Siemens S7-1200 SCL PI Control (Integral Windup)

Welcome to another automation video with the Siemens S7-1200 and Factory I/O.

In this video we start testing and tuning the PI Controller we implemented in Part 8.
   • PI Control using Siemens S7-1200 (SCL)  
We find that we have a combination of overshoot when filling the tank due to Integral windup which stops the controller reacting in time when we have a disturbance and therefore we program a few lines of code to stop this happening.

I would recommend viewing the Siemens S7-1200 Water Tank Level Control Parts 1, 2, 6, 7 and 8 before watching this video to put things in context.

Purchase Factory I/O
If you would like to purchase Factory I/O, you can use the link below. I will earn a small commission for this, however, it helps me produce videos like this one to help you program PLCs now and in the future and it shouldn't make a difference to the price you pay. Many thanks.
