Functions

CONTROL & PROGRAM CONTROL

Flexible Control for a Variety of Application

Integration of Control and Recorder Functions

PV Math/SP Math

PV math/SP math can be used in PID computation.
PID-computed result are used as PV or SP. By using the PV or SP that is evolved from original know-how, CX can control accurately in variety of applications.


PV math/SP math

Functional Program Operation

Synchronous or independent program operation up to 6 embedded loops

As program operation is available for each loop, the CX can be applied for a variety of applications. Up to 30 program patterns can be set.


Independent multi-program pattern operation Synchronous multi-program pattern operation
Up to 6 program patterns can be controlled independently
Example: Independent program operation for 6 furnaces using the CX2620
Up to 6 program pattens can be controlled in the same time period
Example: Synchronous program operation for a furnace using the CX2620
Independent multi-program Synchronous multi-program


Simultaneous use of program operation and fixed-point contol mode Distinguished display of program pattern process
Example: Synchronous program operation for 3 loops, fixed-point control mode on one loop using the CX2420 Program pattern and PV can be displayed one on top of the other during program control
Simultaneous Distinguished display


Program pattern and program events can be displayed simultaneously
