So you have to read the status in the PLC and copy it to the control tag of the other HMIs so that the alarm is acknowledged also . And this for all panels. All the HMIs uses an own alarm database so you cannot use the same one for all panels. So you have to use the acknowlegment tags to synchronize it. (It was the same also in WinCC Comfort/Advanced before Unified) Bye Murof

So, in this way, the alarms are centrally acknowledged. Se as reference WinCC Comfort V14 – Simple Sample: Program_Alarm
