CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
The route path indicates the path from the local CPU Unit to the remote Controller on the network.
Routing is performed for CIP communications instructions based on route paths.
The EPATH data type is used to give route paths. The basic format is shown below.
Network_type_number \Remote_address
The network type number and the remote address are determined as shown in the following table
according to whether the route type is (1) a Unit on the CPU Rack or (2) a communications port on a
Communications Unit.
(1) When Routing the Output to a Unit on the CPU Rack
Output the command to the backplane port as a network with the CPU Rack. Specify the
Unit address as the address of the remote Unit.
(2) When Routing the Output to a Communications Port on a Communications Unit
Output the command to an EtherNet/IP port. Specify the IP address as the address of the
remote node.
Additional Information
Unit Addresses
A Unit address is used to discriminate between several devices connected to a single node on a
network.
Set the unit address as shown below.
•
CPU Unit:
00 hex
•
CPU Bus Units (EtherNet/IP Units):
Unit 10 hex
•
Special I/O Unit:
