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 ...

This tutorial offers an in-depth introduction into programmable logic controllers (PLCs). The article starts with an overview of the history and the role PLCs in factory automation. The basic ...

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 ...

For PLC programming, U.S control engineers and technicians turn typically to ladder logic, a programming technique that’s been around since the birth of programmable logic controllers, or PLCs, in the ...

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 ...

An HVAC company in search of modern machine-control advantages finds an Arduino-compatible open PLC controller is the solution. Like many modern-day makers and hobbyists, I have always been inspired ...
