Configure a TCPIP_PORT object

The configuration specific the MBTCP Communication Driver hierarchy tree under the OI Server Manager starts at the TCPIP_PORT object.

1. Configure the TCPIP_PORT object from the Configuration branch of the hierarchy after the Communication Driver has been installed.

2. Rename this object as appropriate.

   Important: If you subsequently clear your configuration hierarchy, you must create this TCPIP_PORT object from the Configuration branch of the hierarchy. From this point, all of the following instructions apply.

Create a TCPIP_PORT object from the Configuration branch

3. Right-click on Configuration.

4. Select Add TCPIP_PORT Connection from the shortcut menu.

   • A new TCPIP_PORT object is created as a node in the hierarchy tree.

   • Default name is New_TCPIP_PORT_000.

5. Rename the newly created object as appropriate.

   • The New_TCPIP_PORT_000 Parameters configuration view (right pane) is displayed.

     

   This configuration view has one element:

   • Port number: Displays the default port (socket) number, which is 502.

   Note: The MBTCP Communication Driver uses port 502 as the default port number to contact the PLC. The port number in this display is dimmed and is not changeable in this view. However, the actual port to be used by the Generic Modbus PLCs can be configured in the ModbusPLC object. This setting will override the port setting in the TCPIP_PORT object. Controllers configured under the ModbusBridge object will always use port number 502.

   From the New_PORT_TCPIP_000 branch of the Communication Driver hierarchy, the following objects can be created:

   • ModbusBridge Object

   • TSXQuantum Object (representing the TSXQuantum controller)

   • TSXMomentum Object (representing the TSXMomentum controller)

   • TSXPremium Object (representing the TSXPremium controller)

   • ModbusPLC Object (representing the Modbus Generic 4-Digit, 5-Digit, or 6-Digit controller)

   Important: Each hardware configured has a limitation to the number of connections it can support at one time. Please refer to the respective hardware’s documentation for the maximum number of simultaneous Modbus/TCP server connections it can support.

   Note: The TSXQuantum, TSXMomentum, TSXPremium, and ModbusPLC objects represent the logical endpoint to the hardware hierarchy. If you add a ModbusBridge object, you must configure an additional leaf on the hierarchy.
