System integrators share their tips on the differences between PLCs, PACs, and Industrial PCs, including their best use cases and how to choose the right one for your environment. Allen-Bradley ...

Consider the features and typical applications for industrial controllers to understand what type of controller fits each application. Do you need a programmable logic controller (PLC), programmable ...

Analog input and output modules are a standard component in Programmable Logic Controllera (PLC) or Distributed Control Systems (DCS). More channels per module and slimmer modules bring design ...

The programmable logic controller (PLC) is a microprocessor-based system that accepts input data from switches and sensors, processes that data by making decisions in accordance with a stored program, ...

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 ...

The Allen-Bradley Micro850 and Micro870 programmable logic controller (PLC) systems use Class 1 implicit messaging capability for connectivity and design efficiency. Rockwell Automation expanded the ...

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 ...
