4.10 L_IOParCompactModule − Parameterisation function

This function block assists in the setting of parameters relevant to PLC control compact module

communication.

· Parameterising a function for process data exchange time monitoring.

· Output nState indicates the parameterisation process status.

· Use output DataTo_IODataBlockModule to transfer fixed−structure information to process data

block L_IOCompactModule.

byNodeAdr Byte Device address: 1 − 63

bInitIOSystem Bool Initialise I/O system after parameterisation

TRUE · Value accepted via Reset Node

· I/O system is reinitialised, status changes to OPERATIONAL

FALSE · No value accepted

· I/O system is not initialised

byErrorBehavior Byte Set the bus states

tTimeOutPDO1_DataToIO Time Monitoring period for process input data (Lenze−specific).

If no data are received at the selected PDO within the monitoring period, the I/O

system assumes the state set under byErrorBehavior.

Default t = 0 ms (monitoring off)

t = 0 − 65535 ms

tTimeOutPDO1_DataFromIO Time Monitoring period for process output data.

If no data are transmitted from the I/O system to the PLC at the selected PDO within

the monitoring period, function block l_IODataXXX signals a time monitoring error.

Default t = 0 ms (monitoring off)

t = 0 − 65535 ms
