Installation Section 3-2
3-2-3 CS1D PLCs
Up to 3 pairs (i.e., active Unit and standby Unit) of CS-series Controller Link
Units used in duplex operation and one CS-series Controller Link Unit not
used in duplex operation can be mounted to a CS1D Duplex Backplane or an
Expansion Backplane supporting online replacement. In other words, Units
using up to 4 unit numbers can be mounted. Controller Link Units cannot be
installed on an C200H Expansion I/O Rack or a SYSMAC BUS Slave Rack.
Note 1. Duplex operation is possible only with the CS1W-CLK12-V1 and CS1W-
CLK52-V1.
2. Tighten the screws on the Backplane to a torque of 0.9 N • m.
Tighten the fixed screws on the CPU Unit to a torque of 0.4 N • m.
When installing several CS-series CPU Bus Units at the same time, a total of
16 CS-series CPU Bus Units maximum (not including Controller Link Units in
standby mode) may be installed.
For details on the CS1D System, refer to the CS-series Duplex System Oper-
ation Manual (W405).
Note 1. A pair of Controller Link Units used in duplex operation can be mounted in
non-adjacent slots or on different Racks. Be sure, however, to connect
them directly with a cable.
2. In the CS1D System, online replacement is possible using a Programming
Console. If the Controller Link Units are used in token-bus mode, however,
there is a possibility of the network splitting.

Controller Link Units cannot be
mounted to Expansion I/O slots.
Units corresponding to up to 4
unit numbers can be mounted.
Possible configurations include
the following:
1. Controller Link Units used
in duplex operation can be
mounted to 6 slots (3 lots
for active Units and 3 slots
for standby Units) and a
Controller Link Unit not
used in duplex operation
can be mounted in 1 slot.
2. Controller Link Units not
used in duplex operation
can be mounted to 4 slots.
