With SIMATIC AX, Barmag achieved a highly modularized and standardized codebase that enables efficient reuse across machine variants without starting from scratch for each project. Unit testing and step-by-step offline debugging allow engineers to validate code at their desks before hardware is available, significantly improving quality and reducing errors. Git-based version management enables multiple engineers to collaborate on the same codebase simultaneously, with full traceability of changes and faster onboarding of new team members. Automated CI pipelines handle recurring build tasks, freeing developers to focus entirely on coding while maintaining consistently high software quality.
