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 ...

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 ...

The programmable logic controller (PLC) is a microprocessor-based system that accepts input data from switches and sensors, processes that data by making decisions in accordance with a stored program, ...

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 ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...

If your usual tools are the Arduino and the Raspberry Pi, you might find it surprising that the industrial world tends to run on Programmable Logic Controllers, or PLCs. You can think of a PLC as a ...

Being nimble and quick isn’t about fun and games for Jack Piper. It’s serious business for the engineering manager at Ridgeline Pipe Manufacturing in Eugene, Ore., because it’s his job to squeeze ...

This file type includes high-resolution graphics and schematics when applicable. One of the key parts of automation is observing variation, and a process’ ability to control it. Reducing variation ...
