S7 1200 Pid 3 Step Example

Hello everyone i have a s7 1200 with a analog i o module and a 0 10v actuator in a 3 step valve.

S7 1200 pid 3 step example.

Cpu 1214c dc dc dc with analog output sb1232 signal board 1 ao firmware as of v4 2 1 note. 4 ethernet connection between engineering station and controller 2 simatic step 7 basic tia portal as of v14 sp1 3 simatic s7. Then you have no problems adjusting the slope of your desired temperature curve with the parameter slewrate. The handling of this pid controller with self tuning is shown using a mixer tap as an example.

The output of your ramp is connect to the setpoint of your pid. Step 7 tia portal offers you the technology object pid 3step to control valves and actuators with integrating behavior for simatic s7 1200 s7 1500 plc. Library of general functions lgf for simatic step 7 tia portal and simatic s7 1200 s7 1500. The application on hand uses the example of a mixer to illustrate the application of the integrated 3 point stepper control of the s7 1500 automation system.

Everything went well tuning ok except when i started running the controller in automatic mode. For most purposes i would think pid compact for use with continuous input output variables would be sufficient. Otherwise can you also use the function lgf ramp from the. If you ve thought about pid on an s7 1200 you probably know that siemens is kind enough to provide two pid function blocks in step 7.

This application example provides an overview of the pid 3step technology object for commissioning with the simatic s7 1200 s7 1500. 3 simatic s7 1200 controller e g. The development environment step 7 v12 provides the pid 3step 3 point stepper control block. The digital inputs and analog inputs and outputs should be fed out to a control panel.

I ve used the pid 3step block for controlling the valve. Recently i have just made a big decision in my life by switching to data science in which i am w.
