The CIP TechnologyCIP Object Model CIP is a strictly objectorientedprotocol, at the upper layers. EachCIP object has attributes (data), services(commands), connections, and behaviors(relationship between attribute values andservices). CIP includes an extensive objectlibrary to support general purpose networkcommunications, network services such as filetransfer, and typical automation functions suchas analog and digital input/output devices, HMI,motion control, and position feedback.ApplicationobjectsAssemblyobjectsI/OParameterobjectExplicitmessageConnection manager orconnection objectMessagerouterIdentityobjectOptionalRequiredNetworkspecific linkobject(s)To provide interoperability, the same object, orgroups of objects, implemented in two or moredevices behaves identically from device todevice. A grouping of objects used in a device isreferred to as that device's "Object Model." TheObject Model in CIP is based on the producerconsumercommunication model which canprovide more efficient use of network resourcesthan a source-destination model by allowing theexchange of application information between asending device (e.g., the producer) and manyreceiving devices (e.g., the consumers) withoutrequiring data to be transmitted multiple timesby a single source to multiple destinations.CIP networkDevice Profiles In order to provide furtherinteroperability in CIP Networks comprised ofdevices from multiple vendors, CIP definesstandard grouping of objects as "Device Profiles."In addition to the set of objects implemented inthe device, Device Profiles specify configurationoptions and I/O data formats. Devices thatimplement one of the standard Device Profileswill respond to all the same commands and willhave the same network behavior as otherdevices that follow that same profile.The CIP Application Coverage forSafety, Synchronization and MotionCIP Sync (Synchronization) CIP Sync is a timesynchronization extension to CIP, based on therecent IEEE-1588 standard – Precision ClockSynchronization Protocol for NetworkedMeasurement and Control Systems – providingthe increased control coordination needed forsequencing demanding events recording,distributed motion control and other highlydistributed applications where absolute timesynchronizationof devices is vital.CIP Motion (Real-time, Deterministic MultiaxisMotion Control) CIP Motion is an extension toEtherNet/IP that allows integration of fielddevices and motion drives on the same network,eliminating the need for a separate motionoptimized network. This provides lower systemcost, improved system performance, and greatlyreduced system complexity.CIP Safety (Functional Safety) CIP Safetyprovides the ability to mix safety devices andstandard devices on the same network or wirefor seamless integration and increased flexibility.The safety protocol provides fail-safecommunication between nodes such as safetyI/O blocks, safety interlock switches, safety lightcurtains and safety PLCs in safety applications upto Safety Integrity Level (SIL) 3 according to IEC61508 standards.

The CIP AdvantageCommon network application layers are the key to advanced communication and truenetwork integration. The Common Industrial Protocol (CIP), which is managed jointly byODVA and ControlNet International, allows complete integration of control with information,multiple CIP Networks and Internet technologies. Built on a single, media-independentplatform that provides seamless communication from the plant floor through the enterprisewith a scalable and coherent architecture, CIP allows companies to integrate I/O control,device configuration and data collection across multiple networks. This ultimately helpsminimize engineering and installation time and costs while maximizing ROI.• Comprehensive suite of messages andservices for manufacturing automationprovides functionality needed forcontrol, configuration, information,safety, synchronization and motion.• Producer-consumer architecture allowsefficient use of network bandwidth.• Seamless bridging and routing allowstopology options for networkarchitectures without having to programor configure intermediate devices.• Device profiles provide commonapplication interface.• Conformance practice helps to ensureinteroperable, multi-vendor systems.• Specification management andenhancement process promotes stable,open, and expanding networktechnologiesDeviceNet, DeviceNet Safety, CIP, CIP Motion,CompoNet, CIP Safety and CIP Sync are trademarks ofODVA.
