Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...
When learning ladder logic, I was told that some new PLC systems were moving to scripted programming languages. My instructor assured us that we would not need to know anything other than ladder logic ...

IL is gone, but Ladder remains—why does PLC Ladder logic survive even in the era of Structured Text?
"Ladder is outdated. The future of PLCs is Structured Text (ST)."In the world of FA, you sometimes see this kind of ...
In 1975 draftsmen were drawing electrical schematics with pencils on pieces of paper taped onto drafting boards using T-squares, 45s and 30-60s as their tools. The old-timers were still using ...
There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...
Programmable logic controllers (PLCs) are used extensively throughout the world. Over time, they have advanced to become more user-friendly, efficient, smaller, and less expensive. Different types of ...
On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...
