Festo Didactic: Programmable Logic Controls - Basic Level

This video illustrates Programmable Logic Controllers at a very basic level - Training System for control technology. The video is made by and owned by Festo Didactic. I stake no claims over the ownership of the video. The sole purpose of uploading this video was to help students learn.
If anyone has any problems with the video being uploaded, please write to me and I will take it down. I am not making any money on these videos and thus these videos should always be ad-free. If youtube starts putting ads here, please let me know, I'll try to make it harder for them.
Some other learning material that I found along with the videos are shared, here's a Google Drive link, that will give you access to books and maybe some software:
