The CX-Process Tool Operation Manual is included as a PDF file
on the CX-One CD-ROM under OMRON/CX-One/CX-Process
Tool. Be sure to read the Precautions and other information at the
beginning of the manual before using the CX-Process Tool.
This CX-Process Tool Introduction Guide describes basic
operating procedures for the CX-Process Tool. For application
precautions and detailed descriptions, refer to the Help or the PDF
Operation Manual.
Note: Acrobat Reader 4.0 or higher is required to display the PDF file.

The CX-Process Tool
A Loop Controller is a Controller that has the functionality of multiple high-
performance Controllers. Combining function blocks that form functional
components enables programming control without restrictions for analog values,
such as temperatures, pressures, and flowrates.
Programming with the CX-Process Tool enables graphical engineering to paste
function blocks and connect lines with the mouse. The system also has the
following features compared with single-loop controllers and dedicated temperature
controllers.
1. The system is based on PLCs, so a wide variety of PLC Units, such as Process
I/O Units, Analog I/O Units, and Communications Units, can be used.
2. Data can be exchanged with the ladder-programmed CPU Unit at a high speed
without any programming, so loop control programming can be coordinated with
sequence control.
3. Changes, such as increasing or decreasing the number of loops and changing
the control methods, can also be flexibly performed by combining function
blocks.
A simple example of programming for one-loop temperature control will be
presented as a sample in this Introduction Guide. Function blocks can also be
combined for multi-loop control, cascade control, heating/cooling control, and
program control.

System Configuration
●This system controls one loop.
- A type K thermocouple is used for the temperature sensor input.
- The temperature range is 0.0 to 500.0°C.
- The output is 4 to 20 mA and heater control is performed using a Thyristor Unit (Power Controller).
- Continuous proportional PID is set.
Note: The default operation cycle (1 s) is used.
● The screen for the Loop Controller is displayed by connecting a NS-series PT (Touch Panel).

To simplify descriptions, operations for startup settings at the PLC
(such as creating I/O tables (see note) and setting DM Area words
allocated to Analog I/O Units) is not included in the following
description of operations for the CX-Process Tool. Be sure to
separately make the settings using the CX-Programmer.
Note: With CJ-series Loop-control CPU Units, I/O tables can be automatically generated
based on the mounted Units when the power supply is turned ON without
performing the operation to create I/O tables. (With CS-series CPU Units, an
operation must be performed to create the I/O tables.)

This section presents the flow of operations for
starting the CX-Process Tool (Support
Software), inputting the thermocouple, creating
function block data for one PID loop with an
output of 4 to 20 mA, downloading the data to
the Loop Controller, tuning PID control, and
saving files.
