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 ...

When learning ladder logic, I was told that some new PLC systems were moving to scripted programming languages. My instructor assured us that we would not need to know anything other than ladder logic ...

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 ...

PLCとは Power Line Communication の略で、電力を通信回線としても利用する技術です。端的に言えばコンセントに差して使うネットワークで、かつて流行りそうだったものの諸般の事情により普及しなかった通信方式です。しかし今日はこのPLCの話ではありません。

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...

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 ...

の、不連続の続編となります。「不連続の」の時点で続編たりえないのですが、まあ、ある種間違い探しみたいなものです。某外食店に置かれている間違い探しと同様に「何も間違っているわけではない」のですが、差異を楽しんでいただけたら幸いです。
