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 ...
In part one of this series, we looked at the PLC’s internal architecture, briefly discussed Ladder Logic programming, Human-Machine Interfaces, advantages of the PLC’s ability to react consistently ...
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 ...
Power-line communications (PLC) is becoming a key communications technology. Thanks to new standards and a flood of new chips and products, PLC is finding a place in home area networks (HANs), the ...
