Do you know how to scale your analog input? Or wire your analog output?
Many people struggle with analog signals in PLC programming. The wiring and how to use an analog input or output in your PLC program can be tricky. Most often you will see digital example PLC programs and in my Structured Text Tutorial most of the examples are digital programs.
I’m writing this article because many of you wanted to learn how to use analog signals in PLC programming. So how do you connect that 4-20mA analog transmitter to your PLC and use it in your PLC program? How do you scale an analog signal in Function Block Diagram? This article will give you answers to this and much [...]
Welcome to the first chapter of my Arduino Tutorial for Beginners. In this chapter, you will learn the very basics of the Arduino platform so that you can start programming. I will teach you how to set up your computer and write your first program for the Arduino Uno board.
The basic architecture of a PLC is important to understand. It is crucial to know about the basic PLC hardware components that are inside PLC, because it will make your understanding of the PLC much easier. The hardware components are the physical building blocks of the PLC.
