You can always attach a variable, for example a global variable to the HWstatus property of any S800 I/O module and according to the value, you can create an alarm on your CBM project, you can use the alarm_cond/alarm_Cond_basic/Signal_Event function blocks to generate the alarm in your AC800M controller, then trough the AE OPC you get the AC800M alarm on PPA. You must check the alarm class and severity properties of the function blocks to match the alarm priority configuration you made on PPA.
For AC800M, you can change the priority of I/O alarms from control builder.
Go to the controller (ex pm866) in control builder and open settings then look for the AE system ae severity and change it to a value required for priority 4 .
The alarm priority mapping for each severity can be found in OPC AE server for AC 800m in alarm collection definition.
