Modicon M340 Pid Autotune

[ControlWORX]

Hello all. Anyone used the AutoTune Function on an M340 w/ Unity Pro XL??? Got an injection mold machine retro. and I would like to try it out. I can't seem to get the auto block to cooperate.

Thanks Travis

Did you see the Controller coupling DFB ? I am trying to do autotuning thru this method . With normal PID I am getting 7 to 8 degC deviation in temperature. People say Schneider is best for process control ,I am trying to figure out how? Their support too is drying out just like Rockwell.
Well keep trying. It should work with controller coupling. As it is given in the help.

Well, I could manage to get PID autotuned in M340.
