PWM Output Module User’s manual
This is an example about PID temperature control of the heater which turns on at
24V and turns off on at 0V. Basic requirement of the system is as below.
<Requirements>
Temperature value of the system should be controlled by PID control.
MV value should be applied to control every second.
The device should be controlled by the ON-OFF button.
MV value with range from 0 to 16000 should be applied as range from 0.0%
to 100.0%(Duty cycle control).
Entire scan program is as below.
(1)
Create a new PID program.
