AUTOMATION SOFTWARE · PLC ANALYSIS

Analyse your Siemens TIA Portal projects with AI.

LSA — Logic Scope Analyze reads TIA Portal archives (.ap*) and answers your technical questions based on the real project code: PLC logic, blocks, variables, HMI. No more hours spent digging through an inherited project to understand what it does.

What it does

LSA loads the archive of a TIA Portal project and builds a semantic understanding of it. You can ask in plain language what a block does, where a variable is used or what changed between two versions — and get answers grounded in the real code, not invented. It's the fastest way to understand, document and safely modify a PLC/HMI project.

Who it's for

  • System integrators and OEMs inheriting or maintaining PLC projects
  • Automation engineering teams and TIA Portal programmers
  • Anyone doing revamping who needs to understand an existing plant
  • Anyone auditing or doing due diligence on third-party PLC code
