A Programmable Logic Controller (PLC) is a specialized computing system widely used to control real-time industrial processes and assemblies. The block diagram of a generic PLC is shown in Figure 1.

PLC evaluation board applications for industrial process-controlsystems are diverse, ranging from simple traffic control to complexelectrical power grids, from environmental control systems ...

Narrow-band low-frequency power-line communications (NB LF PLC) is a hot topic these days. Engineers creating PLC modems must consider which PLC standard (PRIME, G3, S-FSK) will be used and which ...

This file type includes high-resolution graphics and schematics when applicable. One of the key parts of automation is observing variation, and a process’ ability to control it. Reducing variation ...

As end-users take advantage of more capable PLCs, they must also consider security. By increasing the overall computing power of PLCs, controller vendors have made room for additional capabilities.
