The target is giving a quick overview about the theme and be used as start point for related discussions. Follow there are a short description and the configuration main steps. Alarm messages are an important tool for operation diagnose of process and system events. The object has a wide range of functionalities and covers most uses. Sometimes, however a specific alarm or all of them should be acknowledged from an external source (like an external button or a PLC variable). This simple sample brings script examples to do it. To acknowledge a specific alarm over extern button or PLC command you should use the script: HMIRuntime.Alarming.Alarms(" trigger tag : Alarm name ").Acknowledge(); TIP: if you type just "Alarm name", TIA will automatically change it to " trigger tag : Alarm name " HMIRuntime.Alarming.GetActiveAlarms(HMIRuntime.Language).then( function(AckAlarm){ for (let i=0; i<AckAlarm.length; i++){ HMIRuntime.Alarming.Alarms(AckAlarm[i].Name).Acknowledge(); } } ); TIP: in the open example, the for loop scans all active alarms. If you intend to acknowledge the first or the last alarm you can change the loop/index i for 0, or Ack.Alarm.lenght, respectively. Project archived and zipped Attachment ackAlarm.zip (1605 Downloads)

One question: If I am trying to acknowledge analogue alarms generated in my HMI (comfort panel TP1200) with an external pushbutton, will your script still work? Is it suitable for such a purpose? Kind Regards Kyle

However, every time the script runs on the 12" panel, the runtime crashes and reloads. Any thoughts or suggestions? Thanks, CC
