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 ...

工場の生産ラインや自動化装置を動かす PLC（プログラマブルロジックコントローラ）。 PLCのプログラムと聞いて多くの方が思い浮かべるのは「ラダー図」ではないでしょうか。 ラダー図は回路図に似た表現で直感的に理解しやすく、電気制御の知識がある ...

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 ...

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...

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 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 ...

DirectSOFT5, 32-bit Windows certified programming software for the entire DirectLOGIC line of PLCs, contains many new features that make ladder logic programming faster and easier. The most important ...
