2-1 Basic Procedures
Uploading
Network
Configurations from Target PLCs other than the Relay
PLC
The network configuration of another PLC can be read via the PLC that was first
connected to the computer (known as the relay PLC). To read another PLC’s network
configuration, switch the target PLC from the relay PLC to the desired PLC connected.
At this point, it is possible to upload the configuration of the network (including
component parameters) of the network connected to that target PLC.
Note: When accessing a target PLC other than the relay PLC, observe the following two pre-
cautions, set routing tables, and transfer them to the PLCs.
•
Always create local network tables and transfer them to the relay PLC and target PLC.
•
When specifying a target PLC in another network, register both local network tables and
relay network tables in all of the PLCs on the path between the relay PLC and target PLC.
Overall Procedure
Connect online to the relay PLC.
Start the CX-Integrator.
Create the local network table.
Create the local network tables
and relay network tables.
Transfer the routing tables to all PLCs
between the relay PLC and target PLC.
Required when the target PLC
is on a remote network.
Example: Select Component
