Sample Programming
In this sample, the PIDAT_HeatCool instruction is used to perform temperature control. There is one
analog thermocouple input from the controlled system. There are two outputs to the controlled system,
a heating digital output and a cooling digital output. The heating digital output turns the heating device
ON and OFF. The cooling digital output opens and closes the solenoid valve for the cooling water.
