S100 PROFInet Option Manual
12 Processing the Alarms
The S100 communication module sends a PROFInet alarm notification to the PLC
when a fault trip occurs, or when it is released.
Fault Alarm Packet Details
After a fault alarm is received, the PLC has to read the inverter trip parameters to
collect detailed information about the fault trip, such as the fault trip type (latch type
trip-1, latch type trip-2, level type trip, or H/W diagnosis trip).
