{"id":"cip-motion","model_id":"CIP Motion","name":"ODVA CIP Motion","summary":"CIP Motion is a motion-control profile for EtherNet/IP that defines drive-control extensions for servo and variable-speed drives. It supports torque, velocity, and position control, drive configuration, status, and diagnostics, and unicast or multicast communication. It uses synchronized end-device clocks and time-stamped messages so cyclic motion data can tolerate jitter on standard Ethernet.","study_notes":["CIP Motion is an application profile under EtherNet/IP; it defines drive-control extensions rather than a separate physical network.","Profile functions include torque, velocity, or position control of servo and variable-speed drives, plus drive configuration, status, and diagnostics.","Communications include unicast control-to-drive and multicast peer-to-peer messages; multicast supports position and velocity synchronization across drives controlled by multiple distributed controllers.","Centralized and distributed motion control are both supported, with a common application interface for general-purpose and motion drives.","CIP Sync is ODVA's IEEE-1588-compliant precision clock synchronization and is mapped into the CIP object model.","The document cites less than 1 µs jitter for cyclic data as necessary for precise speed or position control and states clock synchronization better than 200 ns can be achieved.","Time-stamped messages and synchronized end-device clocks reduce the effect of jitter in message receipt time.","CIP Motion runs on standard unmodified Ethernet and is compatible with star and linear topologies.","The network does not need scheduling; packet size and content can change dynamically, including status or command data and drive operating mode changes.","Performance upgrades to 1 Gbit/s and 10 Gbit/s are described as easy for users and device suppliers."],"safety_notes":[],"sources":[{"url":"https://www.odva.org/technology-standards/distinct-cip-services/cip-motion/","title":"CIP Motion™ | Common Industrial Protocol | ODVA Technologies","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":3,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"protocol","spec":{"transports":["tcp","ethernet_l2"],"architecture":"producer_consumer","encoding":"binary","default_ports":[],"data_types":[],"standard_body":"ODVA","standard_ref":"IEEE 802.3","related":["ethernet-ip"]},"url":"https://machineschema.com/protocol/cip-motion","license":"https://creativecommons.org/licenses/by/4.0/"}
