Thank you. With the tips you gave I got it to work perfectly. I made the mistake to use the values given to me whithout questioning them, since I have an analytical chemistry background and not chemical engineering. I tuned the device now using the Ziegler and Nichols method.

Another question about this VI. The way I've wired this together my output seems to be either 0 or 20mA, nothing in between. Does anyone have any suggestions? All in One probeersel pid 17.vi

Thank you!! I got it working now. The problem was indeed that I had to set the 0-20mA as limits in the PID.

Hello all, For my work I'm trying to convert the example simulation "Simulation - Tank level.vi" to a real testrig. The simulation does exactly what we want students to do with the P, PI and PID control theory they have had. My problem is that I do not have a any experience with labview, or any other programming language. So I'm learning as I go along with this project. In my estimation this simulation I have to insert my DAQ's somewhere to get the level measurement and valve control. But I have no idea where they go, what they should replace or how to connect them to the PID node. Any help, pointers examples would be appricated Kind regards, Ivo Overmars My setup consists of Labview 2010 sp1 PID&Fuzzy logic toolkit NI9203 NI9265 PID trial 16 Folder.zip Tank Level Example.vi
