Alarm Management
A IO-device is able to send alarms to the IO-controller. When a alarm is received, the IO-controller is
expected to get the alarm description, then to acknowledge the alarm.
An IO-device can send up to 2 alarms simultaneously:
- one alarm of High Priority
- one alarm of low priority.
The IO-device won’t be able to initiate a new alarm of the respective priority as long as the IO-control-
ler has not “acknowledge” the previous one
By default, the PROFINET stack can handle alarm automatically without reporting any indication to
the PLC program. However, PLC can decide to manage or not by itself alarms for each device. This
can be done using the IOD_MGT_ALARM registers. With these eight 16bit registers the PLC can in-
dicate, how the firmware should for each IO-device manage alarms.
