Posted 16 Jun 2019 (edited) Hello, I make a project where I should control temperature for thermoplastic extruder. I read for this type of process a two position controller is enough but I want to use a PID controller. I have values for P,I,D,Tf and I applied Z-transform and I have a numeric controller which is implemented through structured list. I want to control heating element with this PID but my problem is I don't have an analogue output module just a digital output module(OD 212) and now my question is : How I can( if it is possible) to control duty of PWM with output from pid? (I have a CJ2M processor) Edited 16 Jun 2019 by Mike_O Share this post Link to post Share on other sites
Posted 17 Jun 2019 @Mike_O You should use TPO Instructions for change word output from PID to PWM Output. Share this post Link to post Share on other sites
