As engineers, we often need to design a customized control system or interface to address a need which can”t be met with an off-the-shelf interface device. In the used-to-be days, we”d get a Bud box, ...

Though PLC (programmable logic controller) programming languages may not receive the attention that general computing programming languages, such as JavaScript, C#, or Python do, they remain critical ...

A programmable logic controller, or PLC, is a software-based equivalent of a relay panel. A PLC is a general-purpose device. One model can be programmed to control a variety of machines, and programs ...

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, ...

Figure 1. SPLat Control's HMI430 programmable logic controller is based on 120 MHz ARM Cortex-M4F processor with an LCD touch panel. The HMI430 has a 4.3-in color touch screen with dimmable ...

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 ...

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 ...

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...

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