignment is correct.

Figure 4-7 RS-485 interface pin assignment

4.6.4 RS-232 pin assignment

In RS-232 mode, point-to-point connections can be established.

According to the standard, you can connect a DCE device (Data Communication Equip-

ment) to the RS-232 interface using a 1:1 cable (Figure 4-8). It is also possible to connect a

DTE device using a crossed cable (Figure 4-9).

Figure 4-8 RS-232 interface pin assignment (DTE - DCE)

Figure 4-9 RS-232 interface pin assignment (DTE - DTE)

The RS-232 interface of the wireless module is a DTE type (Data Terminal Equipment).

This means that terminal point 5.2 (Tx) is always used for transmission and terminal point

5.1 (Rx) is always used for reception.

Only connect the wireless module to devices which meet the requirements of EN 60950.

SATEL-LP9

SATEL 3594_en_B

If you are not sure whether the device to be connected is of DTE or DCE type, you can mea-

sure the voltage. Measure the voltage between Tx and GND in the idle state.

– If the voltage measures approximately -5 V, it is a DTE device.

– If the voltage measures approximately 0 V, it is a DCE device.

4.6.5 D-SUB 9 pin assignment

The SATEL-LP9 provides a D-SUB 9 female connector for attaching RS-232 serial devices.

You can connect the I/O extension modules to the controller directly via the integrated

RS-232 and RS-485 interface by means of wireless communication. In PLC/Modbus RTU

mode, the master wireless module (RAD ID = 01) operates as a Modbus slave. The master

wireless module has its own Modbus address.

You can connect I/O extension modules to each wireless module in the network. The

I/O data of the extension module is stored in the internal Modbus memory map of the master

wireless module. In addition, the diagnostic data from all wireless devices is stored here.

You need to configure each wireless module using the SATEL-LP-CONF software (from

page 34 onwards).

5.3 Setting the address of the wireless module via the

thumbwheel

Set the desired station address with the yellow thumbwheel on the wireless module. There

must be one master (RAD ID = 01) and at least one repeater/slave

(RAD ID = 02 ... 99) in a network.

The following settings can be made using the yellow thumbwheel:

Unique addressing is required in a network. If two wireless modules have the same ad-

dress in a network, the network will not function properly.

Setting the address via the thumbwheel has priority over setting the address via the

SATEL-LP-CONF software.

After making any change to the module address, press the SET button for one second to

apply the setting.

5.4 Configuration via SATEL-LP-CONF1 stick

By default upon delivery, all wireless modules have the same network ID and the same

RF band. Using a configuration memory (SATEL-LP-CONF1 stick), you can configure a

unique and secure network without the need for software.

The SATEL-LP-CONF1 stick is used as a network key. Its network address (network ID) is

unique and cannot be assigned via the SATEL-LP-CONF software. Only wireless modules

with the same network ID are allowed to connect with each other.

You have to configure each individual network device. To this end, you only need one

SATEL-LP-CONF1 stick for all wireless modules in the network. After configuration, you can

remove the SATEL-LP-CONF1 from the wireless module.

In addition, the SATEL-LP-CONF1 contains a preset frequency band (RF band). An RF

band is a group of frequencies compiled of individual frequencies of the entire 900 MHz

band. Different RF bands use different frequencies.

In order to operate several wireless systems, you should select different RF bands.

Figure 5-4 Configuration via SATEL-LP-CONF1

WARNING: Explosion hazard when used in potentially explosive areas

Do not insert or remove the SATEL-LP-CONF1 stick in a potentially explosive atmo-

sphere.

You can set different network IDs between 1 ... 127 by using the SATEL-LP-CONF soft-

ware (see page 35).

5.6.1 Extended configuration, individual settings

After reading an existing network project or creating a new project, the network settings can

be modified under “Individual Settings”. The wireless network can be optimized and

adapted to your special requirements. When moving the mouse over the individual network

parameters, you obtain a short description under “Help”.

Figure 5-5 SATEL-LP-CONF software: Network Settings

5.6.2 Data transmission speed of the wireless interface

The range is an important parameter in industrial wireless applications, especially in out-

door applications. Even in cases where long ranges do not have to be covered, good

receiver sensitivity enables transmission in harsh outdoor conditions, e.g., when there is no

direct line of sight.

The receiver sensitivity determines the signal amplitude which can just about be received

by the wireless module. The lower the data transmission speed of the wireless interface, the

higher the receiver sensitivity and thereby the range.

If several wireless systems are operated parallel and in close proximity, you are required

to set the RF band and the network ID. These parameters can be set via the SATEL-LP-

CONF software or by using a SATEL-LP-CONF1 stick (see “Configuration via SATEL-

LP-CONF1 stick” on page 32).

Adjust the data transmission speed of the wireless interface to the respective application

using the SATEL-LP-CONF software (default setting = 125 kbps).

In order to be able to cover the largest possible distances, the preamplifier has been ac-

tivated and transmission power set to 30 dBm by default. When operating the devices di-

rectly next to one another, the receiver might become overloaded. In this case, remove

the antennas, increase the distance between the devices and antennas or reduce trans-

mission power using the SATEL-LP-CONF software.

In order to be able to cover the greatest possible distances, the preamplifier has

been activated and transmission power set to 30 dBm by default. When operat-

ing the devices directly next to one another, the receiver might become overload-

ed. In this case, remove the antennas, increase the distance between the

devices and antennas or reduce transmission power using the SATEL-LP-CONF

software.

