This paper attempts a journey right from configuring a PLC, writing application program to code generation along with run-time configurations and RTOS abstraction for embedding it into PLC hardware ...

IEC 61131 was previously known as IEC 1131. See PLC. Graphical ladder logic function block diagram sequential function chart Textual structured text instruction list ...

Five different programming languages — ladder diagram, function block diagram, structured text, instruction list, and sequential function chart — are defined in the IEC 61131-3 standard, as ...

While I believe ladder logic is the optimal programming language for the PLC, there are at least two other methods of which the reader should be aware: Functional Block Diagram and Structured Text ...
