CODESYS RevPi Mapping Values


  • RS485ErrorLimit1: 10
  • RS485ErrorLimit2: 1000

If the standard values shall be modified, you have to assign the values in the corresponding POU.

Note on the RevPi IO Cycle

The overall cycle time is typically around 5 ms to 10 ms depending on the system configuration but could be longer for a large configuration.
This is the time it takes for a change in input or output to be realized in the memory of the RevPi controller. This happens using a background process that polls the modules to read values and writes to them when a change in the local device file is detected.
