If multiple alarms occurred (for example exceeding limit value 1 and then limit value 2, thereafter going back to 0; no alarm), a flashing acknowledgment should acknowledge all alarms, leading to the clear alarm list, the clear alarm bar and a clear screen alarming button. But in recent zenon build, only the last alarm gets acknowledgment (alarm 1 still remains in the list).
