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.

CIP Data Table Read

CIP data table read messages transfer data to the ControlLogix processor from

the DFNT module. An example rung used to execute a read command is shown:

The M

ESSAGE CONFIGURATION dialog box must be completed to define the data

set to transfer to the processor from the module. An example of the dialog box

follows:

1 2 ... 144 145 146 147 148 149 150 151 152 153 154 ... 174 175
