Configuration of the cyclic data telegram
Use the configuration software of your PLC in order to compose the data telegram from
these modules in one of the following ways:
1. Main value
In order to transmit the main measured value, selct the module Main Process Value.
2. Main value and second cyclic value
In order to transmit the main value and the second cyclic value (temperature or
measured distance), select the modules in the following order: "Main Process
Value", "2nd Cyclic Value", "FREE PLACE".
3. Main value and display value
In order to transmitt the main value and to receive a display value select the modules
in the following order: "Main Process Value", "FREE PLACE", "Display Value".
4. Main value, second cyclic value and display value
In order to transmit the main value and the second cyclic value and to receive a dis-
play value, select the modules in the following order: "Main Process Value", "2nd
Cyclic Value", "Display Value".
The exact way of performing the configuration depends on the configuration software
of the PLC.
