Hi

The "GetActiveAlarms" method is asynchronous and returns a Promise rather than an AlarmResult. Therefore, it is better to evaluate the promise using the then() and catch() functions.

HMIRuntime.Alarming.GetActiveAlarms(Language[,Filter][,SystemNames])
.then(function(HMIAlarmResult[]) {
  ...
})
.catch(function(ErrorCode) {
  ...
});

Kind regards
Stefan

Hi Rsmitsitel,

The required functionality must be placed inside the then() handler.

export function Task_CyclicIDExport_Update() {
  const maxIDs =30;
  let alarmIDs = [];

  HMIRuntime.Alarming.GetActiveAlarms(HMIRuntime.Language)
    .then(function(alarms) {
      alarmIDs = alarms.map(alarm => alarm.ID).slice(0, maxIDs);

      // Write each alarm ID to its corresponding tag
      for(let i = 0; i < alarmIDs.length; i++) {
        HMIRuntime.Tags("DugaAux_IDs["+ i +"]").Write(alarmIDs[i]);
      }
    });
}

Kind regards
Stefan

Hi Radim,

As a quick tip, you can debug scripts when using WinCC Unified PC RT or the simulation. This will provide more information on why the script is failing.

Kind regards
