Readout of the event
memories
There are eight event memories for each type of event. The latest event is stored in
event memory 1, the previous one in event memory 2, and so forth.
Readout of event memories is illustrated using the fault memory as an example.

2 Press the ‘right’ key repeatedly to see first
the measured fault data and then the binary
signals in chronological order. The time shown
in the second line is the relative time,
measured from the onset of the fault, at which
the value was measured or the binary signal
started or ended.
Once the end of the fault has been reached
(after the ‘right’ key has been pressed
repeatedly), pressing the ‘right’ key again will
have no effect.
