RTS launches IEEE 1588 Precision Time Protocol for Windows


Ravensburg, Germany – Real-Time Systems GmbH (RTS) has announced its IEEE 1588 stack for all versions of Microsoft Windows. The RTS IEEE 1588 software is a full Ordinary Clock implementation of versions 1 and 2 of the standard that allows highly-accurate synchronization of distributed real-time clocks over standard Ethernet.

The RTS IEEE 1588 software makes it possible to achieve a maximum jitter of about 3 microseconds on a regular Windows PC with the widely available Intel 82574L network adapter. The IEEE 1588 clock in the Intel chip can be accessed through an API, and the Windows system time can be synchronized automatically to the Intel chip.

The RTS IEEE 1588 Ordinary Clock software stack incorporates the full specification and functionality of the Precision Clock Synchronization Protocol for Networked Measurement and Control Systems (PTP) 2002 and 2008. Through PTP, multiple devices are automatically synchronized with the most accurate clock found on the network. During operation and after initial synchronization, the PTP real-time clocks are constantly adjusted by exchanging timing messages. The RTS implementation uses statistical techniques to further reduce residual fluctuations. Because the RTS IEEE 1588 protocol stack supports the PTP hot-pluggable functionality requirement, devices may join or leave the network at any time.

The software is simple, provides a graphical user interface, is administration free and requires minimal resources regarding host components or networks. The RTS IEEE 1588 stack includes all servo algorithms, regulators, filters, PTP-Clock based on hardware timer and direct Timer access. The simple Windows install package and GUI makes using the Real-Time Systems solution easy even for administrators without any special knowledge about the operating system or programming skills.

The Intel 82574L is an Intel Gigabit Network chip with IEEE 1588 support, also available on many inexpensive PCI and PCI Express network cards. Important to most customers is the fact that this chip is found on the Intel Embedded Roadmap with a long term availability of minimum seven years guaranteed.

“With the Intel 82574L there is finally an Off-the-shelf network adapter available for your regular Windows PC, providing hardware time stamping as well as a real-time clock”, says Gerd Lammers, President and CEO of Real-Time Systems GmbH. “Without IEEE 1588 supported in hardware, a non-deterministic operating system like Windows 7 could otherwise not be synchronized accurately.”

Real-Time Systems GmbH, a Microsoft Embedded Silver Partner and a member of the Intel Embedded Alliance on the affiliate level, is expecting wide use of this solution in the medical, financial, industrial automation, defense, aerospace, and test and measurement markets.

The Real-Time Systems PTP solution is also available for a variety of other platforms such as ARM and PPC, and for many operating systems including VxWorks, QNX Neutrino, Linux or ThreadX.

The RTS IEEE 1588 Windows solution is available now. The product is priced starting at US $399.
