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.

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 ...

While robot original equipment manufacturers (OEMs) each offer their own tightly integrated controllers, recent developments now enable control by a programmable logic controller, or PLC. For ...

While PLCs (programmable logic controllers) are an industry norm, demands for data, memory, and processing power are intensifying. Soon enough, the PLCs may no longer be the go-to industrial computer.

Power-line communications (PLC) technology is becoming more widely adopted because of its excellent fit with Smart Grid efforts and other home and industry networking applications. But challenges ...
