CS1W-LCB05 Loop
Control Board
The CS1W-LCB05 Loop Control Board is a non-duplex Inner Board for the
CS-series PLCs. It can be mounted in a CS1-H CPU Unit. It is not supported
by and cannot be mounted in a CS1 CPU Unit.
Mountable CPU Unit Models
Process-control CPU
Units
The functions of Duplex Loop Control Board are built into the Inner Board of
the Process-control CPU Unit (CS1D-CPU@@P), so there is no need to
mount a separate Loop Control Board.
An Inner Board that is removed from one Unit cannot be mounted in any other
CS1D CPU Unit. Normal operation may not be possible if the Board is
installed in another CPU Unit.
The Loop Control Board mounted in the active CPU Unit is active, and the Loop
Control Board mounted in the standby CPU Unit is the standby.
CPU Units
For duplex operation, always use two CS1D Process-control CPU Units of the
same model mounted to a CPU Duplex Backplane.
Loop-control CPU
Units
A Loop Control Board is built into the Loop-control CPU Unit (CJ1G-
CPU@@P), so there is no need to mount a Board.

DPL Unit
Duplex Loop Control Boards are mounted in the Inner
Board slots of the CS1D Process-control CPU Units.
Do not remove these Boards.
