The VP-2040 provides optional function of recording up to 50 records
of Sequence of Events (SOE), 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 and
Modbus RTU protocol. For details, refer to Chapter 9 - Register Map
Profile .
A standard structure of SOE event data is as follows:
