world. To improve the software used in PLCs, the International Electrotechnical Commission (IEC) has tried to define a standard for programming languages which is called IEC 1131-3. The IEC 1131-3 standard tries to bring together the languages from the PLC world and the computing world. 1.1 The use of PLCs PLCs are being used in real-time systems.

According to IEC 61131-3 standard, 5 programming languages are included : Ladder Diagram (The abbreviation is LAD) This is the most popular language today, especially in the US. It is based on the graphical representation of Relay Ladder Logic. The languages defined by the standard IEC 6-1131 for Programmable Logic Controllers (PLCs), have both benefits and drawbacks compared to object-oriented programming languages. IEC 61131 is an IEC standard for programmable controllers. It was known as IEC 1131 before the change in numbering system by IEC. The parts of the IEC 61131 standard are prepared and maintained by working group 7, programmable control systems, of subcommittee SC 65B of Technical Committee TC65 of the IEC .

IEC 1131-3-the international standard for programmable controller languages-has achieved this by applying modern software engineering principles to the best existing practices and, at the same time, providing for "extensibility", i.e. further enhancements by vendors. The author describes the development and benefits of IEC 1131-3.

Equipment and test requirements 3. PLC programming languages 4. User guidelines 5. Communications IEC 1131-3 is the international standard for programmable controller programming languages. As such, it specifies the syntax, semantics and display for the IEC 61131-3 standard is the result of a task force (IEC TC65 SC655B) comprised of seven or more international companies, representing several decades of experience in the field of industrial automation. The standard, 200 pages of text, with over 60 features tables, specifies the syntax and semantics of a unified suit of programming languages and a structuring language.

IEC 61131-3 is the third part (of 10) of the open international standard IEC 61131 for programmable logic controllers, and was first published in December 1993 by the IEC. The current (third) edition was published in February 2013. Part 3 of IEC 61131 deals with basic software architecture and programming languages of the control program within IEC 1131-3 is a standard for programming languages used in PLCs. It defines a function block diagram language and a type of Grafcet, Sequential Function Charts. An object oriented prototype of these parts has been implemented. Various execution methods are discussed.
