Arduino has released Arduino PLC IDE a new version of its IDE (integrated development environment) software for use with PLCs (programmable logic controllers). The software supports the use of Ladder ...

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 ...

The following tutorial will explain how to transform the potential of popular microcontrollers into programmable logic controllers (PLCs). This primer is for those who want to begin learning about ...

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 ...

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 ...

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 ...
