Hi,

whats the difference between the above two types of PID controllers.
For example, there are the S7 PID blocks FB41 CONT_C and FB58 TCONT_CP.

Is it just that a "temperature" PID is allways pulsed heat or cool or heat/cool, or is there more to it ?

The controlling funktion is the same..
however, with FB41 are more settings possible and
takes more time to process in the CPU.
