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

Optimum Tuning to Suit the Application
Disturbance Overshoot Adjustment
Fine Tuning
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).
