Note When I/O tables for configurations with Communications Units
used in duplex operation are created, the Unit with the lower slot
number will be designated as the active Unit and the Unit with the
higher slot number will be designated as the standby Unit. To re-
verse this designation, edit the I/O tables offline and transfer them
to the PLC.
8. Set the transmission path format using software switches in the DM param-
eters area.
• Token-ring mode or token-bus mode
Note This setting is made for Optical Ring Controller Link Units only. (It
is not required for Optical Bus Systems because the token-bus
mode is always used.)
9. Register routing tables.
Note This setting is required only for connection between networks or
when using CVM1 or CV-series PLCs.
Set the data link mode in the data link parameters in the DM area of the star-
tup node to either automatic or manual data link creation using the Program-
ming Device.
Manually Setting Data Links
1. Register data link tables for all nodes using the Controller Link Support
Software or CX-Programmer.
2. Start the data links either using the Controller Link Support Software, CX-
Programmer, or by turning ON the Start Bit from the Programming Device.
Automatically Setting Data Links
1. Set the DM area of the startup node using the Programming Device.
2. Start the data links by turning ON the Start Bit from the Programming De-
vice.
Execute communications instructions in the program.
• CX-Net in CX-Programmer can only be used in systems with a maximum
of 32 nodes (node addresses 1 to 32). For systems with more than 32
nodes, use Controller Link Support Software (Ver. 2.00 or later).
• Turn OFF the power of all the nodes on the network before connecting or
disconnecting a cable.
• Use the specified cable only.
• Be sure to set routing tables for CVM1 and CV-series PLCs. When a
CVM1 or CV-series PLC is connected to the network, set routing tables at
all the nodes.
