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 ...

Rockwell Automation announces the new Allen-Bradley Micro820 programmable logic controller (PLC), a new addition to the Allen-Bradley Micro800 PLC family. The 20-point Micro820 controller features ...

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, ...

When electronics release the Magic Smoke, more often than not it’s a fairly sedate event. Something overheats, the packaging gets hot enough to emit that characteristic and unmistakable odor, and ...

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 modern programmable logic controller (PLC) is at the nexus of two debates that are taking place daily at opposite ends of the control-system spectrum. At one end is the debate over the ideal ...

In its third major and field-programmable gate array (FPGA) announcement in the last 12 months, Lattice Semiconductor Corp. has introduced MachXO, a new product family that combines the key features ...

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 ...
