Controller Link Units 231
Programmable
Controllers
Control up to 8 Controller Link sub-networks as a group from the host network.
Use Repeater Units for T-branch Wiring, Extension, Expansion, and Optical Sections
T-branching Enables More Flexible Wiring Solutions for Layout,
Building, and Expansion of Networks
Wired Types Support Long-distance Extension
The total extended length that was previously 500 m at 2 Mbps can be
extended to up to 1.5 km by using two Repeater Units.
Connect up to 64 Nodes Using Wired Types
Networks can be constructed with up to 62 nodes when Controller Link
Units/Support Boards with -V1 suffix are combined with Repeater
Units.
Wiring with Optical Cables Increases Noise Immunity
Using two Repeater Units for optical ring enables wiring with optical
cables in parts of the network subject to noise.
Simpler, More Flexible Data Links
Change Data Link Tables While Data Links Are Active
• When data link tables are changed due to additional nodes or
other networking changes, data link tables can be transferred
without stopping any data link communications.
• Flexible system configurations can be changed by combining
node expansion using Repeater Units.
Main Specifications Related to Version Upgrade for Unit Ver. 1.2
Note: CX-Programmer Ver. 5.0 or higher is required to set a data link area with a maximum number of send and receive words of 20,000 words
per Controller Unit, or to allocate the same area for Area 1 and Area 2.
System Configuration
Previous Units supported
connection of up to four Controller
Link Units to a single CPU Unit.
Creating a gateway to the host
network to control the Controller
Links as a group of sub-networks
required dividing the Units
between two PLCs with a
maximum of four networks for a
single PLC.
New CS/CJ-series Controller Link
Units (Wired/Optical Ring) enable
connection of up to 8 Controller
Link Units for each CPU Unit. This
enables easy centralized control of
a group of Controller Link sub-
networks from the one PLC.

Branched
by Repeater
Branched
by Repeater
Repeaters can be used for branching, so long
lines are not required. As a result, wiring labor
is reduced, and modularization is achieved in
Repeater units.
Modularization in Repeater units
enables easy removal from networ
k
or changes to connections.
No return wiring is re-
quired, making wiring
simpler and neater.
