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 Arduino Pro Opta series has emerged as a catalyst in the world of industrial automation, offering robust and flexible solutions that cater specifically to the needs of PLC engineers. With the ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

With the Opta and Blues' Wireless Expansion, Blues and Arduino are fueling a similar revolution, empowering OT teams with a direct path to cloud-connected PLC systems." There are currently three ...

The durable Arduino Opta micro PLC enables industrial and building automation. It integrates with existing machines, devices, and the modular Arduino ecosystem – from sensor modules to SOMs and ...

For most of our prototype, hobby, or one-off electronics projects it’s perfectly fine to use a development platform like an Arduino Uno or something to that effect. They’re both easy to program and ...
