Bochum, Germany, May 31^st, 2011 - In the year 2010 Ethernet was already used at each second machines, thereof 29% with TCP/IP and 21% with real time Ethernet. According to the planning of the machine-builders the portion of the machines with Ethernet will increase to 72% until 2012. TCP/IP will be used with 35% and real time Ethernet with 37% of the machines. Thus real time Ethernet will grow at an annual rate of 42%.

The Quest Trend Magazine quotes the market shares of the individual real time protocols of Ethernet based on the number of the machine-builders that use these protocols in 2010 resp. will implement these protocols up to 2012. The study covers beyond that the market shares related to the numbers of machines equipped with these protocols.

ProfiNet will be used by 42% of the machine-builders in 2012. So ProfiNet including its three versions, takes the top position.

EtherCat will be behind ProfiNet the most common real time Ethernet protocol with 24% of the machine-builders.

The real time Ethernet protocols Powerlink, Sercos III and Ethernet IP will show market shares from 8% to 10% in 2012 according to the planning of the machine-builders.

Finally the machine-builders allocate VARAN, Modbus and in-house solutions in each case market shares below 5% in 2012.
