Programmable logic controllers (PLCs) are widely used in industrial electronic systems. With the augmenting complexity of system, the reliability poses a crucial challenge in safety critical ...

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 ...

Knowing how to draw a ladder-logic diagram and read it was an indication of industrial-production literacy and skills. Q: How did the name programmable logic controller come about? A: It’s an ...

Programming via IL is easy but the ambiguity in defining logic relationships makes troubleshooting difficult. A sequential function chart (SFC) programming language is the middle-ground between a ...

The physical idea of using your board as a PLD looks like this: The logic inputs for A and B are connected to digital input pins. The resulting output Q is connected to a digital output pin. We can ...

The IEC 611131-3, an open international standard for Programmable Logic Controllers (PLC) defines several domain specific languages for industrial and process automation. Domain specific languages ...

A Complex Programmable Logic Device (CPLD) is a great piece of hardware to have in your repertoire. As its name implies, you can program these chips to serve the logic functions you need. This migh… ...
