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.
