One Zone

The TECT_TEMP_CONTROL is the kernel control Function Block, which does the control process. The input is the actual temperature feedback from the analogous sensor mounted inside the temperature zone. The outputs of the control is a PWM signal, which controls the process. It can be binary outputs, which switch the heater and cooler directly or analogous signal in duty cycle (%).

The zone data structure contains all set and status values, which are relevant for the process. The set values can be written from the user, whereas the status values can only be read, e.g. using a CP600 HMI operating panel. It is also the common interface for most of other Function Blocks in PS564 library.

The Function Block TECT_TEMP_SIMU can be used as one zone simulation instead of a real zone for test purpose.
