The course felt like it went a little backward in time. We were doing programming from the standard of some 10 to 15 years ago. Instead the actual configuration of electro-mechanical devices and relays, the logic is configured in the software. That’s all it is. Heavy feat of engineering improvement (setup, testing time, etc.) – we were talking weeks and weeks of testing reduction to hours. But still, we went a little backward in time.

Don’t get me wrong. We still have this setup everywhere around the world. Simply because they were installed many, many years ago when microprocessing and programmable logic controllers were spreading widely. The only issue now is – they are starting to become obsolete.

It’s about time to upgrade to those of newer technology and style.
