A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...

How PLCs enable automated systems to be altered via software rather than hardware changes. Why PACs are often used when integrating capabilities such as safety, motion, distributed I/O, and network ...

This file type includes high-resolution graphics and schematics when applicable. Historically, motion controllers, programmable logic controllers (PLCs), and industrial personal computers (PCs), which ...

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 ...
