Using the Modbus RTU Protocol ION 7500 / ION 7600 User’s Guide

Importing Data using Modbus RTU
It is possible to bring data into the meter using Modbus. Various ION registers can
be written by Modbus Master devices by correlating the Modbus register number
with the address of the ION register you want to write. When a Modbus register is
written with a value, the corresponding ION register will be written, provided the
Modbus RTU protocol is active on the communications channel that connects the
Modbus Master to the meter.
