This concept of accounting the actual alarms allows you to use standard mechanisms for the messages processing to account the alarms:

  • Alarm registration: SYS.message("alCategory", -3, "Parameter: alarm");
  • Removing of the alarm: SYS.message("alCategory", 1, "Parameter: normal");
  • Creating a list of actual (active) alarms by means of the "Protocol" or "Document" elements with the "-1" negative level for all.
