Using the Disturbance
Overshoot Adjustment function
Longer time required
to stabilize
Faster stabilization
This function restrains overshoot when a disturbance is
generated, allowing faster stabilization.
[Example]
• Temperature drops when adding objects to a furnace
• Control disturbances when retooling
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.

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.
Loop control: Programming with function blocks to suit the application.
System configuration: Choose and combine functions from a broad selection of I/O Units.
