expanding such as multi-level temperature control, timer-
controlled temperature control, and a temperature control
relative to a variable based on a data computation results
etc. By using the new PID command (F356 EZPID), a PID
control program can be drastically simplified and the PLC-
based temperature control, which was previously thought
to be difficult by a PLC, can easily be achieved. The
example on the right, a simple uniform temperature control,
enables a surprisingly easily PID control with a single line
command by using a F356 command combined with a

0.5 ms by ensuring minimum impact on the tact time.

can be changed during a PID control execution, thereby enabling
optimum temperature control in each stage including start up, mid-
range, and convergence.
The ability to change the target value easily enables multi-step
temperature control, which was difficult only with temperature
controllers. In addition, the multi-point temperature control enables
the centralized control of multiple temperature controllers with a
single FP-X for unified data management.
