Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

用户定义功能块(UDFB)之于可编程逻辑控制器就像功能之于微控制器一样。两者都是用于简化代码的结构，使其更容易编写，故障排除和维护。它们也是允许代码在将来被重用的基本结构。 本文引用地址： 本文概述了在Arduino Opta 1中使用的简单UDFB的构造。

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 ...

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 ...

Basics of Ladder Logic provides an overview of the basic principles, structure, and symbols of ladder logic programming. This class introduces the components of ladder logic programming language used ...

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 ...

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

When we think about modernizing manufacturing, automation is the first thing that comes to mind, specifically in the form of robots and integrated lines of machines. But for Kenneth Tran, the founder ...
