About this gig

Dealing with legacy, unstructured, or uncommented PLC code? Need to migrate to modernized, platform-independent Structured Text (ST)?


With over 20 years of hands-on industrial automation experience, I specialize in analyzing, reverse-engineering, and refactoring complex logic into clean, robust, and modular ST and Instruction List (IL) configurations.


What I Offer:

* Legacy Code Porting: Seamless migration of IL / STL codebases into modular ST compatible with CODESYS, Siemens TIA Portal, Schneider EcoStruxure, or Rockwell Studio 5000.

* Code Audits & Exegesis: Thoroughly documenting and translating poorly commented foreign codes, adding professional technical comments.

* Custom FB/AOI Design: High-level algorithmic design, state machines, array handling, and complex math translations.

* Simulation-Backed Delivery: I deliver simulation recordings (using PLCSIM/CODESYS) validating that the code performs exactly as described.


Supported Platforms: Siemens, Schneider Electric (Modicon), Rockwell, CODESYS-compliant systems.


NOTE: I require your electrical diagrams and functional descriptions before starting. Let's discuss your setup first!
