Chinas is very large and they export a lot of electronic products. It is however a rather new phenomen, Shenzen was the first exprimental economic zone opened in 1980, the area is a little bit larger than the "county" or similar there I grow up in countryside and in 1980 I think population was similar around 30 000 but right now there is more than 10 million people. The population growth in the pearl river delta have been insane and economy for Guangdong province have grown more than 100 times. > said this last month I wanted to try powerlink and Lcnc together to be able > to observe the performance of a system with both running instances. ... Requirement on performance is not very high. It is almost always need for between three and six axis which will be around 6*32bits = 192 bits of payload each period, IO may be slower. A more reasonable amount is 8*64bits @ 1kHz = 512bit @ 1kHz = 512kbit/s of payload at 1kHz. All counted full duplex. With control loop at linuxcnc computer there and one driver card for each motor there would however be a need in the range of 2*3*1kHz to 2*8*1kHz messages per second. Or (1+3)*1kHz to (1+8)*1kHz if multi casting is used.
