Routed by tia-openness-roadmap. C# Openness implementation of import/export and round-trip engineering: XML, SimaticML, AML, CAx, choosing between file-based exchange and direct object-model editing, bulk import/export, folder structure planning, overwrite behavior, and object-specific import/export compositions.

tia-import-export

Scope

Import/export strategy and round-trip design — full C# Openness implementation.

When the roadmap routes here, the entire solution is C#. Do not mix with Python wrapper calls.

Use this skill for

choosing direct object edits vs import/export
XML / SimaticML / AML / CAx strategy
bulk engineering changes
export granularity
folder-structure planning
overwrite behavior
project / HMI / PLC / library round-trip workflows
object-specific import/export compositions
mixed import + low-level object-model editing

Execution pattern

identify target object class and Openness composition
identify exchange format (SimaticML, AML, XML)
decide file-based vs direct-edit approach
define source root / target root / overwrite / structure
use Openness import/export services on the correct composition
compile relevant hardware/software after import
validate consistency state