SET button

You can confirm a station change with the SET button, without performing a power up. Sta-

tion changes include:

– Changing the RAD ID address of the wireless module

– Changing the I/O-MAP address of the extension module

– Adding or remove an I/O extension module

– Using a SATEL-LP-CONF1 or memory stick

After making any change, press the SET button for at least one second to apply the settings.

The DAT LED starts flashing. Read in has been completed when the DAT LED stops flash-

ing.

RF link relay

The RF link relay in the wireless module diagnoses the state of the wireless connection. The

relay picks up when the wireless connection is established. If the wireless module does not

receive a data packet correctly over a period of 10 seconds, the relay drops out. The relay

picks up again automatically when the wireless connection is re-established.

The RF link relay has been designed as a PDT contact.

RSSI test socket

A voltage measuring device can be connected to the RSSI test socket to measure the RSSI

voltage between 0 V ... 3 V. The RSSI voltage depends on the data rate set for the wireless

interface. The higher the RSSI voltage, the better the wireless connection.

For example, the RSSI voltage may be helpful when positioning and aligning the antenna.

The recommended minimum signal strength is 2.0 V DC. This results in a power reserve of

approximately 10 dB which ensures communication even in the event of unfavorable trans-

mission conditions.

The RF link relay can be used as a fault message contact to indicate the failure of the wire-

less connection to the controller.

5.9 Starting up I/O extension modules

5.9.1 Combinations of extension modules

Several appropriate output modules at different stations can be assigned to one digital or

analog input module. The inputs are transmitted in parallel to the outputs. The channels of

the input module are mirrored to the channels of the output module.

Figure 5-18 Assignment of digital inputs and digital outputs

The combined SATEL-LP-DAIO6 extension modules can only be assigned in pairs,

because each module is provided with inputs and outputs. That is why only two modules in

the network may have the same I/O MAP address.

It is not possible to separately assign the individual input channels of an extension mod-

ule to different output modules.

5.10 Startup time of the wireless station

Once a wireless station has been started up (power “ON”), the wireless module will take

15 seconds to be ready for operation. Each linked I/O extension module increases the

startup time by 3 seconds.

Startup time of a wireless station =

15 seconds + (number of I/O modules x 3 seconds)

Accordingly, a complete wireless station with 32 I/O extension modules requires a startup

time of 111 seconds. Only after this period of time has elapsed is the wireless station ready

for operation.

In serial data mode, multiple controllers or serial I/O devices are networked quickly and eas-

ily using wireless technology. In this way, serial RS-232 or RS-485 cables can be replaced.

Figure 6-1 Serial data mode

You can configure the serial interface of the SATEL-LP9 wireless module using the SATEL-

LP-CONF software. In order to connect the wireless module to the PC, you need the

SATEL-LP-PROG cable (Order No. YC0520).

WARNING: Explosion hazard when used in potentially explosive areas

The USB cable must not be used in potentially explosive areas.

When operating the network in serial data mode, it may not be possible to diagnose all

devices. In this case, stop the serial application in order to allow for complete diagnostics.

Using the SATEL-LP-CONF software, you can assign different serial settings to the de-

vices under “Individual Settings”.

parameter refers to the minimum pause that must elapse between two frames

on the output side (wireless module is transmitting data via serial interface).

Figure 6-4 Frame-based data transmission: T

IdleMin

parameter

FrameEnd

parameter

FrameEnd

is the time which is kept by the transmitting wireless module between two frames.

If the data received by the wireless module is followed by a certain period of time where no

further data is received, the wireless module assumes that the frame has arrived in its en-

tirety. The frame is then transmitted. This period of time is referred to as T

FrameEnd

must be shorter than the minimum interval between two frames

FrameEnd

IdleMin

). T

FrameEnd

must, however, also be greater than the maximum interval

that is permitted between two characters in a frame. Otherwise the frame might be frag-

mented.

Setting telegram pauses, based on the example of Modbus/RTU

A frame is also referred to as a telegram. The length of the transmission pause between the

telegrams depends on the set data rate. The beginning and end of a telegram is recognized

by means of a time condition. A pause of 3.5 characters means that the telegram is com-

plete and the next character is to be interpreted as the slave address. A telegram must

therefore be sent as a continuous data flow. If there is an interruption of more than 1.5 char-

acters within a telegram, the data will be discarded by the receiver.

If the master is not able to transmit the successive characters quickly enough and the com-

munication is aborted, you must increase the minimum pause time (T

FrameEnd

) between the

individual characters of a telegram. Frames with a length of 1480 characters can be trans-

mitted by the SATEL-LP9 wireless system.

• In order to adapt data transmission to other protocols, it is possible to adapt the

FrameEnd

and T

IdleMin

parameters. Set the interface parameters under “Individual Set-

tings”.

1. Start the SATEL-LP-CONF software (see page 34).

2. Create a new network project.

3. Follow the software wizard.

Figure 7-2 SATEL-LP-CONF software: Wizard, Step 3

4. Select “PLC/Modbus RTU mode” and assign a Modbus address.

5. Follow the software wizard.

In order to enable the master wireless module to communicate with a controller via the

RS-232 or RS-485 interface, you are required to set the interface parameters. Please note

that the controller settings must match the settings of the wireless module.

Table 7-1 Configuration via SATEL-LP-CONF software

The Modbus connection between the controller and the wireless module can be monitored

via a watchdog. For additional information on the watchdog, refer to page 57.

The Modbus address is a unique address in the Modbus network. It is only assigned to

the master wireless module (RAD ID = 01). You can assign an address between 1 ... 247.

modules.

