CIP Driver Tag Type: Connection Tab

The Connection tab for a CIP driver enables you to configure the port through which communications with the hardware will take place.

Note: The TCP/IP Port Tag should be usually be configured to communicate with the PLC on port 44818 (0xAF12). You should confirm this against your PLC’s configuration.

Port

The Port field enables you to select the TCP/IP tag you wish to be associated with this driver (this will be the TCP/IP tag that is representative of the physical TCP/IP socket to which the physical PLC or RTU is connected).

The Port field can be used to associate this tag with a new or existing TCP/IP tag using the  button. This button opens the Tag Browser, that displays only the existing TCP/IP tags for your application, and enables you to create a new TCP/IP tag using its New button.

The Port field can be cleared using the X button that appears to its right.

Port Segment Path

[Port #, Link Address][Port,Addr]

The Port Segment Path format is [Port ID, Link Address], and describes the path to access the data. The Port ID is a number which describes the port to access the data. Port ID 1 is defined as the backplane of a PLC. The Link Address is the address of the item with which to connect.

For example Link Address 0 is Slot 0 of the backplane. If simply connecting to an Ethernet port on a CPU card, this value parameter should be set to [1,0].

Note: You must be familiar with the hardware to which you are connecting in order to correctly establish the Port Segment Path.

Hold

The Hold checkbox indicates whether this driver should hold data from the PLC or RTU in the event of a communications failure.

If the Hold checkbox is selected, the last received value from the PLC or RTU will be held.

If the Hold checkbox is not selected, the data will be invalidated in the event of a communications error.

By default, the Hold checkbox is not selected.

Retries

The Retries spin box enables you to select the number of attempts that will be made by this driver if there is no reply to a message. An error will be declared after this number has been reached.
