Route Path

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.
Route Path Notation
The EPATH data type is used to give route paths. The basic format is shown below.
Network_type_number \Remote_address
 NX701 CPU Unit and NX102 CPU Unit
Two internal CPU Units are provided (each with a unique unit address) to control the two built-in Eth-
erNet/IP ports.
• For built-in EtherNet/IP port 1: CPU Unit with a unit address of 00 hex (CPU #00)
• For built-in EtherNet/IP port 2: CPU Unit with a unit address of 01 hex (CPU #01)
In the route path of the CIP communication instruction (RoutePath in-out variable), add entries that
recognize the above two CPU Units (CPU#00 and CPU#01) before sending the CIP communication
instruction.
Route path when sending a CIP communication instruction
• When issuing a CIP communication instruction, issue from CPU #00. (a)
• To output from built-in EtherNet/IP port 2, output from CPU #00 via CPU #01. (b) to (c)
