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 ...

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 ...

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 ...

Programmable logic controllers (PLCs) and programmable automation controllers (PACs) are industrial computers constructed and adapted for manufacturing environments. These computers are the brains of ...

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 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, ...

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 ...
