Filename: pid_temperature_control.vi
Requirements: View

This virtual instrument (VI) demonstrates how to use the "PID.vi" to implement a closed loop control strategy to control an analog process variable, such as room temperature. The feedback signal which is the temperature of the room is compared to your Setpoint and the difference between the two is used by the PID Algorithm to make a decision on what the output should be. PID parameters can be determined either by using analytical methods (Step or Frequency Response) or using trial-and error method.

INSTRUCTIONS
1. Edit your comm resource from FieldPoint Explorer and click Find Devices.
2. Configure the channel ranges using FieldPoint Explorer.
3. Save your .iak file.
4. Verify that the configuration information above matches the names in FieldPoint Explorer. If not, edit the values listed above.
5. Close FieldPoint Explorer.
6. Run this program.

I/O CONNECTIONS:
1. Connect the thermocouple signal to the channel 0 of the [c]FP-TC-120
2. Connect the control signal to the channel 0 of the [c]FP-PWM-520

This a software timed control system where the Loop Delay controls the rate of acquisition and generation.
