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 ...

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 ...

We explain to you the science (and sometimes plain logic) behind some of the most popular superstitions. Every country has its set of superstitions that are blindly followed and passed on to the next ...

Basics of Ladder Logic provides an overview of the basic principles, structure, and symbols of ladder logic programming. This class introduces the components of ladder logic programming language used ...

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...

When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...

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 ...