Use the white thumbwheel on the I/O extension module to set the I/O-MAP address. You

can find information on addressing extension modules from page 48 onwards.

7.3 Watchdog

The Modbus telegram watchdog monitors the connection between the master wireless

module and the controller. It is triggered each time a Modbus telegram is received correctly.

You can activate the watchdog using the SATEL-LP-CONF software.

• Select the “Network Settings” item under “Individual Settings”. You can set a watchdog

time between 200 ms ... 65,000 ms.

Figure 7-3 SATEL-LP-CONF software: Individual Settings, Network Settings

If the watchdog is triggered, an action will be performed on the I/O output modules. You can

set this behavior in the event of an error using the DIP switches on the front.

– OFF = RESET: Output value is set to 0

– ON = HOLD: Hold last output value

For more detailed information regarding switch setting for the different extension modules,

please refer to Section “Description of I/O extension modules” on page 75.

If the watchdog is activated and Modbus communication interrupted, the red ERR LED will

flash on all wireless modules in the network. Depending on the DIP switch settings, the out-

put modules issue the corresponding hold or reset value.

The data is transmitted using the Modbus/RTU (Remote Terminal Unit) protocol. Commu-

nication takes place according to the master/slave method. The Modbus master initiates

communication with a request to the slave. If the slave detects that its address has been ac-

cessed by the master, the slave always sends a response.

Only the master is able to initiate communication. The slaves are not able to initiate commu-

nication and do not communicate with each other.

The connected extension modules write the analog or digital input and output values to an

internal register. The Modbus master (e.g., a PLC) can read the individual registers using

the Modbus address of the slaves. The data to be transmitted is always included in a de-

fined frame. The frame is referred to as telegram.

The Modbus protocol defines the format of the telegrams. If an error occurs when the tele-

gram is received on the slave side, or if the slave is unable to carry out the master request,

an error telegram is sent back to the master.

Request from master

The function code in the request informs the addressed slave which action is to be carried

out. The address and data bytes contain all additional information that the slave requires in

order to carry out the action.

Example: The master uses function code 03 to request the slave to read the process output

data and send its content to the master. The data and address bytes need to include the fol-

lowing information: from which register reading should start and how many registers should

be read. Using the CRC check value, the slave is able to detect whether the complete tele-

gram has been received.

Response from slave

If the response from a slave is valid, the function code will match the request from the mas-

ter. The address and data field contains the data recorded by the slave (e.g., register val-

ues).

The function code is modified in the event of an error. The address and data field then con-

tains a code that describes the error. By using the CRC check value, the master is able to

determine whether the telegram content is valid or not.

The Modbus/RTU telegrams are separated by telegram pauses known as end-of-frame

times. The end-of-frame time must be at least 3.5 x as long as the time required for one

transmitted character. The end-of-frame time cannot be changed.

7.7 Module type and error code register

You can read the module type and data currentness of the I/O extension modules from the

registers 30xx0 and 40xx0.

Table 7-4 Module type and currentness of data

The individual I/O extension modules can be clearly distinguished by the module type. The

module type ID of the extension module can be read in the Modbus register.

Table 7-5 Module type IDs

“Module type” register value

If the module type in the register is invalid or unavailable, then the register value is 0.

“Currentness of data” register value

If the data in the register is not up-to-date, the register value is 1. This is, for example, the

case if the wireless connection to an input module fails. The input process data is then re-

tained in the Modbus table, but is no longer updated. In the case of an output module, the

“Currentness of data” register value is set to 1 until the output process data has been written

to the Modbus registers.

The read I/O data is only valid and current if a valid module type value is returned by the

slave and the “Currentness of data” register value equals 0.

7.7.1 Assigning I/O extension modules to the register

Use the white thumbwheel on the I/O extension module to assign an I/O-MAP address in the

Modbus memory map. Example: If you set the thumbwheel of an input module to the

I/O-MAP address = 01, the register assignment is 30010.

Table 7-6 Setting the white thumbwheel for register 30010 (read)

7.8 Modbus memory map

The I/O data from the extension modules is stored in an internal register, the Modbus mem-

ory map. The Modbus memory map is contained in the master wireless module with the

RAD ID = 01. The data contained here can be read or written by a Modbus master.

The following process data tables for the individual extension modules show at what posi-

tion the I/O data is stored in the Modbus memory map. You can find a complete overview of

the Modbus memory map from page 70 onwards.

The RSSI signal register can be found starting on page 74.

8.1 SATEL-LP-AI4 – Analog extension module with

four inputs

The analog SATEL-LP-AI4 I/O extension module can process up to four input signals be-

tween 0/4 mA ... 20 mA. All inputs are electrically isolated from one another, from the supply

voltage, and from the electronics.

A supply voltage of 12 V DC, minimum, is available at the PWR

connection terminal block

for passive sensors (see Figure 8-1, item 1).

8.2 SATEL-LP-PT100 – Extension module with four

temperature inputs

The analog SATEL-LP-PT100 I/O extension module has four Pt 100 inputs for temperatures

between -50°C ... +250°C. The Pt 100 inputs T1 ... T4 can be mapped to the analog outputs

I1/U1 ... I4/U4 of the SATEL-LP-AO4 extension module. All the inputs are electrically iso-

lated from one another, from the supply voltage, and from the remaining electronics.

Pt 100 resistance thermometers can be connected to the SATEL-LP-PT100 I/O extension

module. The thermometers change their resistance depending on the temperature. The

Pt 100 input signals are acquired by the SATEL-LP-PT100 and can be mapped to propor-

tional, analog voltage or current signals of the SATEL-LP-AO4 output module.

