Complete the dialog box for the data area to be transferred. CIP Data Table

messages require a tag database element for both the source and destination.

The D

ESTINATION TAG is a tag defined in the ControlLogix Tag database. The

OURCE ELEMENT is the tag element in the DFNT module. The module simulates

a tag database as an array of elements defined by the maximum register size for

the module (user configuration parameter "Maximum Register" in the [Module]

section) with the tag name

INT_DATA. In the example above, the first element in

the database is the starting location for the read operation of ten elements.

Additionally, the C

OMMUNICATION information must also be configured. An

example of the dialog box follows:

Verify that the CIP radio-button is selected as the COMMUNICATION METHOD. The

ATH specifies the message route from the ControlLogix processor to the DFNT

module. Path elements are separated by commas. In the example path shown,

the first element is "Enet", which is the user-defined name given to the 1756-

ENET module in the chassis (you could substitute the slot number of the ENET

module for the name), the second element, "2", represents the Ethernet port on

the 1756-ENET module, and the last element of the path, "192.168.0.75", is the

IP address of the DFNT module, the target for the message.

More complex paths are possible if routing to other networks using multiple 1756-

ENET modules and racks. Refer to the Rockwell Automation Support

Knowledgebase for more information on Ethernet routing and path definitions.
