Migrate CODESYS V2 to CODESYS V3

A version change affects software structure, target hardware and interfaces. Required functions are identified separately from legacy project dependencies.

Scope of work

Technical tasks

  • Review libraries and functionality
  • restructure software for V3
  • agree communication and data-point checks

Technical questions

What can be done if legacy PLC project files are missing?

Available documentation, hardware, signals and the required functions are reviewed first. This provides a basis for a testable modernisation scope and a list of open technical points. Recovery of a complete original project is not promised as a standard outcome.

How does a CODESYS migration differ from adding data integration?

Migration transfers or reimplements control software for a new system generation. Data integration makes selected plant values available to other systems. Both tasks may occur in one project, but they have separate interfaces and checks.
