PROFIBUS Trade Organization Announces PROFInet IRT Soon To Be Available For High-End Motion Control Applications
Scottsdale, AZ–May 15, 2004–The PROFIBUS Trade Organization (PTO) has announced significant progress toward the release of PROFInet Isochronous Real Time (IRT), the real time PROFInet extension for high performance motion control applications. This extension will complement the existing PROFInet Soft Real Time (SRT) announced in October 2003 for general automation applications.

The new extension will be available within 18 months and will deliver 1 msec synchronization for over 150 axes of control. PROFInet IRT will be more powerful than any currently available real time solution, yet fully compatible with TCP/IP protocols and Ethernet PHY layers. PROFInet IRT will work with any Ethernet TCP/IP network without restriction or limitation.

PROFIBUS International has made significant progress on the IRT extension based on requirements initiated and now documented in white papers jointly prepared by Beckhoff, Bosch-Rexroth, Danfoss, ifak, SEW, and Siemens. The schedule for IRT development is as follows: by mid-2004, the PROFIdrive V3.1 profile will be adopted and engineering and test/certification items finalized. By 4th Quarter 2004, pilot devices will be completed. Finished products are expected to be available by mid-2005.

PROFInet IRT will use next generation switching technology with real time ASIC switches for implementing PROFInet IRT in products quickly and easily, so additional switches will not be required. The onboard ASIC switches include two hardware options currently under development. Designed to be embedded in field devices, the ASICs provide either 2-port or 4-port Ethernet switching capability. For ASIC chip specifications visit us.profibus.com/ertec/html.

In addition, the ASIC switch offers the possibility to build interrupt-free redundant solutions for complex applications at very low additional cost. The objective includes porting the PROFIBUS motion control profile largely unchanged to PROFInet as an important contribution to protecting existing PROFIBUS investments.

The currently available PROFInet real time extension, PROFInet SRT (Soft Real Time), provides cycle times of 5 to 10 msec to satisfy the demands of factory automation. It is fully compatible with the TCP/IP Ethernet protocol and brings the industry's first real time solution to Ethernet users. The run time software is available at www.profibus.com

PROFInet is a modern standard for distributed automation standards and is based on Ethernet. It integrates existing fieldbus systems, specifically PROFIBUS, simply and without change. The use of established Ethernet-based IT technologies allows the connection of the automation/plant level with the corporate management level, including the direct exchangeability of order and production data. Internet connectivity can make it possible to initiate orders and carry out remote servicing and maintenance measures.

The PROFIBUS Trade Organization (PTO) is a non-profit corporation working to enhance the PROFIBUS and PROFInet standards while educating and assisting device manufacturers throughout North and South America on the latest extensions and conformance tests associated with PROFIBUS and PROFInet.
