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.

The standard IEC 1131–3 defines a number of interrelated languages for the expression of PLC programs. Here we consider a subset of the IEC 1131–3 languages, that of function blocks, and present an assessment of the standard from the viewpoint of providing a formal semantics to that subset.

15. 1.8 The main features of ffiC 1131 -3. 18. 1.9 Function blocks 1131-3 concepts. 31. 2.1 The IEC software model.

Overview of the IEC 61131 Standard XSeries Products IEC 61131 General INTRODUCTION 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. IEC 61131-3 standard is the result of a task force (IEC TC65 SC655B) comprised of seven or more IEC 61131-3: Programming Languages (edition 3.0 - 2013) 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.
