In the previous video (Part 1) of this Siemens PLC Training course, we configured our PLC hardware in TIA Portal V15.1.

In this video (Part 2), we are going to write a PLC program in Ladder Logic (LAD) for a simple "water pumping system".

In the next video (Part 3), you'll learn how to simulate our PLC program using the PLC simulator.

In Part 4, we will continue our PLC programming journey with another simple, yet practical PLC program.

Before we get into PLC programming we have to know what the logic behind the industrial process is. In the real situation, there are some documents for this purpose, such as Philosophy of operation, I/O lists, Piping and Instrumentation Diagrams (P&IDs), Internal wiring diagrams, and so on.
We will learn about the Control and Instrumentation documents, and drawings and how to design and draw them in software such as EPLAN or AutoCAD electrical in future videos.
In this Siemens PLC programming tutorial series, we will write some Ladder Logic PLC programs in the Siemens TIA Portal for some simple but real-world processes.
We start from the simplest PLC Programming examples and will grow to the advanced levels. You will definitely learn some useful tips and tricks in every single example that you can use in your automation projects.
You do not need any actual hardware to participate in this course. So having a laptop with a TIA Portal installed on that would be enough! In most of the examples, you can use Step 7 and WinCC as well.
