Profibus wireless makes for Winter Olympic stardom - By N.L. Belardes
I love hearing about how industrial automation is exhibited in real world settings. You never know how some little wireless or protocol-driven gadget might just be powering a highly anticipated world event like the Winter Olympics. Of course I just wanted to learn more about wireless Profibus. So I sent Thomas Schildknecht an email asking him to explain some of the differences between DATAEAGLE and ProSoft Technology's wireless Profibus communications products. He sent me a nice letter with accompanying photos. I think you will all be enlightened as to not only what DATAEAGLE does, but as to how they integrate into real world settings, including the Winter Olympics, factories, and more. Keep in mind I can't read German. There are a few call-outs in the photos. But I can't read them:
My company was founded 1981. In 2006 we celebrate our 25 year jubilee.
Since 1993 we have developed and sold radio communications for industrial automation with the brand name DATAEAGLE. We use every interface like Ethernet, Profibus, Profisafe, Modbus, MPI etc., and every radio technology like WLAN, Bluetooth, DECT and many others.
The DATAEAGLE family now has about 30 family members for different applications. DATAEAGLE 2000 is 1:1 similar to the module ProSoft Technology has to offer. We used it in about 500 applications like Airbus A380 production, Volkswagen motor production, DaimlerChyrsler Cockpit production. The radio modem uses Profibus or Siemens MPI interface for data exchange. But this solution is not a transparent radio Profibus; we call it postbox princip. One PLC sends data to the radio postbox and one or more PLC receives this data in incoming postbox; same prinzip in both directions.
The different is our DATAEAGLE 3002. This is a real transparent wireless Profibus router. We tunnel every Profibus frame through the radio channel. This process has to be done very quick, cyclic with very high availability of the radio channel. 3002 runs transparent with 1.5MBit profibus speed with data exchange times of about 20ms. Only with this principle is it possible to build closed servo loops with a radio communication.
The high-end is ProfiSafe on Profibus base. ProfiSafe uses normal Profibus frames for realizing safety functions. Because our DATAEAGLE 3002 is real transparent like a cable it is possible to build a ProfiSafe connection by radio to integrate safety functions like security stop in skicabines. We built such a network in an Olympic Ski jumping stadium in Courchevel/France oder Vehicular to SacreCoeur on Montmatre/Paris.
It's important to point out such security measures as those regarding Profibus wireless. I am finding, if integrated correctly, Profibus wireless can be even more secure than localized hotspot radios. Of course, integrating both would make for a fine network too. In Europe, whichever product you choose, make sure you just go wireless. It’s the future and present of automation... Thanks to Thomas for his educational letter. I hope to hear more stories from DATAEAGLE in the near future. But watch out Europe, ProSoft Technology is on-hand with their own wireless products that are sure to fire up a few Olympic Villages...
