ODVA network standards ‘blossom’ in sunny Phoenix
Balmy Phoenix, AZ, was an appropriate venue for ODVA’s recent 2006 CIP Networks Conference & 11th Annual Meeting. Below are the highlights of the four-day conference.
For those unaware, it’s not the same old ODVA versus 1999 with only a DeviceNet focus. Since then its stable has expanded to include:
2005: CIP Safety
2006: CIP Motion
2006: CompoNet; and
2006: CIP Sync
As ODVA enters its 11th year it has 270 members. Looking to the future it also announced a new‘face’ at www.odva.org having:
The ability to search all site elements for improved usability;
The functionality to control when an individual item’s published status expires, so outdated information is automatically removed from view.
The capability to restrict user’s access to private areas, as well as allowing selected users the right to post information to the site; and
The ability to transmit selected data, such as credit card information, by secured encryption.
Standards are ODVA’s largest asset, constituting the vast amount of intellectual property that ODVA has acquired or created over the last decade. The organization expects to continue strengthening and expanding its portfolio of standards. To this end:
ODVA has approved a new participation agreement for SIGs that unifies this agreement for all ODVA Technologies under one document, and will extend this unified approach, in conjunction with ControlNet International, to the Participation Agreement for jSIGs in 2006; and
ODVA has been granted the rights to develop a new network adaptation of CIP based network technology developed by ODVA founding member OMRON. The new network is under development in the‘Project CipNet SA SIG.’ The new network is targeted at applications dominated by simple sensors and actuators. ODVA has named the new adaptation ‘CompoNet.’ CompoNet rounds out the network coverage of CIP and provides ODVA with a complete network story to address the market space served by AS-I and CC-Link LT.
With this new network adaptation of CIP, all CIP networks are members of the unified family of CIP Networks. Furthermore, all CIP networks are complementary, not competitive, to one another, to provide industry with a fully rounded suite of networks with unique advantages for specific applications.
To promote industry awareness, ODVA is sponsoring a variety of outreach activities principally in the areas of trade shows, symposia, and conferences. For vendors it has Ethernet/IP workshops in Europe, North America, China, and Japan.
Additionally, ODVA will recognize and support its members who are part of the group known as‘The CIP Conformity Club.’ It comprises those vendors who are committed to conformance testing. ODVA is committed to add value for these club members by setting an objective of the conformance testing process of fewer problems in the field and increased market demand for conformance tested devices. ODVA will make continuous process improvements in its conformance testing practice that are of maximum value to the Club.
The‘CIP Conformity Club is comprised of those vendors that are committed to conformance testing.
The CIP Conformity Club Initiative’s guiding principles for certification include:
Maintaining vendor-neutrality of the tests;
Providing equivalent test coverage of CIP for all CIP Networks;
Eliminating false positives and false negatives in the testing process; and
Making test results are consistent from test to test, device to device, TSP to TSP.
Supporting the principles are the establishment of the Conformance Authority and the establishment of both a single conformance test jSIG for all CIP networks as well as a project
to develop an unified suite of conformance tests across the complete family of CIP networks.
ODVA-cited major accomplishments included:
1. CIP Sync, comprising:
Time Sync Object;
Links 1588 and PTP;
Key applications: Time stamping, coordinated motion, coordinated output, sequence of events recording, and synchronized actuation.
2. CIP Motion, having:
Passed two key specifications:
i. CIP Motion drive profile; and
ii. Motion Axis Object
Key applications: Family of features, multi-axis, synchronized motion; real-time-Ethernet-coordinated motion, augmented with CIP Sync. Use enables coordinated precision motion control on standard Ethernet.
Announced plans to proceed;
Formed SIG in September;
Developed specification; and
Preparing to release in 2006, currently targeted for second quarter.
2. CIP Safety
Volume 5 published January 2005;
Conformance testing established January 2005;
EtherNet/IP extensions added, only five pages of enhancements;
TÜV certification for SIL 3;
SI safety certification maintained with non-safety devices; and
First products have shipped.
New features in CIP networks include:
Event log, providing a common method for the storage, identification and time stamping of events within devices. It can act as‘chart recorder’ or activity record;
Large forward open, opens a connection for data transfer up to 65K bytes long; and
Identify common events and conditions, establishes standard diagnostic codes for common events that devices might encounter, for example, over temperature, CRC/checksum errors, and power problems.
On the specification development front, ODVA has:
Published two updates to the specifications;
Established a new record of 66 new published Ses;
There are two active SEs in queue; and
The oldest SE is from February 2006/
ODVA outlined its ongoing SE process:
Submittal process review will see incremental specification enhancement processing;
There will be two publication cycles annually with published cut-off dates;
An FTP site will be implemented FTP; and
There will be updated SE and new TDE forms.
The breadth of ODVA’s standards activities is described in the matrix above.
On the support front, ODVA cited:
A major upgrade of the EtherNet/IP installation guide (EtherNet/IP Physical Layer jSIG);
Release of the DeviceNet troubleshooting guide (Automotive SIG);
Creation of sample EtherNet/IP code (EtherNet/IP Implementor workshops-North American tour); and
EZ-EDS: Easy Feature-driven EDS Generator (EtherNet/IP Implementor Workshops-European Tour)
Future major initiatives include:
Release of CompoNet specification;
Implementation of new conformance organization;
Continued SE process improvement
Release of CIP Motion peer to peer functionality; and
Release of FDT Specifications for linkage to CIP.
Potential new technologies that may be encompassed by ODVA standards include:
ODVA notes the ascent of EtherNet/IP, and its‘Game Plan to Win the Industrial Ethernet Wars’ comprises:
Establishing EtherNet/IP as a standard in major industry segments such as semiconductor and automotive industries;
Establishing EtherNet/IP as a standard in China—supporting this achievement with increased ODVA presence in China;
Increasing EtherNet/IP awareness in general;
industry and know-how in the vendor community; and
Boosting the application coverage of EtherNet/IP in key growth areas such as motion and functional safety.
Cisco becomes founding member
ODVA also recently announced that Cisco Systems Inc., a worldwide leader in networking for the Internet and a member of ODVA since 2003, has significantly increased its level of support to the association by becoming one of its founding members. In this role, Cisco will provide broad-based support to ODVA in the development and management of its industrial network technologies, included serving on its Board of Directors and Technical Review Board. Cisco's increased involvement in ODVA will further enhance ODVA's ability to drive open, interoperable and sustainable network standards directed at unifying plant floor automation with factory IT.
“Cisco is committed to bringing Ethernet to the factory floor,” said Scott Westlake, Worldwide Manufacturing Industry director, Cisco Systems. “ODVA’s EtherNet/IP is fully compatible with Cisco's commercial networking technologies and it is the most developed, proven and complete standard industrial Ethernet network available today. Cisco has increased its level of support to ODVA because the association provides an excellent community of leading manufacturers of industrial network technologies with which Cisco can work to develop network standards and interoperability for the manufacturing enterprise, including security, wireless, IP telephony, power over Ethernet and real-time Ethernet.”
Seconding the motion as it were, Steve Eisenbrown, senior vice president, Automation, Control and Information Group, Rockwell Automation said, “Rockwell Automation, an original founding member of ODVA, is committed to the use of standard, unmodified Ethernet to help bridge the gap between IT and automation. EtherNet/IP will greatly benefit from the increased participation of Cisco in ODVA. Combining the resources and expertise of Rockwell Automation and Cisco with ODVA will accelerate the integration of information throughout the enterprise.”
