Finally we’ve managed to get a peek at the IMS Research report on the 2009 World Market for Industrial Ethernet. It highlights that standard Ethernet TCP/IP accounts for nearly two thirds of all Ethernet nodes used in industrial automation, with the remaining third being split among numerous protocol variants.
Let’s look at that ‘interesting’ third first – we say interesting, because these are the protocols that always dominate the ‘Ethernet wars’ style headlines. The report reckons that EtherNet/IP has 32.8%, Profinet 28.1%, Modbus TCP/IP 18.1%, Ethernet Powerlink 5.4%, EtherCAT 4.7%, and the remainder made up by the likes of SERCOS, HSE, CC-Link IE and others.
But surely what’s really interesting is that, even combined, all these highly vocal parties account for just a third of the overall market, with standard Ethernet TCP/IP making up the remaining two thirds. Will the picture stay the same? IMS is somewhat cryptic. It says that the overall market for industrial Ethernet networking installations will grow by over 10% a year from 2011. Meanwhile, new installations of dedicated industrial variants will grow by 40% from 2008 to 2013. Putting the figures like that makes it hard to draw a comparison. If your maths is better than mine, let me know.
I got a virus in my computer, the virus randomly poops up websties when im online, or when i click on a link fro example a link from somthing i googled it send me to this ramdom pages. My internet explorer also keeps on saying that there was an error so it keeps shutting down. I already scaned my compuer several times and all it catches is a tracking cookie, It never picks up any virus. Also one of the sities that popped up was about norton popping up sites and had people’s comments of how annoying that was. It was a Norton site(wich pooped up too) I dont know if that is even relevant to this. Does anyone know what i can do about this, or how i could take the virus off? i dont wanna have to buy another antivirus? Please Help, my computer is even slower now and the sites are super annoying i cant even search anything either. Thanks guys I appreciate it santoramaa
