Omron CX-INTEGRATOR V2 - 12-2009 Operation Manual page 95

PLCs with More Than One Network Communications Unit
If the relay PLC has more than one Network Communications Unit (see note 1), it is
normally necessary to create and transfer a local network table (see note 2).
−
Select Tools Start Routing Table to start the Routing Table Component, set the local
network table, and download it to the relay PLC.
Note 1: In this context, the following are Network Communications Units: Ethernet Unit, Con-
troller Link Unit, SYSMAC LINK Unit, DeviceNet Unit, FL-net Unit, EtherNet/IP Unit, or
built-in EtherNet/IP port: If serial ports are registered in the local network table to treat
them as networks, the serial ports must be treated as Network Communications Units,
including the serial ports on the CPU Unit. An EtherNet/IP Unit, built-in EtherNet/IP
port, or Ethernet Unit can be used.
Note 2: The local network table is one of the routing tables. It lists the unit numbers and net-
work addresses of the network Communications Units.

Not required
Required
−
Auto Online
−
Transfer to PLC.
At least one network address must be
assigned in the local network table.
The local network table must be transferred
when the relay PLC is still the target PLC to
register the correspondence between unit
numbers and network addresses.
