To add a ModbusTcpGateway in the station

Use the following procedure to add a ModbusTcpGateway (network) component under the station’s Drivers container.

One or more ModbusTcpGateways are supported. Often, Modbus TCP/serial gateways are on the same LAN as other Modbus TCP devices.

To add a ModbusTcpGateway in the station:

1. Double-click the station’s Drivers container, to bring up the Driver Manager.

2. Click the New button to bring up the New network dialog. For more details, see “Driver Manager New and Edit” in the Drivers Guide.

3. Select “Modbus Tcp Gateway,” number to add: 1 (or more, if multiple) and click OK.

   This brings up a dialog to name the network(s).

4. Click OK to add the ModbusTcpGateway(s) to the station.

   You should have a ModbusTcpGateway named “ModbusTcpGateway” (or whatever you named it), under your Drivers folder, initially showing a status of “{ok}” and enabled as “true.”

5. Right-click the ModbusTcpGateway and select Views->Property Sheet.

   The Property Sheet appears.

6. In the Ip Address property, enter the Modbus gateway’s unique IP address, replacing the “###.###.###.###” default value.

7. In the Port property, review the default 502 default value.

   This is the “standard” port used by Modbus TCP. If the Modbus TCP/serial gateway is using another TCP port, change this value to match.

8. Click the Save button.

9. While this network’s property sheet is open, you should review its “global” Modbus settings.

   See the next section Review network-level Modbus client configuration.
