2011 Spring Plugfest of the IEEE 1588 Standard and Technology Forum

The Institut Industrial IT (inIT) of the Ostwestfalen-Lippe University and the Fraunhofer Competence Center Industrial Automation (IOSB-INA) in Lemgo/Germany are hosting an industry plugfest, providing participants the opportunity to perform interoperability testing of devices in compliance with the Precision Time Protocol IEEE 1588 standard. The Precision Time Protocol Interoperability plugfest will take place March 30 – April 1 2011 at the Science-to-Business Center Industrial IT (CIIT) in Lemgo, Germany, which is nearby to the venue of the Hannovermesse 2011.

As use of Ethernet became increasingly widespread in networked measurement and control systems, an alternative to existing protocols was required that could increase the accuracy of clock synchronization while minimizing the cost of implementation. The standard, originally published in 2002, and revised in 2008 as IEEE 1588-2008, allows a variety of industries including telecommunications, industrial automation, power transmission, test and measurement and consumer electronics, to increase timing accuracies, minimize network administration and resources, and adapt to low-cost and low-end devices.

As independent organizations, inIT and Fraunhofer are committed to neutral testing of open standards technology and the lab’s plugfests allow participating companies to test their devices and identify interoperability and performance issues early, speeding go to market time for products. Working together, the participants can decrease research and development and quality assurance expenses, reduce product time to market and drive the industry acceptance of a technology.

During the three days of the plugfest a fixed set of tests will be performed, covering the IEEE 1588 Default Profile, the Power Profile (IEEE C37.238) and the Telecom Profile. In order to separate the different profiles, each of them is getting its own test network. On day 1, the traditional basic configuration and installation is scheduled for the first session, followed by dry-runs of the key test cases to verify that everything works as expected during the formal test runs. On the day 2 and 3, the formal tests are divided into five official test sessions. It is planned to have a showcase session in the afternoon of day 2 (Thursday) to allow interested visitors to meet the plugfest participants and get the opportunity to find out more about IEEE 1588 products and applications.

A. Interoperability
 - Master/ Slave Operation Modes
 - BMCA
 - Sync State Machines

B. Performance
B.1 Sync Accuracy
 - Synchronization Deviation Master to Slave by pps signals
 - Master Changeover
 - Secondary Master takes over due to Primary Master Failure

B.2 Robustness
 - Multicast (Delay Measurements)
 - Unicast (Sync and Delay)

Network Conditions/Degradation
 - Traffic / Bandwidth
 - Topology Changes (Ring Failure)
 - Packet/Connection Loss
 - Other Delay Variations

C. Compliance
The defined tests are currently worked on, they will be published as soon as possible. It is planned to record network traffic and sync performance (using PPS outputs) for each test in order to provide the participating engineers with valuable data for further analysis and improvements after the plugfest has ended.

Test Equipment
- Anritsu MD1230 Network-Generator, Analyzer, Interrupter
- WAN Emulator Packetstorm
- pss-Datenlogger
- FLEXEGEN (OWITA) Delay Generation, Packet Filter, Error Generator
