. 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.
4.16.3 PLC5 Processor
The module can be used to receive messages from a PLC5 containing an
Ethernet interface. The module supports both read and write commands. A
discussion of each operation is provided in the following topics:
PLC5 Write Commands
Write commands transfer data from the PLC5 processor to the DFNT module. An
example rung used to execute a write command is shown in the following
diagram:
