A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
Utility companies use special coupling capacitors to connect radio transmitters and receivers to the AC power-carrying conductors. Power meters often use small transformers with linear amplifiers in the range of tens of watts. Most of the expense of any PLC system is the power electronics.
Founded in 2000, the HomePlug Powerline Alliance's goal was to create a standard to use existing home electrical wiring to communicate between products and connect to the Internet. [2] The first HomePlug specification HomePlug 1.0 was released in June 2001.
Home automation software is software that facilitates control of common appliances found in a home, office, or sometimes a commercial setting, such as lights, HVAC equipment, access control, sprinklers, and other devices. It usually provides for scheduling tasks, such as turning sprinklers on at the appropriate time, and event handling, such as ...
Broadband over power lines (BPL) is a method of power-line communication (PLC) that allows relatively high-speed digital data transmission over public electric power distribution wiring. BPL uses higher frequencies, a wider frequency range, and different technologies compared to other forms of power-line communications to provide high-rate ...
The IEEE 1901 Standard, established in 2010, set the first worldwide benchmark for powerline communication tailored for multimedia home networks, audio-video, and the smart grid. This standard underwent an amendment in IEEE 1901a-2019, introducing improvements to the HD-PLC physical layer (wavelet) for Internet of Things (IoT) applications.
