packml

ROS 2 control, Gazebo digital twin and Arduino firmware for a belt laser-marking machine with pneumatic cutting, touchscreen UI, vision QA (YOLO) and OEE

MQTT simulator that fills a Unified Namespace with sheet metal shop data (22 machines, 3 sites, ISA-95, PackML). For UNS demos and training.

Virtual commissioning of a packaging cell: IEC 61131-3 Structured Text on a CODESYS runtime driving a simulated plant over Modbus TCP, a PackML state model, a hazard-to-test traceability gate that fails the build on a gap, and a signed and encrypted OPC UA interface.

Exchange standard for an automated cell: PackML states, 47 tags from one template, OPC UA virtual PLC, MES orders and results with JSON Schemas, supervision screens and SQL historian. Tested end to end, including lost acknowledgements.
