Wide Lineup Makes It Easy to Build the Optimum System
A total of nine CPU Unit models provide for
a wide range of applications, from
small-scale systems to large. The lineup
also includes Memory Cards, Serial
Communications Boards, and a wide
selection of Special I/O Units that can be
used with any CPU Units to flexibly build the
system that meets the requirements.

Two Series of Expansion Racks Up to 50 m Long for
Long-distance Expansion with Up to 72 Units and 7 Racks
With an expansion capacity
of up to 80 Units and 7
Racks over a distance of
12 meters, the CS1 can
meet large-scale control
needs. Alternatively, an I/O
Control Unit and I/O
Interface Units can be used
to connect two series of CS1
Longdistance Expansion
Racks extending up to 50
m each and containing a
total of up to 72 Units and 7 ^{50 m}
Racks. CS1 Basic I/O Units,
CS1 Special I/O Units, and
CS1 CPU Bus Units can be
mounted anywhere on the
Racks and programmed
without being concerned
about special remote
programming requirements.
Note: C200H Units cannot be
mounted on the Longdistance
Expansion Racks.

The CS1 provides a high level of space
efficiency. As many as 960 I/O points can
be controlled by simply mounting ten Basic
I/O Units, with 96 I/O points each, to the
CPU Rack. Alternatively, as many as 80
analog I/O points can be used by mounting
five Analog Input Units and five Analog
Output Units.

Improved Refresh Performance for Data Links,
Remote I/O Communications, and Protocol Macros
In the past, I/O refresh processing with the
CPU Bus Unit only occurred during I/O
refresh after instructions were executed.
With the new CS1, however, I/O can be
refreshed immediately by using the DLNK
instruction. Immediate refreshing for
processes peculiar to the CPU Bus Unit,
such as for data links and DeviceNet remote
I/O communications, and for allocated CIO
Area/DM Area words when instructions are
executed, means greater refresh
responsiveness for CPU Bus Units.

Large Capacity CPU Units for
Greater Component Control Power
The CS1 CPU Units boast amazing capacity
with up to 5,120 I/O points, 250 Ksteps of
programming, 448 Kwords of data memory
(including expanded data memory) and
4,096 timers/counters each. With a large
programming capacity, CS1 PLCs are not
only ideal for large-scale systems but easily
handle value-added applications and other
advanced data processing.
Reduced Variation in Cycle Time During Data Processing
Instructions that require long execution time,
such as table data processing instructions
and text string processing instructions, are
processed over multiple cycles to minimize
variations in cycle time and maintain stable
I/O response.

System Bus Baud Rate Doubled
The data transfer rate between the CPU
Unit and certain Units has been doubled to
further improve total system performance.

Variation
Background processing performed over
several cycles to limit the impact on cycle
time and thus reduce variation in cycle time.
Faster Instruction Execution and Faster Overall Performance
In addition to further improvements to the
performance in the industry. Also, the new
instruction execution engine, which is the
models have a mode where instruction
core of overall PLC performance, the
execution and peripheral processing are
high-speed RISC chip has been upgraded to
processed in parallel, enabling balanced
