The function does not have any parameters available in the local HMI or PCM600.
20.5.5 Operation principle
The self-supervision operates continuously and includes:
• Normal micro-processor watchdog function.
• Checking of digitized measuring signals.
• Other alarms, for example hardware and time synchronization.
The self-supervision function status can be monitored from the local HMI or from the Event Viewer
in PCM600.
Under the Diagnostics menu in the local HMI, the actual information from the self-supervision
function can be reviewed. The information can be found under Main menu/Diagnostics/Internal
events or Main menu/Diagnostics/IED status/General. The information from the self-supervision
function is also available in the Event Viewer in PCM600.
