Configure the following setup registers as needed: Slave Address, Register Address, Number of Registers read by the module, Format and scaling requirements. The supported Slave Address range (Unit ID on ION meters) for a Modbus device is from 1 to 247.

5.Repeat steps 2 - 4 for every meter or TRAN in the serial network whose data you wish to display on the meter with the front panel.

The meter with the front panel requires a separate Modbus Import module for each meter whose data it displays, because all meters in the network have unique Unit IDs. This is how the Modbus Master distinguishes which meter (Slave Address) is providing what data (Register Address).

6.Link each Modbus Import module’s output registers to the appropriate Display module’s Source inputs.

7.Define each Display module’s characteristics (display format) by adjusting its setup registers. Do the same to the Display Options module if so desired.

8.See “Removing a Display Screen” on page 198 for considerations on re-linking Scroll module Trigger outputs.

This step is important if you want to have your new screens appear in an automatic scrolling cycle, or if your custom framework has fewer display screens than the factory configuration, and you need to adjust the Scroll module’s settings.

9.Send & Save changes.
