In the previous example, the first element in the database is the starting location
for the write operation of ten elements. 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.
CIP Data Table Read
CIP data table read messages transfer data to the processor from the gateway.
An example rung used to execute a read command is shown:
