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