ODVA Reorganizes and Enhances Common Industrial Protocol And CIP™ Networks Specifications

June 292004
Ann Arbor, Mich., June 28, 2004 — ODVA today announced the reorganization of its DeviceNet™ specification, as well as the release of several significant new specification enhancements for DeviceNet™ and EtherNet/IP™. This reorganization aligns the DeviceNet specification with the EtherNet/IP specification, and facilitates specification ease of use by users of both networks. Scheduled for publication by Q4 2004, the specification will also include enhancements that provide users with new networking functionality to help increase manufacturing productivity.

Under the new organization, the Common Industrial Protocol (CIP™)—which is used by all CIP networks—will be defined in one volume, while the specific network adaptations of CIP will be covered in separate volumes. CIP, which is managed
jointly by ODVA and ControlNet International, allows complete integration of control with information and Internet technologies. Built on a media-independent platform, CIP provides seamless communication from the plant floor through the enterprise, combined with scalable network architecture, and allows companies to integrate I/O control, device configuration and data collection across multiple networks.

The publication of CIP network specifications in this two-volume format will clearly delineate the identical upper layer protocol used by all CIP networks and the differences in implementation needed to adapt CIP to specific networks. ControlNet International has also decided to follow this publication format for its ControlNet specification, and is expected to announce its publication in the same two-volume format in upcoming months.

“Publishing CIP network specifications in a two-volume format will help educate both users and device manufacturers about the inherent universality of the Common Industrial Protocol and the networks on which it resides” said Katherine Voss, Executive Director of ODVA. “Armed with this knowledge, vendors will be able to provide users with the ability to choose the best CIP network for their applications while maintaining interoperability of devices, networks and control systems. The result for users will be improved payback on automation investments through reduced cost and time for engineering, installation, training and maintenance, along with more informed decision making from their automation assets that is possible only with a network architecture that allows the plant floor to be integrated seamlessly with the enterprise.”

Along with the first publication of the reorganized DeviceNet specification, new enhancements to the CIP, DeviceNet and EtherNet/IP specifications will be available, including:

  • New encoder capabilities extend the application coverage of CIP networks to include standard profiles and objects for a variety of encoding devices, including single-turn, multi-turn and linear, as well as velocity, acceleration and CAM functions;
  • Device self-documentation provides a transparent means of accessing the Electronic Data Sheet (EDS) that can be stored within each device. By having instant access to device parameters— including model number, configuration information and size or other rating— manufacturers can reduce production downtime and improve diagnostics;
  • QuickConnect over DeviceNet allows users to establish a connection immediately following the application of power to selected devices on the network. The QuickConnect feature—which is crucial in applications requiring quick device changeovers such as robot end-of-arm tooling—minimizes production changeover time by allowing one group of nodes to replace another without requiring the entire network to be powered down;
  • A variety of new semiconductor industry related enhancements, including expanded application coverage for ion gauge devices;
  • M12 connector option for EtherNet/IP provides a pin-and-socket connector option for users who need an IP67-rated connector in a small form factor;
  • Increased flexibility to configure the data link layer of EtherNet/IP adds the ability to override automatienabling users to set these values in the software during network commissioning.

    “The enthusiasm of ODVA's members to continue adding new features and functionality to CIP, DeviceNet and EtherNet/IP through the specification enhancement process reflects the vitality of the CIP networks and suggests that the recent surge in the adoption of CIP networks is indicative of future industry trends,” said Voss.