Example: At the Pt 100 input, a current of 0 mA or a voltage of 0 V is released at the output

module at a temperature of -50°C. At the Pt 100 input, a current of 20 mA or a voltage of 10 V

is released at the output at a temperature of 250°C.

8.2.1 Connecting sensors

You can connect 2-wire or 3-wire sensors to the extension module. Observe the measuring

errors depending on the different measuring methods.

2-wire connection technology

2-wire connection technology is the most cost-effective connection method. The tempera-

ture-related voltage is not directly measured at the sensor and therefore falsified by the two

cable resistances R

. The measuring errors that occur may lead to the entire measurement

to become useless. Please observe the diagrams in Section “Measuring errors using 2-wire

connection technology” on page 81.

With 2-wire technology, you need an insertion bridge between terminals x.2 and x.3.

Use the I/O extension modules in connection with the SATEL-LP9 wireless module, firm-

ware version 1.40 or later. You can update the firmware free of charge using the SATEL-

LP-CONF software, Version 2.04 or later.

The firmware and software can be found on the Internet at www.satel.com

Figure 8-5 2-wire connection technology

3-wire connection technology

With 3-wire connection technology, the temperature-related voltage is measured several

times. Corresponding calculations additionally reduce the effect of the cable resistance on

the measurement result. The results are almost as good as those achieved using the 4-wire

technology.

The cable resistances R

at the terminals +I and -I must have the same value. This allows

you to subtract the established cable resistance from the measurement result and to get the

Pt 100 platinum resistance value.

4-wire connection technology

The SATEL-LP-PT100 does not support the 4-wire connection technology.

• If you want to use a 4-wire sensor, only connect three of the four wires.

• The fourth wire should be left unwired. Otherwise there will be a different resistance in

the +I and -I cables owing to the parallel connection of two cable resistances.

Make sure that the cable resistance and therefore the measuring error is as low as possible.

• Use sensor cables that are as short as possible.

• Avoid conductor cross sections smaller than 0.5 mm

The temperature has only a small influence on the cable resistance.

You can calculate the cable resistance as follows:

Due to there being two cable resistances in the measuring system, the value must be dou-

bled. Using the average temperature coefficient α = 0.385 Ω/K for Pt 100, the absolute mea-

suring error in Kelvin can be determined for platinum sensors according to DIN standards.

8.2.3 Shielding of the sensor cables

Always connect the analog sensors using shielded, twisted pair cables (e.g., LiYCY, TP

2x2x0.5mm

• Immediately following entry in the control cabinet, connect the cable shields to the cor-

responding shield connection clamps.

Figure 8-11 Shielding with 3-wire connection technology

2-wire connection technology with twisted pair cables and shielding

Figure 8-12 2-wire connection technology with twisted pair cables and shielding

Please note that the electrical isolation between the channels may no longer occur when

connecting the shields. The isolating distances between the individual channels need to

be re-evaluated after connecting the shields. The distances between the individual wires

and the common shields are crucial in this respect.

manually reset the counter states in three different ways:

Reset counter state via power up

• Disconnect the device power supply and then reconnect the voltage.

Reset counter state via the Modbus RTU register

• Reset the counter states via Modbus RTU as follows:

– DI1: bit 0 = 1 (register 40xx1)

– DI7: bit 1 = 1 (register 40xx1)

Reset counter state by setting the inputs

• Set the corresponding input for at least 0.5 seconds:

– Set the DI3 input in order to reset the DI1 counter state.

– Set the DI5 input in order to reset the DI7 counter state.

nals that are switched via transistor outputs. The eight outputs are arranged in two groups

of four outputs each with a common electrical supply. The two output groups are electrically

isolated from one another, from the supply voltage, and from the electronics.

Since the DO1 ... DO4 and DO5 ... DO8 output groups are electrically isolated, the digital

outputs must be externally supplied (see Figure 8-33).

• The DO1 ... DO4 outputs are supplied via:

– Terminal 1.1 (12 V DC ... 30.5 V DC)

– Terminals 1.2/1.3 (GND)

• The DO5 ... DO8 outputs are supplied via:

– Terminal 6.1 (12 V DC ... 30.5 V DC)

– Terminals 6.2/6.3 (GND)

Use the I/O extension modules in connection with the SATEL-LP9 wireless module, firm-

ware version 1.40 or later. You can update the firmware free of charge using the SATEL-

9 Planning wireless systems

9.1 Trusted Wireless 2.0

Trusted Wireless 2.0 technology is specifically for industrial applications and operates in the

license-free 900 MHz frequency band.

Features

– Rugged communication via the frequency hopping spread spectrum (FHSS)

– Automatic and manual mechanisms for coexistence with other systems transmitting in

the same frequency band

– Secure data encryption and authentication

– Long range thanks to high receiver sensitivity and variable data transmission speed

– Flexible network structure with automatic connection management

– Distributed network management

– Comprehensive diagnostics options

– Adaptations to the required application are possible

Frequency hopping spread spectrum (FHSS) method

In the license-free 900 MHz frequency band, Trusted Wireless 2.0 uses the FHSS method.

This method uses a selection of up to 127 channels from the entire spectrum of the fre-

quency band. The wireless module “hops” between these channels on the basis of a

pseudo-random pattern. This leads to a more robust and more reliable communication.

Coexistence management

Black listing means that certain frequencies can be hidden selectively. For example, this

method allows you to operate several 900 MHz systems in parallel to Trusted Wireless 2.0

systems without any performance limitations.

