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。

The following tutorial will explain how to transform the potential of popular microcontrollers into programmable logic controllers (PLCs). This primer is for those who want to begin learning about ...

Arduino has released Arduino PLC IDE a new version of its IDE (integrated development environment) software for use with PLCs (programmable logic controllers). The software supports the use of Ladder ...

Hackaday readers don’t need an introduction to the Arduino. But in industrial control applications, programmable logic controllers or PLCs are far more common. These are small rugged devices that can ...

If you’ve been reading this blog for a while, you’ve probably seen us refer to the Arduino microcontroller on a number of occasions. This little circuit board is at the heart of many DIY projects, ...

Some of the best DIY projects use microcontrollers or cheap single board computers to automate awesome stuff. But Between the Arduino, the Raspberry Pi, and the BeagleBone, it's hard to figure out ...
