PidControl -control module
I have managed to do pid controller for a control valve and it works fine, but now I try to do it for a pump and I can't find a right option for OUTP It should be output of a PUMP (PM210) and it is connected to a vacon drive my MV = IO.AIS.TI225.Signal and now my OUTP = IO.Tislain_DA_200.PM210.ActSpeed.Signal OUTP need a RealIO datatype and that is only one that fits for but its not the right one(?). Because of this its gives a loop when downloading.
Without knowing what Library/Blocks you use i'm just guessing but "ActSpeed" sounds like the Feedback from the Drive ("Speed Actual" Parameter on e.g. ACS800), while probably you want to connect something like "Speed Ref" (again the ACS800 Term for the Speed Reference / Setpoint, could be different for your Block).
Assuming you are using Single Control Modules, you can declare a Variable of Type "RealIO" in the Parent Object o fthe "PidControl" and connect this one to the Port, then you can access only the Variables ".Value" part for connecting only with Type "real".
If this doesn't help you, try to give more information what you want to do and some Screenshots, then probably someone may know the Blocks/Library you use and able to give detailed advice.