Data encryption and authentication

Trusted Wireless 2.0 is a proprietary technology. The protocol has not been published.

Therefore it is better protected against attacks. In addition, two security mechanisms have

been implemented with 128-bit AES data encryption and authentication. The data encryp-

tion makes sure that intercepted data packets are not “understood”. The authentication pro-

cess checks the sender’s authenticity. For this, a continuous code is added to the message,

which must not be repeated. A manipulated message will be recognized as not valid and

discarded.

SATEL-LP9

116

SATEL 3594_en_B

Range

You can set the data rate of the wireless interface and adapt it to the respective application

(16 kbps ... 500 kbps). By reducing the data rate, you can increase the sensitivity of the re-

ceiver and therefore the range. Distances from a few hundred meters to several kilometers

can be covered using Trusted Wireless 2.0.

Network structures

Wireless modules can be used to create network structures with up to 250 devices. In this

case, each device has a repeater function for forwarding data. In addition, the Trusted Wire-

less network is able to self-heal connection aborts (self-healing network). Alternative con-

nection paths are initiated automatically. From a simple point-to-point connection to com-

plex mesh networks, you can flexibly create various structures.

Figure 9-1 Point-to-point connection, star network, self-healing mesh network

Distributed network management

Technologies such as WirelessHART or ZigBee use a central network management. That

means that all messages pass through a central manager, which can lead to significant vol-

ume of wireless network traffic.

Trusted Wireless 2.0, however, uses a distributed network management. For this purpose,

“parent-child zones” are created in the wireless network, where the higher-level wireless

module is referred to as the “parent” and the modules connected to it as “children”. All net-

work management takes place within the parent-child zone and does not have to be di-

rected through a central manager. This reduces the message traffic volume and accelerates

the data exchange.

Planning wireless systems

Figure 9-2 Distributed network management with parent-child zones

9.2 Planning wireless paths

When planning wireless paths over large distances, you need to consider height variations.

A topographic map or a GPS device are very helpful in this regard. Using GPS devices, you

can indicate variations in height and measure distances by means of way points. You can

use the GPS devices as a direction indicator when later aligning the antennas.

Theoretical planning

The following questions should be taken into account when doing the theoretical planning:

– Which signals are to be transmitted?

– What points are the signals to be transmitted between?

– What is the distance between these points?

– Are there any topographic or structural obstacles?

– Are you able to circumnavigate these obstacles, e.g., by means of a repeater of higher

mast?

When evaluating the data, you can carry out a system calculation to determine whether the

wireless path is theoretically possible. You can find a calculation example from page 125

onwards.

9.3 Practical test

To check the theoretical results, you should carry out an on-site practical test before pur-

chasing a wireless system. Check the location for master, slave and repeater/slave mod-

ules on the basis of the following criteria in order to achieve the optimum wireless connec-

tion:

– Antenna is positioned ensuring a line of sight and a sufficient signal strength

– Primary power source for energy supply is available

– Protection of wireless modules against any influences of weather and extreme ambient

conditions

– Adequate connections for antenna, surge protection, interface and other required ca-

bles

These requirements can be quickly assessed in most applications. However, it is often dif-

ficult to position the antenna. Of course, a connection path without any obstacles would be

perfect. However, small obstacles in the Fresnel zone will not necessarily disturb commu-

nication. In general, obstacles on long wireless paths have a greater influence than on short

ones.

9.4 Selecting antenna cables and antennas

Antenna cable

When installing a wireless system, it is very important that you use low-loss coaxial cables.

Using an unsuitable cable may lead to considerable loss in performance which can neither

be compensated by a high antenna gain nor by a high transmission power. For every 3 dB

of coaxial cable loss, half the transmitter power will be lost before reaching the antenna. The

received signal will also be reduced.

Consider the following factors when selecting the cable:

– Cable length to the antenna

– Acceptable signal loss

– Cable installation options

Antenna

Select the antenna depending on the application:

Application Antenna

Short range and direct line of sight without

any obstacles

Small omnidirectional antenna

Medium range Large omnidirectional antenna (observe

the vertical apex angle)

Wide range Panel antenna (observe the horizontal apex

angle)

Planning wireless systems

3594_en_B SATEL 119

9.5 Installing antennas

The following recommendations apply to all antenna installations:

Install the antenna in an open area as far away as possible from any obstacles such as

buildings, dense deciduous forest or metal objects. Choose a location that provides a clear

signal path in the direction of the opposite antenna. If two antennas are located in the same

place, they should have a distance between them of at least 0.6 m in the vertical direction

and 1 m in the horizontal direction.

Pay attention to antenna polarization. Most systems use a vertically polarized omnidirec-

tional antenna at the master station. The opposite antennas must therefore also be polar-

ized vertically. Vertical polarization means that the elements are aligned vertically to the

horizon. Crossing polarization between the stations results in a signal loss of 20 dB, mini-

mum.

Figure 9-3 Antenna polarization

WARNING: Explosion hazard when used in potentially explosive areas

Observe the safety notes in “Safety regulations and installation notes” on page 11.

9.5.1 Aligning directional antennas

• First, align the antennas roughly. Use the following:

–Topographic map

– GPS device or compass

– LED bar graph on the wireless module

Even if there is no direct line of sight, you can find the alignment point:

• Having carried out a rough alignment, you can now finely align the antenna via the RSSI

voltage. Measure the RSSI voltage at the RSSI test socket of the wireless module

(2.1/2.2) using a multimeter. For additional information on the RSSI voltage, please re-

fer to page 42.

