*2. Addresses in memory for CJ-series Units (e.g., D0000) cannot be specified directly. To access memory for CJ-
series Units, access a variable with an AT specification. (Accessing is possible only for NJ-series CPU Units.)

Precautions for Correct Use
You can execute up to 32 CIP communications instructions at the same time regardless of the
instruction types.
Use exclusive control in the user program so that the number of CIP communications instruc-
tions executed at the same time does not exceed the above number.

Route Path
The route path indicates the path from the local CPU Unit to the remote Controller on the network.
Routing for CIP communications instructions is performed based on the route path.
Route Path Notation
The EPATH data type is used to give route paths. The basic format is shown below.
Network_type_number\Destination_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
EtherNet/IP ports.
• For the built-in EtherNet/IP port 1: CPU Unit with a unit address of 00 hex (CPU #00)
• For the built-in EtherNet/IP port 2: CPU Unit with a unit address of 01 hex (CPU #01)
The
RoutePath input variable for the CIP communications instructions is used to distinguish the two
CPU Units (CPU #00 and CPU #01) and send the CIP communications instructions.
