7. SOE /Event Log (optional)
PMAC735 provides optional function of recording up to 50 SOE events, and the records can be
kept for more than 10 years.
The SOE recording function can record the displacements of switch contacts. When an event
occurs, the meter will automatically record the type of the event such as closing of status 1. At the
same time, the year, month, day, hour, minute, second, millisecond when the event occurs will be
recorded precisely, and the resolution is 2 ms.
Users can read all the SOE records through communication. For details, refer to “SOE” (event
log).
A standard structure of SOE event data is as follows:

The basis reference of the UNIX clock is 00:00:00 January 1, 1970 (Greenwich Mean Time). For

is an 8-hour time difference between the time of Beijing time zone and the standard UNIX.