• You always have to align both antennas with each other, because the radio waves need

to radiate into the antennas.

• In particular with regard to directional antennas, it is important to ensure that the anten-

na is properly fixed. If the antenna sways in the wind, the transmission or reception

beam can move out of its target area.

9.6 Propagation of radio waves

In addition to the free space path loss, there are other factors which influence the wireless

path. Dispersion, diffraction, and reflection represent types of interference that occur when

the wireless signal encounters obstacles. They result in multipath propagation.

Dispersion

The dispersion of the wireless signal (e.g., at a tree) means that the wireless signal is dis-

persed in several directions. A tree without any leaves virtually allows all signals to com-

pletely pass through, whereas a tree with foliage results in a considerable degree of disper-

sion. The leaf surfaces disperse the wireless signal in all possible directions.

Figure 9-4 Dispersion on a rough surface

Diffraction

Diffraction of the wireless signal, e.g., on edges and obstacles, involves the signal being re-

fracted around the edge. The signal then changes its direction. This is similar to the refrac-

tion of light in a crystal.

Planning wireless systems

3594_en_B SATEL 121

Figure 9-5 Diffraction on an edge

Reflection

Reflection on a smooth metal surface involves virtually the entire wireless signal being re-

flected at the same angle. In certain applications, the reflection may have a positive effect

(e.g., if there is no line of sight). Reflections mainly occur in buildings.

Figure 9-6 Reflection on a metal surface

Penetration

The type of wall encountered also influences the attenuation of the wireless signal. For ex-

ample, the following constructions adversely affect the wireless signal:

– Hollow lightweight walls with aluminum-lined insulation

– False ceilings with metal or carbon fiber panels

–Lead glass

– Insulation glass (Thermopen)

– Glass with a metal coating

– Steel objects

– Fire walls

– Elevator shafts and stairwells

Each material has a different degree of attenuation. However, the following typical values

provide a rough orientation.

Figure 9-7 Reduction of radio waves when penetrating a wall

Also observe the angle between transmitter and receiver. Depending on the angle, the radio

waves have to penetrate more or less material.

Figure 9-8 Angle of the transmitter and receiver

Radio dead spot

Radio dead spots are caused by impenetrable obstacles in the wireless path. The radio

dead spot can be compared to the shadow cast by the sun. If the receiver is located in a

radio dead spot, no direct radio waves can reach it, it can only receive reflections or dif-

fracted waves.

Weather influences

Snow, rain or hail have no effect on the wireless signal in the 900 MHz range.

A strong wind does not influence the wireless signal, however, it places high requirements

on the secure fixing of the antenna. In particular when using panel antennas with a small

apex angle, you should ensure that the antenna cannot be shifted by the wind. If the antenna

is moved by just 1 cm from its original position, this can result in a partial loss of the wireless

signal, especially when it has a long transmission path.

9.7 Fresnel zone

A certain area between the transmitting and receiving antennas on the wireless path is re-

ferred to as the Fresnel zone. There should be a line of sight, especially in the event of lon-

ger distances, between the antennas. To adhere to the Fresnel zone, you might be required

to install the antennas at a height of a few meters. This area should also be free from

any other obstacles.

The ideal wireless path with a direct line of sight between transmitter and receiver is not al-

ways possible. In applications, obstacles often have to be taken into consideration, which

affect the wireless channel. The wireless path may also work if obstacles (house, tree, etc.)

are within the Fresnel zone. The decisive factor is the number of obstacles and the area they

occupy in the Fresnel zone. In this case, you should carry out test measurements.

Inside buildings, e.g., in conventional automation environments, there is a predominance of

reflections. They contribute to a good wireless connection even if the Fresnel zone is not

free from obstacles.

The following figure shows the Fresnel zone between two antennas. The required mounting

height for the antennas depends on the radius of the Fresnel zone.

Figure 9-11 Fresnel zone

Table 9-2 Radius of the Fresnel zone depending on the distance

General formula for calculating the diameter of the Fresnel zone:

r = radius of the Fresnel zone

Planning wireless systems

3594_en_B SATEL 125

Radius of the Fresnel zone with d = 3000 m:

r = 15.68 m

Result: The radius of the Fresnel zone is 15.68 m at a wavelength of 0.328 m (900 MHz) and

a distance of 3000 m between the antennas.

9.8 Equivalent isotropically radiated power (EIRP)

The equivalent isotropically radiated power is a gauge of the radiation power of an antenna.

The EIRP value is the sum of the transmission power in dBm and the antenna gain in dBi.

Example:

–Transmission power = 30dBm

–Antenna gain = 2dBi

– Attenuation through a 3 m long cable = 2.85 dB

– EIRP = 30 + 2 - 2.85 dBm = 29.15 dBm

– Wireless path length: 400 m

(30 dBm must not be exceeded for legal reasons, adapt the cable, adapter or transmis-

- free space path loss [dB]

+ gain of the receiving antenna [dBi]

- attenuation of the antenna cable at the receiver [dBm]

System reserve =

receiver sensitivity [dBm]

- incoming power for the receiver [dBm]

(recommended system reserve >10 dB)

EIRP = 29.15 dBm

Free space path loss [dB] =

32.4 + 20 log(f[MHz]) + 20 log(R[km]) = 32.4 + 20 log(900) + 20 log(0.4) = 83.5 dB

Incoming power for the receiver = -55.2 dBm

Receiver sensitivity = -105 dB (with a data rate of 125 kbps)

System reserve = 105 dB - 55.2 dB = 49.8 dB

Conclusion: The losses of 55.2 dB are significantly lower than the receiver sensitivity of

-105 dB. The desired wireless connection is therefore possible in mathematical terms.

