The contents of the buffer can be read using the
L
command, 5 events at a time.
Using the
L
command erases the previously read events from the buffer, with the
exception of events E50 and E51 which have to be reset by using the
C
command. If
a fault occurs and reading fails for example in data communication, the events can
be re-read by using the
B
command. If needed, the
B
command can also be repeated.
Events to be included in the event reporting are marked with the multiplier 1. The
event mask is formed by the sum of the weighting factors of all those events which
are to be included in event reporting.
