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.

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.

Simply turn the DIP Switch ON/OFF to save or read the

user program including function blocks using the

Memory Card.

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. Note: Supported by unit version 3.0 or later.

Optimum Tuning to Suit the Application

Fine Tuning

Adjust PVs, SPs, and MVs while monitoring, and save data as CSV files from the software tuning window. Autotuning (AT) and fine-tuning functions can also be used for automatically calculating PID constants (see note 2).

Note 1: For details on CS-series Loop Control Boards, refer to the PLC-based

Process Control Catalog (Cat. No. P051).

2:Control can be fine-tuned by automatically tuning PID parameters using previous control parameters and three user-set requirements to execute

fuzzy logic.
