May I thank everyone that has posted on this forum with regards to PID control using FB41 blocks.
I plucked up the courage last week to try one of these PID controls and ended up doing six.
All the information that I used had come from this forum.
I successfully carried out PID control loops for speed control of 3 pumps which to achieve set flowrates and to control modulating valves for process heating one cooling and two heating applications.
The blocks proved to be stable on a wide set point range.
I did get a little stuck on the cooling application which required a negative proportional band.
Has anyone tried the other Temperature PID Control FB58 (I think?) Are they any different to FB41 blocks.
Again Thanks to everybody,
