Fig. 3/10: Principle of error handling and parameterisation for CPX-P-8DE-N.. - part 3
The respective errors are registered or the message is sup-
pressed depending on parameterisation of the module. If
transmitted to the bus nodes, errors can be evaluated by
higher-level systems - depending on the bus protocol used.
The wire break monitoring and limit value monitoring func-
tions are inactive by default.
By using the module parameter “replacement value”, you can
specify whether the replacement value or the last signal
status is to be valid in a diagnostic case (
Tab. 3/28).
