Internal diagnostics

  • Monitor application inactive – only works with when configured with IPMV Monitor application. Triggers alarm when Monitor application is not running.

Important options

  • Signal Duration: for how long (in seconds) selected source conditions must be triggered for the alarm to be executed. Default value: 0 seconds
  • Signal Merging: if break between multiple selected source conditions of the same time will be lower than configured value (in seconds) they will be considered as one event. Default value: 5 seconds
