Softnet PN-IO Linux : Siemens Develops PC-based Profinet IO Software Controller for Linux Systems

03.06.2008
With the “Softnet PN-IO Linux” software controller from Siemens, it is possible to set up open control solutions on standard PC hardware. These solutions can then be used for a wide variety of applications.

Up to 64 I/O devices can be connected to the controller; additional communication hardware is not necessary. An inexpensive link-up to field units in industrial Ethernet networks is thus available to the user. Operation of the devices via wireless LAN is also possible.

Linux systems are becoming increasingly popular in the area of industrial automation, whereby inexpensive PC-based solutions are especially attractive to machine and plant operators. The Softnet PN-IO Linux software controller developed by Siemens now makes it possible to control distributed field devices via Profinet (PN) with standard PC hardware such as the “Simatic Microbox PC”.

The computer functions as a PN I/O controller. Up to 64 devices can be controlled at the same time and, for each device, 1,440 bytes are available in the input and output area. The update time in 100 Mbit full duplex mode is between eight milliseconds (16 connected field devices) and 32 milliseconds (64 connected field devices). For devices linked-up via WLAN, the update time is higher by a factor of approximately four.

The IO devices are configured with the standard tools STEP 7 or NCM PC. PN-IO Base serves as the programming interface. The structure of this C/C++ interface is comparable with the DP-Base interface, a component of the Softnet Profibus DP product. This considerably simplifies porting from existing Profibus DP master applications to PN IO controller applications. Softnet PN-IO Linux can run on open PC architectures. The Linux systems can therefore also be used for other tasks. For example, they can be used as a web server or gateway as well as for visualization or data collection.

The Siemens Industry Sector (Erlangen, Germany) is the world's leading supplier of production, transportation and building systems. Integrated hardware and software technologies combined with comprehensive industry-specific solutions enable Siemens to enhance the productivity and efficiency of its customers in industry and infrastructure. The Sector comprises six Divisions: Building Technologies, Industry Automation, Industry Solutions, Mobility, Drive Technologies and Osram. In fiscal 2007 (ended September 30), Siemens Industry generated sales of approximately EUR40 billion (pro forma, unconsolidated) with around 209,000 employees worldwide.

With the business activities of Siemens VAI Metal Technologies, (Linz, Austria), Siemens Water Technologies (Warrendale, Pa., U.S.A.), and Industry Technologies, (Erlangen, Germany), the Siemens Industry Solutions Division (Erlangen, Germany) is one of the world's leading solution and service providers for industrial and infrastructure facilities. Using its own products, systems and process technologies, Industry Solutions develops and builds plants for end customers, commissions them and provides support during their entire life cycle.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
