2. When any other tools are connected via the USB port in a CJ2-series CPU Unit,
The following case is an exception to the rule that a local network table must be regis-
tered if there are two or more Network Communications Units mounted.
Overview:
Procedure:
After connecting online to the relay PLC, the Network Communications Unit will
be displayed in the Online Connection Information Window with the network
addresses given as “−”.
Right-click the Network Communications Unit with the smallest unit number and
select Connect from the pop-up menu to enable accessing that network.
more than one Network Communications Unit, except in the case outlined below.
Even if an online connection is made to a PLC, it will not be possible to upload or
download the network configurations unless a local network table is registered.
make the tools offline, and then connect CX-Integrator online.
Relay PLC (= target PLC)
More Than One Network Communications Unit (Ethernet Unit, Controller Link Unit,
SYSMAC LINK Unit, DeviceNet Unit, FL-net Unit, EtherNet/IP Unit, built-in
EtherNet/IP port, or Serial Communications Board/Unit (when the serial port is
treated as a Network Communications Unit))
If a local network table is not registered and a direct serial connection is
made to a target PLC in which two or more Network Communications
Units are mounted, it will be possible to access only the network of the
Communications Unit with the lowest unit number.
In this case, the network address of each network will be 0 and the
network addresses will be displayed as “−” in the Online Connection
Information Window.
Connect online to the relay PLC. Open the Online Connection
Information Window and right-click the Network Communications Unit
with the lowest unit number and select Connect from the pop-up menu.
That Network Communication Unit’s network is the only network that will
be accessible.

Local Network Table Not Registered in PLC to which a Direct
Serial Connection Has Been Made:
Access is possible only to the Network Communications Unit
with the smallest unit number, which is the Controller Link Unit
in this example.
