Adding and Configuring Devices ION Setup User Guide

Typical Meter Setup Parameters

Some setup parameter groups are common and available to all meter types (such

as Basic Setup, for configuring PT and CT ratios and other system parameters).

Other setup parameter groups are available only on meter types that support

certain features (such as Waveform Capture). Refer to your meter documentation

for information on how to set up the features supported by your meter. For

information on how to use ION Setup to configure devices that are not based upon

the ION protocol, refer to the ION Setup Device Configuration Guide.

Modbus protocol considerations

Serial communications (Modbus RTU): To avoid communications problems,

make sure all devices on the serial communications bus are set to the same data

format.

NOTE

8N1 (8 data bits, no parity, 1 stop bit) is the default serial communications port setting for most ION

meters.

Ethernet communications (Modbus TCP): For meters that use Modbus TCP to

communicate through Ethernet, enter “502” in the IP Port box when adding the

meter in ION Setup (port 502 is used for Modbus TCP communications).
