Tia portal "program_alarm" instruction as information only

Hello,

I am trying to implement a logging system in TIA Portal V20 using the PROGRAM_ALARM block.

It works well overall — I can see alarms appear in the WinCC Unified Alarm Control, and they are correctly logged.

However, when I enable the "Information Only" option, the alarm becomes invisible in WinCC Unified — it shows up neither in the pending alarms view nor in the alarm log.

Does anyone know the solution?
