Industrial automation technologies have made manufacturing processes increasingly more efficient. Programmable logic controllers (PLCs) are commonly used in industrial automation, and many of these ...

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 ...

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 ...

While acknowledging the potential benefits of Python and C++, engineers caution against their indiscriminate use, particularly if there are existing IEC 61131 functions available. The debate between ...

Basics of Ladder Logic provides an overview of the basic principles, structure, and symbols of ladder logic programming. This class introduces the components of ladder logic programming language used ...

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, ...

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 ...

THE use of function blocks for programming of programmable logic controllers (PLCs) is gaining wider acceptance. Rather than the classic “contact and coil” representation of ladder diagram or relay ...

As the title suggests, I'm looking for something to help me learn the basics of PLC programming. We're looking to develop the ability to do it in-house rather than wait for a contractor to come in and ...

This article is one in an ongoing series about programmable logic controllers and their applications in broadcasting. You can read past articles online at radiomagonline.com. In the last article, we ...
