Hi Pat O'Neill,

You can use IONSetup to configure "Modbus Slave Module" ( Display in Advanced option in ION 7650 Meter ) to mapping the signals ( DI, DO ) to Modbus Register address

Please refer the guide for mapping signal to Modbus Slave Module

In Step 2: Check on "Single ION device..." and enter IP address of ION Meter

Show Advanced option in Page 4 of 9

In Step 4: You can use what area you want to mapping, Amp/Frequency...Kw/Kvar...are the default defination in ION Meter. You can rename these Area if you want

Then, you can delete Source x and Edit to "Digital In Module" or "Digital OUT module" and link to State of Sx

Then, you need pay attention to the Register Address and some properties in "Setup Register" tab ( Base Address, Format...)

Finally, Click Send to "download" configuration to IONMeter

You need to test by yourself because I just do it for mapping Electrical para before, DI and DO havve not been tested

You can also use the ION Setup Assistant, rather than go into the module level Advanced mode.

Connect to your meter using ION Setup

Open the Setup Assistant for your meter

Go to Communications > third party protocols.

In the Modbus Slave tab, select the Modbus map that you want to configure (meters ship with a Modbus map called "Default"). Click Edit to view the map.

In the viewing screen you have the option to Add values, Edit existing values, and Delete values. When you Add values you get a configuration screen that lets you define the source ION value (in your case, the I/O module outputs) the format and scaling.

Click OK to save your changes to the meter.
