THE COMMONINDUSTRIAL PROTOCOL(CIP TM)1

PUB00122R2 MARCH 2016

ODVA’s four best-in-class networks — EtherNet/IP™, DeviceNet™, ControlNet™ andCompoNet™ — all are linked by one of industrial automation’s most versatile protocols: theCommon Industrial Protocol, known as CIP™. CIP encompasses a comprehensive suite ofmessages and services for the collection of industrial automation applications — control, safety,energy, synchronization & motion, information and network management. CIP allows users tointegrate these applications with enterprise-level Ethernet networks and the Internet. Supportedby hundreds of vendors around the world and truly media-independent, CIP provides users witha unified communication architecture throughout the industrial enterprise. CIP allows users tobenefit today from the many advantages of open networks and protects their existing automation
investments, while providing an extensible and upgradeable communication architecture.

CIP Networks at a GlanceWith media independence comes choice — the ability tochoose the CIP Network best suited for your application.
As a single, media-independent platform that is sharedby a variety of networking technologies, CIP provides theinteroperability and interchangeability that is essential
to open networks and open systems. Four network
adaptations of CIP are available.

ControlNet CIP on CTDMA Technology
ControlNet provides users with the tools to achieve
deterministic, high-speed transport of time-critical I/O
and peer-to-peer interlocks. ControlNet offers a choice oftopology options including trunkline-dropline, star or tree.

Network Adaptations of CIP

DeviceNet CIP on CAN Technology
DeviceNet provides users with a cost-effective network
to distribute and manage simple devices throughout theirarchitecture. DeviceNet uses a trunkline-dropline topology
and has DC power available on the network cable tosimplify installations by providing a single connection
point for network communications and device power up
to 24 Vdc, 8 Amps. QuickConnect functionality allows
devices to be exchanged while the network is running.

CompoNet CIP on TDMA Technology
CompoNet enables users to maximize network throughput
for applications needing to transmit small packets of data
quickly between controllers, sensors and actuators. Its
simple network connector and cabling scheme reduces
overall system cost and time.

Common Industrial Protocol (CIP™)

EtherNet/IP CIP on Ethernet Technology
EtherNet/IP provides users with the network tools to deploy
standard Ethernet technology (IEEE 802.3 combined withthe TCP/IP Suite) for industrial automation applications
while enabling Internet and enterprise connectivity…dataanytime, anywhere. EtherNet/IP offers various topology
options including a conventional star with standard
Ethernet infrastructure devices, or device level ring (DLR)
with EtherNet/IP devices so enabled. QuickConnect™
functionality allows devices to be exchanged while thenetwork is running.

Hardware options are also offered for applications
requiring intrinsically safe hardware. Redundant network
communication is also available.

Comprehensive Application
Coverage in a Single Protocol
Functional Safety
Safety application coverage in CIP provides the ability
to mix safety devices and standard devices on the same
network or wire for seamless integration and increased
flexibility. CIP Safety™ provides fail-safe communication
between nodes such as safety I/O blocks, safety interlock
switches, safety light curtains and safety PLCs in safety
applications up to Safety Integrity Level (SIL) 3 according toIEC 61508 standards. CIP Safety has also been adopted bySercos International.
Energy Optimization
CIP Energy™ provides a family of objects and services
for the optimization of energy usage (OEU™) and allows
scalable implementation in the device, from basic energy
awareness to advanced functions for controlling energy,
aggregation and reporting of energy information or dynamic
demand-response. Further, CIP Energy allows systems
to monitor energy usage and manage energy for efficientconsumption through dynamic control of energy state andanalysis of energy information. Protocol-neutral energy
attributes provide flexibility in the propagation of energy
information via multiple protocols to facilitate e-businessmodels such as capturing energy requirements as a line
item on production bills of material or to implement demandresponse mechanisms for dynamic energy transactions.
Synchronization
Synchronization services in CIP provide the increased
control coordination needed in applications whereabsolute time synchronization is vital to achieve realtime synchronization of distributed intelligent devices andsystems. CIP Sync™ is compliant with the IEEE-1588™
standard and allows synchronization accuracy between
two devices of less than 100 nanoseconds. Real-timesynchronization is achievable over conventional 100Mbps
Ethernet systems with a switch-based architecture.
Distributed Motion Control
Motion application coverage in CIP eliminates the needfor purpose-built motion-optimized networks by allowing
high performance motion control and other devices to be
combined on a single EtherNet/IP network. This results
in a modular and streamlined approach to system designand lowers overall system and training cost. CIP Motion™
achieves real-time deterministic behavior of multiple axes
through a common sense of time, allowing 100 axes to becoordinated with a 1 millisecond network update to all axes.
Clock synchronization between axes of fewer than 100
nanoseconds can be readily achieved, meeting the needsof the most demanding motion control applications.

The Technical Approach to CIP
CIP is a media independent protocol using a producerconsumer communication model, and is a strictly object
oriented protocol at the upper layers. Each CIP object
has attributes (data), services (commands), connections,and behaviors (relationship between attribute values andservices). CIP includes an extensive object library to support
general purpose network communications, network
services such as file transfer, and typical automation
functions such as analog and digital input/output devices,
HMI, motion control, and position feedback. To provide
interoperability, the same object (or group of objects)
implemented in two or more devices behaves identicallyfrom device to device. A grouping of objects used in adevice is referred to as that device’s “Object Model.” TheObject Model in CIP is based on the producer-consumer
communication model, which can provide more efficient useof network resources than a source-destination model by
allowing the exchange of application information between
a sending device (e.g., the producer) and many receiving
devices (e.g., the consumers) without requiring data to betransmitted multiple times by a single source to multiple
destinations. In order to provide further interoperability in
CIP Networks comprised of devices from multiple vendors,
CIP defines a standard grouping of objects as “DeviceProfiles.” In addition to the set of objects implemented inthe device, Device Profiles specify configuration options
and I/O data formats. Devices that implement one of
the standard Device Profiles will respond to all the samecommands and will have the same network behavior asother devices that follow that same profile. CIP also canprovide simple integration of Modbus® devices through useof its native Modbus translation services.

The CIP Advantage
The key to advanced information technology andnetwork integration
CIP’s common application layer allows complete integrationof control with information, multiple CIP Networks
and Internet technologies. Built on a single, mediaindependent platform with a common application layer,
CIP provides seamless communication from the plant
floor through the enterprise with a scalable and coherent
architecture. CIP allows companies to integrate I/O control,
device configuration and data collection across multiple
networks. This ultimately helps minimize engineeringand installation time and costs while maximizing ROI.
