PID control in Mitsubishi PLC

5 posts in this topic

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

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

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.

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

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.
