Events are also generated:
• whenever any setting in the IED is changed.
The internal events are time tagged with a resolution of 1 ms and stored in a list. The list
can store up to 40 events. The list is based on the FIFO principle, that is, when it is full, the
oldest event is overwritten. The list can be cleared via the local HMI .
The list of internal events provides valuable information, which can be used during
commissioning and fault tracing.
