PLC Software Migration & Compatibility Tool

At INEL, I worked on C#/.NET software for industrial production systems, including communication with PLC-controlled machinery and processing of machine data.

A key task was migrating PLC specification and instruction documents stored as XML across incompatible generations of the company’s software. The formats, schemas, annotations, and data structures had changed significantly, and there was no direct conversion path for every document.

Built an internal migration and conversion tool for legacy PLC documents

Automated retrieval of the required historical software versions from Git

Compiled and inspected version-specific types to understand the differences between generations

Implemented conversion logic and compatibility handling for complex XML structures and serialisation formats

Reverse-engineered gaps where no direct mapping existed

Worked on serialisation and data-processing optimisation

Built internal tooling for application translation management

I also diagnosed production issues across the application, machine, and PLC layers. That meant tracing behaviour through software, machine communication, and industrial control systems rather than treating the application in isolation.
