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.
