Max Rabiee - earned his P. in electrical engineering from the University of Kentucky. He has taught electrical engineering (EE) and electrical/computer engineering technology (ECET) courses for over 20 years.
If you have a background in digital logic gates and understand the if-statement, you can learn Ladder Logic in a matter of a couple hours. As with anything, it’s important to practice programming ladder logic if you want to get better at it.
Programmable logic controllers were initially. PLC-like programming combined with remote I/O hardware, allow a general-purpose desktop computer to overlap some PLCs in certain applications. Programmable logic controllers were initially adopted by the automotive industry where software revision replaced the re-wiring of hard-wired control panels when production models changed. Before the PLC, control, sequencing, and safety interlock logic for manufacturing automobiles was accomplished using hundreds or thousands of relays, cam timers, and drum sequencers and dedicated closed-loop controllers.
by Max Rabiee (Author). And speaking with other professionals in the PLC community, they all agreed that the book teaching us fractional binary is a complete waste of time because it's difficult and rarely, if ever, used in the real world. I/O devices and motor controls are also covered as well as commonly used number systems, such as binary and BCD. In the following chapter, students are given guidelines and examples for creating PLC ladder diagrams based on relay ladder diagrams.
