In the previous example, the first element in the database is the starting location
for the write 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 C OMMUNICATION M ETHOD . The
P 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:
