1、PLC的五种标准编程语言PLC的用户程序是设计人员根据控制系统的工艺控制要求,通过PLC编程语言的编制设计的。根据国际电工委员会制定的工业控制编程语言标准(IEC1131-3)。PLC的编程语言包括以下五种:梯形图语言(LD)、指令表语言(IL)、功能模块图语言(FBD)、顺 序功能流程图语言(SFC)及结构化文本语言(ST)。1、...
2. PLC Types Based on Hardware Setup Compact PLC A compact PLC is a small, microprocessor-based controller designed to handle small automation tasks. It consists of a built-in programming language and an extensive, user-friendly set of instructions that simplify the type of coding needed for sp...
especially, ladder diagram programming. Along with basic digital electronic logic gates concept, programming rules and you have to learn programming instructions. In the earlier tutorial, I have already explained the different types of logic gates and programming rules for writing PLC programming. If y...
In an earlier tutorial, we have studiedtimer instructionwith their types. In this tutorial, we will learn the PLC counter with a detailed explanation. Let’s start from the beginning. What is the PLC Counter? We can define the counter inPLC programmingas… an instruction which is useful for...
Online you will find many different types of PLC programming books. Most of them are about PLC programming in general. You can for example learn a lot about how a PLC works and a lot about the PLC programming languages. Especially ladder logic, which is probably the best language for beginn...
You’ll have things separated in the controller organizer such as tags, motion groups, Add-On instructions, and you’ll even have data types listed in a file-tree view. These are necessary when it comes to PLC programming, and they all work in conjunction with one another in order to cre...
“The three pillars of OOP” it might get hard to keep track of your program architecture when your program grows. As this is a common struggle in the world of the programming some smart people came up with the Unified Modeling Language. Or short UML. With UML we can visualize and ...

This is often where some confusion occurs. Because this other type of logic looks very similar to the hardware logic. In fact, the PLC programming language ladder logic is made to look like electrical circuits. Just like the input actuators you have both normally open and normally closed contac...
A PLC ( Programmable Logic Controller) is a ruggedized computer used for industrial automation. These controllers can automate a specific process. Learn about configuration, programming, implementation, and more.
