TRM-STAT TermStatus - Internal Events
The list of internal events provides valuable information, which can be used during
commissioning and fault tracing.
The internal events are time tagged with a resolution of 1ms and stored in a list. The list
can store up to 40 events. The list is based on the FIFO principle, when it is full, the oldest
event is overwritten. The list cannot be cleared and its content cannot be erased.
The internal events in this list not only refer to faults in the IED, but also to other activities,
such as change of settings, clearing of disturbance reports, and loss of external time
synchronization.
The information can only be retrieved from the Parameter Setting software package. The
PC can be connected either to the port at the front or at the rear of the IED.
These events are logged as internal events.
