An overview of the hardware and software components of PLCs and their programming languages. A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and ...

Abstract: This research presents a real-time automatic control system for ensuring reliable power supply in distributed generation systems. Leveraging Programmable Logic Controllers (PLCs) and ...

Programmable-logic devices provide a popular method of implementing complex functions in digital designs. Although manufacturers don't yet offer analog circuits whose complexity compares to VLSI ...

There are many industrial applications, such as programmable logic controllers, that require efficient, low cost, step-down power conversion over a wide range of voltage levels. This paper discusses ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...
