Meeg Posted May 12, 2016 Report Share Posted May 12, 2016 Questions on the PID Controller; -Does "run Autotune" always have to be implemented to get the "run PID" working? -I can not find the "AT params struct" described in the documentation. (unistream/Unilogic? -Can the Controller be run in Auto/Manual as an ordinary Controller? -How can I set my parameters without autotuning? -Is the Controller bidirectional (positiv and negativ MV and CV) -Is it a seris or parallell PID algorithm? I have tried to use "runPID" but i struggle getting the output to behave like a normal PID Controller. Toutput does not change even if I change between reverse and Direct action (stays at minimum) , and status remain 9 or 12. Do you have any better/more detailed documentation than what is in Your help file? Regards Anders Meeg Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted May 15, 2016 MVP 2022 Report Share Posted May 15, 2016 You don't need to Autotune if you don't want to. Just set the P,I, and D values. It is critical that all the other parameters of the block be set or it won't work. Can you post your code? Joe T. Quote Link to comment Share on other sites More sharing options...

I am a teacher and we have bought a couple of Unitronics touch panels with aditionals I/O. Is it possible to make a easy startup file that include a easy PID without autotune. I see that you say all other parameters has to be set to get the PID to work. How do I do that in practice? Attached my first PID project....
