INTRODUCTION GUIDE

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 highperformance 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.

● 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).

Loop Controller

(in CJ-series CJ1G-CPU45P Loop-control CPU Unit)

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.)

Creating Simple Function Block Data for the Loop Controller

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.
