Controller with high-speed isochronous Profinet communication

28.03.2008
A wide range of Simatic controllers now communicates via high-speed IRT (Isochronous Realtime) Profinet.

The Siemens Industry Automation Division has therefore equipped the devices with the relevant interfaces. The CPU 319-3 PN/DP for the Simatic S7-300, the Profinet CPUs of the Simatic S7-400, a new Profinet CPU for the ET 200S distributed I/O system and the new Simatic S7-mEC embedded controller have IRT capability.


IRT is especially suitable for large machines and equipment with short updating times and a large number of nodes in a linear arrangement. IRT is also advantageous when automation data and a high volume of standard Ethernet data, for example via TCP/IP, have to be transferred within a network.

IRT Profinet divides the medium bandwidth into two intervals. One of them is reserved for the fast and deterministic transfer of automation data while the other is used for standard Ethernet data which are not time-critical. The FSU (Fast Start Up) function enables Profinet IO devices connected to the network to power up within one second.

This is extremely useful in robot applications, for example, where rapid re-tooling is necessary. The integrated web server provides user-friendly diagnostic functions, for example for the topology of the entire network or the status of the connected Profinet and Profibus field devices. Important web information, such as variable status and tables as well as the status of field devices, is updated automatically.

Im Focus: Happy hour for time-resolved crystallography

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.

The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.

Im Focus: Modular OLED light strips

At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.

Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often...

Im Focus: The working of a molecular string phone

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.

This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.

Im Focus: Milestones on the Way to the Nuclear Clock

Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.

If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...
