When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...

Basic Programming for PLCs provides an overview of the basic principles, structure, and instructions of PLC programming. Most PLC programs use instructions written in ladder logic, which is a ...

In Part 1 of this two-part series, we explored PLC basics and voltage sag susceptibilities. In this segment, we present PLC voltage sag test results along with guidelines for making PLC systems more ...

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 ...
