7.7 Alarm and Error Messages of LioN-P/-R
Modules via PROFINET
Attention:
Alarm and error messages are only transmitted via
PROFINET when the parameter for diagnostics is activated in the
configuration of the modules in the controller.
If the LioN-P modules detect an error condition, an alarm message will be
triggered. The modules support diagnostic alarms. Diagnostic alarms are
triggered in case of peripheral faults such as overload, short-circuit, and
undervoltage.
An alarm is triggered in case of an incoming event (such as sensor short-
circuit) as well as an outgoing event.
The evaluation of the alarms depends on the PROFINET I/O controller used.