Detecting and removing errors

3594_en_B SATEL 127

10 Detecting and removing errors

If your wireless system does not function properly, proceed as follows:

• First, ensure that you have a good wireless signal (2 green bar graph LEDs or RSSI

voltage ≥1.5 V).

• Check the status of the individual stations:

– If the SATEL-LP-CONF software is installed, check the device status of all network

devices via online diagnostics.

– If the SATEL-LP-CONF software has not been installed, check the bar graph LEDs

on the front of each device.

• Find the error using the tables from page 128 onwards.

Strength of the receive signal

You can determine the strength of the receive signal by means of the RSSI voltage. The sig-

nal strength is displayed on the LED bar graph on the wireless module.

– In a point-to-point connection, the LED bar graph is active on the master and on the re-

peater/slave.

– In a wireless network with more than one repeater/slave, only the yellow LED on the

master is permanently on. The signal strength is displayed on the repeaters/slaves. The

displayed signal strength is always related to the next wireless module in direction of

the master (parents).

The RSSI indicator is a voltage output in the range between 0 V DC ... 3 V DC. The higher

the voltage, the better the wireless connection. The measured voltage is directly related to

the receive signal in -dB. However, please observe the small voltage fluctuation due to mul-

tipath propagation.

The recommended minimum signal strength is 1.5 V DC. This results in a power reserve of

approximately 10 dB which ensures communication even in the event of unfavorable trans-

mission conditions.

You can measure the RSSI voltage at the RSSI test socket or read it using the SATEL-LP-

CONF software. When connecting the master wireless module to a PC, you can read the

RSSI voltages in the entire wireless network. At a slave or repeater, it is only possible to read

the RSSI voltage of the specific wireless module connected.

Table 10-1 RSSI voltage

Avoid contact between the antennas of two wireless module, otherwise the receiver might

become overloaded.

Ground loops are caused by the grounding of the antenna via the antenna fixing unit,

grounding the power supply or serial interface. To avoid ground loops, connect these

components to a single ground point.

10.1 Loopback test during serial data transmission

With an RS-232 interface, you can use the loopback test to check the data path from the

master to the slave and back again. To this end, you need to short-circuit two terminal points

of the RS-232 interface on the slave wireless module. It is then possible to transmit charac-

ters to the master wireless module using a terminal program (e.g., HyperTerminal). The

characters are echoed back to the terminal program.

To carry out a loopback test, proceed as follows:

• Close all PC programs on your PC, including the SATEL-LP-CONF software.

• Connect the PC to the master wireless module and start HyperTerminal via

“Start, All Programs, Accessories, Communication, HyperTerminal”. The COM port set-

tings on the PC must correspond to the interface settings on the master wireless mod-

ule.

• Connect the terminal points 5.1 and 5.2 of the RS-232 interface on the slave module

you need to test.

Figure 10-1 Loopback test for an RS-232 interface

• Connect both wireless modules to the power supply.

• Check the wireless connection via the LED bar graph.

Note for Windows 7 users:

HyperTerminal is no longer available in Windows 7. Instead you can use any other termi-

nal program.

• Enter several characters of your choice. HyperTerminal transmits these characters

over the wireless path. On the slave side the characters are output (e.g., at terminal

point 5.1, RX cable of the RS-232 interface) and immediately read again using the

bridge (e.g., at terminal point 5.2, TX cable of the RS-232 interface). This returns the

already transmitted characters and they appear twice on the HyperTerminal screen.

– The screen remains blank if the check was not successful. Monitor the TX and RX

LEDs on every wireless module. You can thereby determine the point up to which

data has been transmitted.

– In case the characters only appear once, check the HyperTerminal settings for hid-

den outgoing characters. The following options must be enabled under

“File, Properties, Settings, ASCII Setup”:

“Echo typed characters locally” and

“Append line feeds to incoming line ends”

A 1 Configuring a PROFIBUS connection

In order to configure a point-to-point or star connection for PROFIBUS transmission, pro-

ceed as follows:

• Download the latest SATEL-LP-CONF software from the Internet at

www.satel.com

• Install the software on your computer.

• Use the SATEL-LP-PROG cable (Order No. YC0520) to connect the wireless module

to the PC.

Configuring the connection

• Start the SATEL-LP-CONF software.

• In the “Wireless” folder, select the device.

Figure A-1 SATEL-LP-CONF software: Device Selection

WARNING: Explosion hazard when used in potentially explosive areas

The USB cable must not be used in potentially explosive areas.

SATEL 3594_en_B

• Select “Create new network project”.

Figure A-2 SATEL-LP-CONF software: Network Project

• In step 1 of the wizard, select “Point to Point/Star” and confirm with “Next”.

Figure A-3 SATEL-LP-CONF software: Wizard, Step 1

Configuring a PROFIBUS connection

3594_en_B SATEL 137

• Follow the software wizard. Specify the number of network devices. Confirm with “OK”

and “Next”.

Figure A-4 SATEL-LP-CONF software: Wizard, Step 2

• In step 3, select the “Serial data” network application. Configure the network settings:

–RF band

– Network ID

– Optional: showing/hiding WLAN channels

• Depending on the distance between the wireless modules, you can set the desired data

rate under “Network speed/distance relation”.

You can achieve transmission within the kilometer range using the wireless module if the fol-

lowing conditions are fulfilled:

– Suitable gain antennas are used

– Line of sight

– Adherence to the Fresnel zone

• Then confirm with “Next”.

