7Process data
You can read or write the process data via the serial
interface of the master wireless module (RAD ID=01) using
Modbus RTU commands.
With the SATEL-LP-CONF software, you can set the
wireless module's network application to “PLC/Modbus
RTU mode”.
xx=I/O MAP address set using the white thumbwheel
7.1 Functions in pulse counter mode
Reset counter state via Modbus/RTU
• Reset the counter states via Modbus/RTU as follows:
DI1: bit0=1 (register 40xx1)
DI7: bit1=1 (register 40xx1)

Register values:
Module type If the module type in the register is invalid
or unavailable, then the register value is0
Currentness of
data
Y = Currentness of data, bit8
If the data in the register is not up-to-date,
then the register value is1.
This is the case, forexample, if the
wireless connection or communication
with an input module fails. In this case, the
IN process data is retained in the Modbus
table, but is no longer updated.
