IEC 61131 is an IEC standard for programmable controllers. It was first published in 1993; [1] the current (third) edition dates from 2013. [2] It was known as IEC 1131 before the change in numbering system by IEC.

2021年3月25日 · IEC 61131 is the standard for programmable controllers. It has ten parts covering general information, equipment requirement, user guidelines, communication protocols, safety, fuzzy control programming, and many other aspects regarding programmable controllers.

IEC 61131-3 is the third part (of 10) of the international standard IEC 61131 for programmable logic controllers. It was first published in December 1993 [1] by the IEC; the current (third) edition was published in February 2013. [2]

IEC 61131-3 specifies several data types (Bool, Byte, Integer, ...). These differ, for example, in the number of bits or the use of signs. It is also possible for the user to define new data types: user-defined data types such as structures and arrays.

IEC 61131-3 is the first real endeavor to standardize programming languages for industrial automation. With its worldwide support, it is independent of any single company.

This part of IEC 61131 specifies the syntax and semantics of a unified suite of programming languages for PLCs. These consist of textual languages, IL (Instruction List) and ST

What is IEC 61131, and Why is it Important? IEC 61131 is an international standard that establishes common programming languages and standards for programmable logic controllers (PLCs), which are computers used to automate industrial processes.

This Part of IEC 61131 applies to programmable controllers (PLC) and their associated peri-pherals such as programming and debugging tools (PADTs), human-machine interfaces (HMIs), etc., which have as their intended use the control and command of …

IEC 61131-1:2003 applies to programmable controllers (PLC) and their associated peri-pherals such as programming and debugging tools (PADTs), human-machine interfaces (HMIs), etc., which have as their intended use the control and command of machines and industrial processes.

IEC 61131-3 is suitable for a broad range of applications, without having to learn additional programming languages. Within IEC 61131-3, the Programs, Function Blocks and Functions are called Program Organization Units, POUs. IEC has …
