Complete the dialog box for the data area to be transferred. For PLC5 and SLC
messages, the
SOURCE 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 gateway’s internal database and cannot be set to value less
than ten. This is not a limitation of the gateway but of the RSLogix software. 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 processor to the EIP gateway.
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
gateway in the chassis (the slot number of the ENET gateway can be substituted
for the name), the second element, "2", represents the Ethernet port on the 1756-
ENET gateway, and the last element of the path, "192.168.0.75", is the IP
address of the gateway, the target for the message.
More complex paths are possible if routing to other networks using multiple 1756-
ENET gateways and racks. Refer to the Support Knowledgebase for more
information on Ethernet routing and path definitions.
