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 ...

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 ...

Programmable logic controllers (PLCs) are used extensively throughout the world. Over time, they have advanced to become more user-friendly, efficient, smaller, and less expensive. Different types of ...

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 ...

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 ...
