Process output data - counter mode
The process output data is the data that is output from the PLC via the gateway to the
XN-1CNT-24VDC module.
The XI/ON module allows some parameters to be modified during operation.
The other parameters must be changed prior to commissioning.
The data is transferred in 8 byte format:
• Four bytes provide the parameter values for "Load direct", "Load in preparation", "Reference
value 1", "Reference value 2" or "Behavior of the digital outputs".
• Two control bytes contain the control functions for transferring the parameter values, for
starting/stopping the measurement, for acknowledging errors and for resetting the status
bit.
Note
The current count operation is stopped if parameters are changed during operation.
Note
The parameters modified via the process output data are not retentive. The commis-
sioning after a power failure is based on the parameter data of the configuration tool
or default configuration.
