Complete the dialog box for the data area to be transferred. For PLC5 and SLC

messages, the S

OURCE ELEMENT should be an element in a data file (such as,

N10:0). For the PLC2 Unprotected Read message, the SOURCE ELEMENT is the

address in the module’s internal database and cannot be set to value less than

ten. This is not a limitation of the module but of the RSLogix software.

Additionally, the COMMUNICATION 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

PATH 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.

CIP Data Table Operations

This method of data transfer uses CIP messages to transfer data between the

ControlLogix processor and the module. Tag names define the elements to be

transferred. The following topics describe the support for the read and write

operations.
