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, ...

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 ...

These small controllers deliver cost savings and many advantages over traditional methods of control. Seems like everything is getting smaller-cheaper-faster these days. So why not go smaller while ...

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 ...

To help manufacturers understand how they can mitigate potential negative impacts to production operations when message brokers are not yet or can’t be used to manage data required from PLCs, ...
