Function blocks make loop-control programming easy. You can also create
CX-Process Tool tuning windows to help adjust loops. Controller faceplates
can be created automatically for touch panel displays.

Lineup includes low-cost models that use up to 50 function
blocks and models that allow up to 300 blocks designed for
large-scale systems and complicated operations.

Sequence control programs: Standardize and simplify programs using structured programming. Special I/O

Unit and CPU Bus Unit settings are easy with function blocks (using ladder programming language or
structured text).
Loop control programs: By combining function blocks, a wide array of control methods can be easily
configured, from basic PID control used by Temperature Controllers to program, cascade, and feed-forward
control. Easily display values, such as temperatures, in engineering units, allowing you to check operation.

Simple backup function enables backup, recovery, and comparison of all PLC data including the
function block programs for the Loop Control Board using the Memory Card.
Save tag settings, comments, annotations, and connection data created using the CX-Process
Tool to either a Memory Card or a Loop-control CPU Unit.

Loop control: Proven functionality of Temperature Controllers and CS-series Loop Control
Boards (see note 1) in a compact size.

parameter for Basic/Advanced/Blended PID
Blocks according to the analog input range
(zone) or input bits.

Split Converter Inputs the MV from the Basic PID block or Ad-

vanced PID block, converts the MV into two
analog outputs for V characteristics or parallel
characteristics (e.g., MV for heating or cooling)
and outputs them.

Constant
ITEM Setting

Constant ITEM Setting
(See note 1.)

Writes the constant to the specified ITEM at the
rising edge of the send command contact.

Variable ITEM Setting
(See note 1.)

Writes the analog signal to the specified ITEM at
the rising edge of the send command contact.

Batch Data Collector
(See note 1.)

Stores each of max. 8 analog inputs to buffer by
a certain timing within sequential processing.

Pulse Train
Operation

Accumulated Value In­put Adder

Adds up to four accumulated value signals.

Accumulated Value Ana­log Multiplier

Multiplies analog signals by the accumulated
value signals.

Accumulator for accu­mulated value input

Converts 4-digit accumulated value signals to 8
digits.

Contact input/Accumu­lated value output

Counts low-speed contact pulses, and outputs
8-digit accumulated signals.

Accumulated Value In­put/Contact Output

Converts 4-digit accumulated value signals to
low-speed contact pulses before they are output.

Others Analog/Pulse Width

Converter (See note 1.)

Changes the ON/OFF duration ratio in a constant
cycle duration so that it is proportional to the
analog signal.

Sequence
Operation

Contact Distributor Connect contact signals between function blocks

in a 1:1 connection.

Constant Comparator
(See note 1.)

Compares up to eight sets of analog signals and
constants, and outputs the comparison results as
contacts.

Variable Comparator
(See note 1.)

Compares up to eight pairs of analog signals,
and outputs the comparison results as contacts.

Timer (See note 1.) 2-stage output type addition timer for forecast

values and reached values. Can also output the
present value.

ON/OFF Timer
(See note 1.)

Timer for performing ON-OFF operation at preset
ON and OFF times.

Clock Pulse
(See note 1.)

Outputs a clock pulse at the setting time interval
for a single operation cycle.

Counter (See note 1.) 2-stage output type addition timer for forecast

values and arrival values. Can also output the
current va lue.

Internal Switch
(See note 1.)

Temporary storage contact for accepting relays in
the Step Ladder Program block.

Note: (One internal switch is already allocated

as “temporary storage” in CX-Process
To ol .)

Level Check
(See note 1.)

Checks an analog input for 8 levels and outputs
a contact corresponding to the level. The level
number is also output as an analog value at the
same time.

Contact Type
