Hello guys,

My situation:
I had a project in Step 7 classic (v5.4) with a PLC (S7-300) and an HMI part (MP377). Since MP377 is becoming obsolete, we decided to upgrade to TP1200. The PLC code is mainly written with CFCs so we had to split the project and migrate only the HMI part to WinCC v13 (TIA).

The migration work except for the alarms (issued from the PLC). To make them work I added a proxy PLC device in my TIA portal project and initialized it with the initial Step7 classic project. Now I can see the system alarms but not the custom alarms issued from the PLC code (Alarm_S).

What I find strange is that my proxy device indicates that it had included the alarms but the "PLC Alarms" tab seems empty. Also the "Controller Alarms" does not contain any entries. I have attached a screenshot showing the above. There is no indication that the alarms were included in the TIA portal whatsoever. I don't know if that is normal though.

Any help will be appreciated.

Regards,
Kostas Patsis
