Using the Modbus RTU Protocol

 

 

Factory Modbus Configuration for the 9300 Series Meter

The 9300 Series meter makes data available to Modbus devices using four Modbus Slave modules. These modules are linked to other modules in the meter that provide energy, power and demand data. Once a communications channel is configured to use Modbus RTU protocol (refer to “Communications Setup” in Chapter 3), the data is available to Modbus Master devices.

As the data available through the Modbus Slave modules is in a specific format, knowledge of the Modbus protocol and an understanding of the settings used in the meter are required to interpret the data provided.

Changing the Modbus Configuration

If the factory Modbus configuration does not suit your needs, the existing Modbus Slave modules can be relinked to other parameters that you want to access through Modbus. There are ten Modbus Slave modules available in the 9300 Series meter, so you can create more modules to make other parameters available to Modbus Master devices.

If your Modbus Master device requires data in a format different than that provided by the factory Modbus configuration, you can edit the setup registers in the Modbus Slave modules. These setup registers specify the Modbus format, scaling and base address settings. Refer to the ION Programmer’s Reference for complete details on Modbus Slave module functionality.

NOTE

Refer to the Modbus 7300 Series protocol document for complete details on the Modbus implementation in the 9300 Series of meters.

Modbus Slave Module Settings

The settings in the Modbus Slave module setup registers are shown in the tables below. Refer to the Modbus Slave module description in the ION Programmer’s Reference for complete details of each setup register’s function and options.

Refer to the Modicon Modbus Protocol document for additional details on the

Modbus implementation in the 9300 Series meter.
