Hi, I checked the ladder again and found a little mistake in the logic. ....now it works Thank's a lot for your help & comments

Thank's for the commend... I understand Status 4 means PID is running. ....but I don't understand why CV is 0 when PV differs to SetPoint

Hi Dave, thank's a lot for your response. sorry the screenshot confuses a little bit. The PV max value is multiplied by factor 100 in the ladder later...so it's actually 3000. In attached another screenshot with all values used by PID Config when Status is 4. (PID RUN) I'm not sure if all values are plausible because I don't have much experience with it.. Would be great to here from you again..

Hi all, I want to control a flow control valve using the PID function. After the autotune run is completed and the Status is 4, the CV control value goes to 0 instead of dynamically adjusting the value. May someone had the same problem when using an analog output? I would be very grateful for tips and advice.. BR, Joachim

Hello, I am new to Modbus programming and would like to ask for advice on the above topic. In my application I should write a decimal number into a register of a Danfoss control valve. What is the best way to convert a REAL value to a UINT? Below is my first draft, but I get a status error. Can someone explain to me what I did wrong?
