from the EPM Modbus Register Map. Those selections are used to create a customized grid of up
to 256 readings in the EPM Communicator Device Profile.
Example: In order to read 1 Cycle Phase A-N Voltage as Item Number 1 on your Customized
Modbus Map, you would enter for Item 1: Line Number 10 and Point Number 0.

Each register contains 2 bytes. Each byte contains settings for a base quantity. The format of a byte
is as follows:
Digits is a 3 bit field, which is offset by 2 to represent from 2 to 9 displayable digits.
Unit is a 2-bit field, where the values from 0 to 2 represent units of Wh (100), k (103) and M (106).
The value 3 is undefined and is treated the same as 2, signifying M (106).
Decimal Places is a 3-bit field, which represent from 0 to 7 decimal places.
