Complete the dialog box for the data area to be transferred. For PLC5 and SLC
messages, the DESTINATION ELEMENT should be an element in a data file (such
as, N10:0). For the PLC2 Unprotected Write message, the DESTINATION ELEMENT
is the address in the module’s internal database and cannot be set to a value
less than ten. This is not a limitation of the module but of the RSLogix software.
For a PLC2 unprotected write or read function, the database address should be
entered in octal format. Additionally, the COMMUNICATION information must also
be configured. The following is an example of the dialog box.
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.
