The Customizable Counter Units are CS-series Special I/O Units that can be
programmed using a ladder program and provide both standard contact I/O
and special I/O (including pulse inputs, pulse outputs, and analog outputs).
(I/O support depends on the model of the Unit.)
The I/O of a Customizable Counter Unit can be controlled by the ladder pro-
gram in it without intervention from the program in the CPU Unit to achieve
high-speed I/O processing. By customizing a Customizable Counter Unit
using its I/O, programming, and interrupt functions, a wide range of applica-
tions requiring high-speed response can be implemented in a distributed pro-
cessing system where the Customizable Counter Unit functions as a
coprocessor for the CPU Unit.
Customizable Counter Unit capabilities also facilitate machine modularization
and standardization, and make machine and device maintenance much eas-
ier.
• High-speed I/O processing is enabled by the small-capacity ladder pro-
gram in the Customizable Counter Unit that achieves a high-speed cycle.
The Customizable Counter Unit also supports various types of interrupt
programming, enabling it to handle special high-speed applications previ-
ously handled by sensor controllers and microcomputer boards. The Cus-
tomizable Counter Unit can also perform part of the functions previously
performed by High-speed Counter Units, Position Control Units, and Ana-
log Output Units.
• Other features include normal interrupts, interval timer interrupts, and
high-speed counter interrupts, in addition to a high-precision timer that
uses a pulse counter (CS1W-HCP22-V1 only), target value interrupts for
a pulse output value (CS1W-HCP22-V1 only), analog output instructions
for analog slope control (CS1W-HCA22-V1 only), and range comparisons
for the present value of a high-precision pulse output counter timer.
• The CS1W-HCA12-V1 is a special I/O unit of CS-series, having all of 1
high-speed analog input, 1 pulse input (compatible with servo drivers with
absolute encoders), 2 high-speed analog outputs, and operations by built-
in ladder program (simplified positioning, discriminant and counting pro-
cesses) within 1 unit. The unit by itself can process both the "linear sensor
