Hi,

“Simple Samples” are small projects that demonstrate simple features. 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.

Hi,

This scripts work fine when we want to acknowledge Discrete Alarm. I have tried for program alarms but it’s not working. Do you have any solution to acknowledge Program Alarms?

Thank you

Hi,

I am using TIA 19 UPD 3. And Acknowledge working if I am using alarm control.

thanks.
