My output from my PID block is a Manipulated pump speed but when I try and change the set point nothing seems to happen |

First we should know your plan regarding the binary output (to run the motor) and the analog signal (to change the speed). First , we need to clear if you have done all requirement in software in a correct way.Please:

Hi, I have uploaded a simplier version of my project in contsin my OB1 OB35 and the DBs. What I wanting to do is to fill a tank to a setpoint using the PID block. The actuator to be controlled is a pump with a varible motor speed and a ultrasonic level sensor is used for the level control. regards

It is easy it for it by yourself.Copy each section of codes and stroke key combinations "CTRL+3" and "CTRL+2"

What was there error?I create an FBD version of program both in OB100 and OB3X.Please just copy the idea and customize that to your application.In OB100, you call PID with COM_RST active with exact DB that is used on OB3X.It is for initialization purpose.At the end of OB100,COM_RST resets but Man_on is active for starting cyclic execution stopping with LMN=Man.

and for normal operation, parameterize SP_INT and PV_IN. For troubleshooting the PID part, we need the VAT I uploaded some days ago.To energize the pump, please fine the R-Prior flip-flop with a spare rest signal while tank is getting empty and PID can not regulate.AttachmentOB35.zip (253 Downloads) |
