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.
You can use the Modbus RTU protocol to write values into ION external numeric,
pulse and Boolean registers, allowing you to enable, disable and reset meter
functions. You can also use the Modbus protocol to change setup register values in
various ION modules to configure the meter’s operation.To bring data into the
meter with Modbus RTU, you must disable the meter’s password security.
