The external I/O response time in the overall system refers to the conversion time.
Ultra-small size fits in most
devices
Backplane-free structure provides
the functions you need in
minimum space.
Low-cost solution for controlling
multiple loops
Control functions have the added
ability to control multiple loops.
Consolidating the proven CS-
series loop-control technology
Effective maintenance functions
Function block programming for
easy engineering
Seamless integration of sequence
control and loop control.
HMI windows can be simply
generated from function blocks
automatically.
Super compact: Only 90 mm High and 65 mm Deep, and
Backplane-free structure enables flexible width design.
High-speed sequence control functions can be used directly for
high-speed, advanced loop control.
Compact PLC Aids Machine Downsizing by Fitting Just About Anywhere.
Wide Array of I/O Units, Special I/O Units, and CPU Bus Units Are Available to Suit Your Application.
Sequence control: Executes 20-Kstep ladder programs in 1 ms (with basic instructions only).
PCMIX = 7.4 LD or OUT executed in 40 ns
Loop control: Executes PID operations for 20 loops in up to 10 ms. This is a guide for general
applications.

Integrated Loop Control and Sequence Control
Sequence Control Engine Loop Control Engine
An engine for controlling analog quantities (e.g., temperature, pressure, flowrate) is built into the CPU Unit together
with the engine for executing sequence control, delivering high-speed sequence control and high-speed, advanced
analog quantity control in a single Unit.
