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 ...

A programmable logic controller (PLC) is actually an “industrial computer” that can work stably in complex environments. It can process switching signals, digital signals, analog signals, etc. from ...

Programmable Logic Controllers (PLCs) are the backbone of modern industrial automation, orchestrating critical operations across diverse sectors. As these controllers become increasingly complex, ...

Industrial automation technologies have made manufacturing processes increasingly more efficient. Programmable logic controllers (PLCs) are commonly used in industrial automation, and many of these ...

We’re all used to general purpose microcontroller boards such as the Arduino or its many imitators, but perhaps we don’t see as much of their industrial cousins. A programmable logic controller (PLC) ...

This tutorial offers an in-depth introduction into programmable logic controllers (PLCs). The article starts with an overview of the history and the role PLCs in factory automation. The basic ...
