Dear Wolfgang

i use zenon logic to group alarms in one general alarm using IOR Function bloc to copy the last timestamp from the input to the output. In zenon logic there is no problem every time one of the input alarms changes the timestamp of the output changes.

But in zenon runtime in AML the timestamp of the output alarm correspond to the first time when the output changes to one and does not changes even one of the input alarms changes to one ; i use zenon 11 Please see the attached image.
