CP1H CPU Unit Operation
Section 2-3
Routing Tables
Tables specifying the communications paths from the Communications Units
on the local PLC to remote PLCs connected on other networks must be regis-
tered in all the CPU Units in network PLCs to send and receive data between
networks. These tables are called the routing tables. The routing tables con-
sist of the relay network table and local network table.
Routing tables are created from the CX-Programmer or Support Software for
Communications Units (e.g., CX-Integrator) and then transferred to each CPU
Unit.
Remote Network Table
The remote network tables lists the node number and network address of the
first relay node that must be passed through to reach any remote network to
which the PLC is not directly connected. Once the routing tables have been
registered, any remote network can be reached by passing through relay
nodes.
Local Network Table
The local network table contains the unit number and network address of all
Communications Units that are part of the local PLC.
CPU Bus Unit Setup Area
The CPU Bus Unit Setup Area contains the system settings for CPU Bus Unit
controlled by the CPU Unit. The specific settings that are available depend on
the CPU Bus Unit that is being used. Refer to the operation manual for the
CPU Bus Unit for details.
This area cannot be directly accessed by the user in the same way as I/O
memory. All settings are made from the CX-Programmer. Refer to the CX-Pro-
grammer Operation Manual for setting procedures.
