An approach to design and implement the control function of LD (Ladder Diagram) in the hydropower simulation system based on all paths searching algorithm is proposed in this paper. LD is widely used ...

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 ...

A specialized segment of the electrical construction and maintenance industry, AC motor control is an area that requires specific knowledge in order to troubleshoot motors effectively and ensure ...

Figure 1. Three-phase (three-pole) electromagnetic across-the-line motor-starters. Three-pole (three-phase) electromagnetic motor-starters (Figure 1) are commonly used to control integral-horsepower ...

This repository contains the code and documentation for Mini Project #2 in the CS 6263/ECE 8813: Cyber Physical System Security course for Summer 2023 at the Georgia Institute of Technology. In Mini ...

Though PLC (programmable logic controller) programming languages may not receive the attention that general computing programming languages, such as JavaScript, C#, or Python do, they remain critical ...

We have to admit that in the hardware hacking universe, there aren’t generally too many chances to hack elevators. Well, at least not opportunities that don’t also include the risk of incarceration.
