Posted 22 Jul 2015 Hello, I have ever implemented PID control in Omron's PLC using its PID instructions. (thanks to the help of Mr. PLC's posts) Now I want to know if it is equally functional under Mitsubishi's PLC cpu's? Is the code complicated? Because I might only need one or two PID control loops, the processing overhead for CPU is negligible, is it right? Many thanks in advance. Ting Share this post Link to post Share on other sites
Posted 22 Jul 2015 Take a look at this manual http://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0CCgQFjAB&url=http%3A%2F%2Fwww.fapro.com.tw%2FDB%2Fdownload%2FMitsubishi%2520PLC%2520Manual%2Fjy997d16701l.pdf&ei=PZ92VYHXN5DB7AaU-oGYBA&usg=AFQjCNG8MCvHE6ZYhdd206IbSPUiq4Kx_Q&bvm=bv.95039771,d.ZGU Steve Share this post Link to post Share on other sites
Posted 23 Jul 2015 if its older A series, then its a little more complicated than Q series, but not too bad. Q series is pretty easy if you follow the manual. Share this post Link to post Share on other sites
Posted 23 Jul 2015 Really easy? That will be quite assuring. Thank you for the manual and comparision of A and Q series. In Omron world, we ever used Loop Controller, which might be over-engineering, I think. Ting Share this post Link to post Share on other sites
Posted 24 Jul 2015 on A seires we have used external loop controllers to save trying to use the PID instructions. Q series for basic PID isn't bad at all. Share this post Link to post Share on other sites
