Abstract
A decompiler works with a compiler for an industrial controller having a user modifiable instruction table to contain code fragments necessary to compile particular instructions. During compilation, the instructions are replaced with the code fragments. Thus new instructions recognizable by the compiler may be added simply by editing this instruction table. The decompiler identifies a portion of the compiled new instructions by reference to the same instruction table used by the compiler thus maintaining compatibility with the compiler.
