Command #143: Read Event Logging Counters (MODBUS Reg 0xA8, 0xB0,
0xB8, 0xC0)
This command reads the four Event Logging Counters to give the number of events which have been stored in
each of the event logs. The four event logs record the most recent 10 events which have been recorded by the
instrument. These are the most recent: warning time, alarm time, fault time, and test lamp checkout time. The
event logs are stored in most recent order and going back to the least recent event. The most recent event is
event number 0 and the least recent is event number 9. If fewer than 10 events have been recorded, then the
least recent event times will indicate a time stamp of January 1, 2000.
