{"id":"controlnet","model_id":"ControlNet","name":"ControlNet","summary":"ControlNet is a CIP network used for deterministic transport of time-critical I/O and peer-to-peer interlocks. It supports trunkline-dropline, star and tree topologies and can use redundant communication or intrinsically safe hardware options. ControlNet uses the Common Industrial Protocol for its upper layers and follows the OSI seven-layer model.","study_notes":["ControlNet uses CIP for its upper protocol layers.","ControlNet follows the OSI seven-layer model.","Topology options include trunkline-dropline, star and tree.","Redundant network communication is available.","The document references 'Technology Overview Series: ControlNet' for a comprehensive overview.","CIP is described as media-independent and covers control, safety, energy, synchronization & motion, information and network management."],"safety_notes":["Hardware options are offered for applications requiring intrinsically safe hardware."],"sources":[{"url":"https://www.odva.org/technology-standards/other-technologies/controlnet/","title":"ControlNet® | ODVA Technologies | Technology & Standards","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":1,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"protocol","spec":{"transports":["other"],"architecture":"producer_consumer","encoding":"binary","default_ports":[],"data_types":[],"related":[]},"url":"https://machineschema.com/protocol/controlnet","license":"https://creativecommons.org/licenses/by/4.0/"}
