Sub-Metering with a Modbus Master Technical Note
Customizing the Modbus Master Framework
The Modbus Master framework is designed to handle 12 Modbus Slave devices.
This is limited by the number of Modbus Import Modules supported by ION
meters. Each Modbus Slave device uses five Modbus Import Modules, two
Arithmetic Modules, and two Data Recorder Modules. If you do not require all 12
Modbus Slaves, you may want to remove some the extra Sub Meter folders from
your framework. Deleting unused Sub Meter folders will free unused resources
on your meter.

Once all unused Sub Meter folders have been deleted, verify that the Unit IDs in
each Sub Meter folder of your framework corresponds to the Unit IDs of the
meters on your Modbus Network. To verify Unit IDs, right-click on each Modbus
Import Module in a Sub Meter folder and verify the value in the Device Name
setup register corresponds to the Unit ID of your meter.

Multiple Modbus Master Devices
After you have pasted and customized the Modbus Master framework into one of
your meters, you can then use this framework to paste into the other Modbus
Master meters in your site. The following procedure describe how to copy the
Modbus Master framework into several Modbus Master meters. Follow the steps
outlined below to ensure framework consistency across each meter in your site.

When pasting your customized Modbus Master framework, it is important to “lock paste” the modules
into the meter so that all the Modbus Master meters have identical frameworks. This is particularly
important when creating Vista diagrams that are compatible across the different Modbus Master meters.
