Configure PORT_TCPIP connection

The ABTCP Hierarchy in the Communication Driver starts with the PORT_TCPIP connection, followed by the supported communication-interface/gateway modules that allow the Communication Driver to access the supported networks and devices.The logical endpoint for each branch of the ABTCP hierarchy tree is always a Processor Type node which represents the controller device.

The following sections detail the steps necessary to configure your Communication Driver Port Objects according to your network type.

Note: Before attempting to configure your Communication Driver, you should determine the hierarchical structure of your device/network environment.

The server-specific configuration portion of the ABTCP Communication Driver hierarchy tree under the OI Server Manager starts at the TCPIP object. It is a logical representation of the Ethernet port for TCPIP communications in a computer.

Only one TCPIP object is allowed per ABTCP Communication Driver, and is added by default when you first install the OI Server. If you subsequently clear your configuration hierarchy, you must create this TCPIP port object.

Add PORT_TCPIP connection from the Configuration branch

1. Right-click Configuration, and select Add PORT_TCPIP Connection.

   An object called New_PORT_CIP_000 is created.

2. Rename the newly created object as appropriate. The Port_CIP_000 Parameters configuration view is displayed in the Configuration branch of the hierarchy.

This configuration view has two parameters, one of which is configurable:

• Port type: This information is provided automatically by the OI Server Manager (TCP/IP).

• Maximum outstanding messages: The number of messages that the Communication Driver can send to an IP address before getting acknowledgement from that destination.

  • The default value is 4.

  • The valid range is 1 to 20.

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

• PLC5_TCPIP Object (representing PLC5/20E through PLC5/80E PLCs)

• SLC500_TCPIP Object (representing SLC5/05 PLC)

• PYRAMID_EI Object (representing your Ethernet Interface 5820-EI module)
