Configuring a Modbus Network

Unlike BACnet, only one Modbus TCP device is added to the “network” during discovery according to the device information entered. For multiple Modbus devices, create multiple Modbus “networks.”

For an overview, watch the video below (until the 1:33 mark). For details, consult the following written information.

1. Go to Networks Explorer , then Networks.

2. Select Configure New Network to go to the Configure Network page.

3. For Protocol, select Modbus.

4. Enter the relevant network information in the fields.

5. Upload the Modbus register map CSV file for the particular Modbus TCP device:

   1. Next to Map File, select Upload.

   2. Select Choose file.

   3. Locate the map file on your computer.

   4. Select Upload.

   Note: For full instructions about the Modbus TCP device options as well as sample register map CSV files, see the Modbus Devices on KMC Commander Application Guide (see Accessing Other Documents).

6. Choose the Network Interface from the dropdown list.

7. Select Save.

Continue with Configuring Devices.
