PI Control using Siemens S7-1200 (SCL)

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

In this video we add the integration part of a PID controller to the proportional part we implemented in the previous video and we program it in SCL code to control the water level in a tank. (PI Control)

We also show how to calculate the total error by estimating the area under the curve which is key to the programming the integral part of a PID controller.

I would recommend viewing the Siemens S7-1200 Water Tank Level Control Parts 1, 2 and 6 before watching this video.

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.
