Fast fourier transform algorithm written on IEC -61131- 3 Structured text programming language for programmable logic controllers. Algorithm is split-radix FFT. StFFT is iterative contrary to more common recursive approach. Iterative solution was chosen because PLCs don't have support for recursion.

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 standards body the International Electrotechnical Commission published standard IEC 1131-3 in December 1993 in order to progress towards a compatible environment.

This guide acts as a tutorial to the IEC 1131-3 standard. It describes the languages and concepts, and interprets meanings for practical implementation and application. 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.