Figure A-5 SATEL-LP-CONF software: Wizard, Step 3

SATEL 3594_en_B

• In step 4, select the PROFIBUS connection profile and set the desired data rate. De-

pending on the distance to be covered, reduce the serial data rate (wireless interface

125 kbps or 250 kbps), if required. Confirm with “Next”.

Figure A-6 SATEL-LP-CONF software: Wizard, Step 4

• In step 5, you will see an overview of the settings that have already been made. Check

these settings and confirm with “Next”.

Figure A-7 SATEL-LP-CONF software: Wizard, Step 5

Owing to the increased delay time, PROFIBUS transmission with 16 kbps is not possible.

Configuring a PROFIBUS connection

3594_en_B SATEL 139

• Save the project in step 6.

Figure A-8 SATEL-LP-CONF software: Wizard, Step 6

• Open “Individual Settings” and set “Transmissions” to 1. Save the settings again and

click “Transfer” to transfer them to the devices.

Figure A-9 SATEL-LP-CONF software: Network Settings

Connecting the PROFIBUS cable

• Connect the PROFIBUS cable to both wireless modules:

– Negative data wire (green) to terminal D(A) 4.1

– Positive data wire (red) to wire D(B) 4.2

• Activate bus termination if the wireless module is located at the start or the end of the

electrical PROFIBUS segment. To do so, set the DIP switches 1 and 2 to ON. The DIP

switches are located on the side of the wireless module.

SATEL-LP9

SATEL 3594_en_B

Configuring the PROFIBUS master

• Adjust timing in the PROFIBUS master to the signal runtime over the wireless path.

This setting is shown here using the SIMATIC Manager, Version 5.x as an example:

The wireless modules do not modify the PROFIBUS telegram (transparent transmission,

“Tunneling”). They only modify the PROFIBUS cycle time. In the case of an optimal wireless

connection, the wireless modules will cause a delay time of approximately 50 ms, unidirec-

tionally approximately 25 ms.

If the wireless component is connected in series with other components, then the delay time

of each component needs to be added together. Remember to take into account long ca-

bles, repeaters, fiber optics, other wireless components, etc.

The additional delay time may increase in the event of a poor wireless connection. Alterna-

tively, the connection may be terminated completely. In the case of a bad connection, the

wireless module will not discard PROFIBUS telegrams but try to repeatedly transmit them.

• For the wireless connection, consider the following PROFIBUS situations:

– In the PROFIBUS master - minimum delay time of 50 ms

Tslot_Init parameter (maximum wait time for receipt)

– In the ROFIBUS master - short interruption of the wireless connection

Retry-Limit parameter (maximum number of connection retries)

– In the PROFIBUS slave - permanent interruption of the wireless connection

Watchdog time parameter

– Telegram size: 40 bytes user data, maximum

• You have two options for setting the Tslot_Init parameter (maximum wait time for re-

ceipt):

– Automatically - Enter the number of repeaters and the cable length under “Op-

tions, Cables”.

– Manually - Directly enter the bus parameters under “User-defined, Bus Parame-

ters”. In this case, deactivate the automatic calculation, otherwise the sum of the

automatic and manual entry will be used.

We recommend that you use the manual entry:

– Entry: Tslot_Init > 13000 t_bit

– Entry: Retry-Limit > 3

–Recalculate

– Entry: Watchdog time, depending on the application

In certain circumstances, it may be required that the Tslot_Init value is greater than

13000 t_bit. For example, this may occur, if there is a poor wireless connection or the com-

ponents are connected in series. The value of 50 ms will increase by the factor x.

Configuring a PROFIBUS connection

3594_en_B SATEL 141

The Tslot_Init parameter is expressed in t_bit. The maximum value for a Siemens S7 PLC

is 16383 t_bit (S5: 9999 t_bit). The maximum wait time for receipt is therefore 93.75 kbps =

174 ms. In this case, the value 13000 t_bit is the minimum delay time of the wireless module

+ reserve.

• Start the SIMATIC Manager and open you user project. Select “Extras, Configure net-

work” from the pull-down menu.

Figure A-10 SIMATIC Manager

• In the “NetPro” window, right-click the PROFIBUS line. In the context menu, open

“Object Properties”.

Figure A-11 “NetPro” window

• In the “Network Settings” tab, select the transmission speed of 93.75 kbps.

• Click “Options”.

• In the “Cables” tab, deactivate the “Take into account the following cable configuration”

option. Confirm with “OK”.

Figure A-13 “Cables” tab

• In the “Network Settings” tab, select the “User-Defined” profile and the “Bus Parame-

ters” option.

Figure A-14 “Network Settings” tab, Profile

• In the “Bus Parameters” tab, the most recently valid bus parameters are shown. Enter

the following values:

The value for the Tslot time and the telegram runtime of PROFIBUS depend on your ap-

plication. Start with 13000 t_bit in order to achieve the smallest possible telegram runtime.

Increase the value if bus errors occur.

• Recalculating the bus parameters also modifies the watchdog value. Enter 93750 t_bit

here to achieve a watchdog time of 1 second for the PROFIBUS slave. Confirm with

“OK”.

PROFIBUS controller in DP slave mode

You can change the operating mode of the PROFIBUS controller under “Properties - DP”.

The DP controller can be operated as a master or slave.

To ensure error-free operation, the “Test, commissioning, routing” box must not be en-

abled. If this option is activated, the interface becomes an active PROFIBUS device and

takes part in the token rotation of PROFIBUS.
