ABB REQ650 User Manual

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.
