ION 7400 and PM8000 Modbus Map in ION Setup

Why Doesnt the Modbus Table show up in ION Setup as it does for the ION 7330 or ION 7550? Is it simply an oversight??

Hi Kurtis

This is not an oversight.

The PM8000 and ION7400 have a different implementation of Modbus than for instance the ION7650. They do not use Modbus Slave modules to make the default Modbus map. Instead, they have a default map based on the power data model which uses Data Mapping modules.

You can download the default Modbus map here:

http://www.schneider-electric.com/ww/en/download/document/PM8000_Modbus_Map?showAsIframe=true

It is not recommended to manually modify the Data Mapping modules.

If you need to modify the Modbus data your meter provides, ION Setup is the best tool. When you click Edit (on the screen you have shown) you will get options of Default, Modified, Custom and Disabled.

Default: uses the default Modbus map (see download)

Modified: add more Modbus values to the default mapped values. This uses Modbus Slave modules.

Custom: default map is disabled and the registers are available to use in a custom map created with Modbus Slave modules. (this is intended for retrofit applications where you need to make the meter's Modbus data match with a previous device)

All of this information is described in the PM8000 user manual, 7EN02-0336-01 page 49-58 and in the ION7400 user manual.

cheers,

Alana
