How to change AC800M SM811 AE Severity
If i understood your requirement correctly..
The AE, Alarm and Events from SM810/SM811 module will be part of system alarms. Hence this will be having/taking the Severities defined in respective processor, PM865 module settings tab.
You may change the below settings of PM865 module to change the alarm/event severity of system alarms.
If I understand your question, you might be looking for the actions defined for a particular controller error. This can be found from, Context menu of controller>>Properties>>Controller Settings.
But if you are looking for changing the severity of a particulat controller error, this is not possible as this error are defined as system errors. The FB 'ErrorHandler' or CM 'ErrorHandlerM' are used for generating a system error. You can try on your own for generating system error by using such modules and adjusting severity according to your need.
