Abstract
A system that includes a position measuring device, a processing unit, a first data channel connecting the position measuring device to the processing unit and for transmitting data from the position measuring device to the processing unit and a second data channel connecting the position measuring device to the processing unit and for transmitting data from the processing unit to the position measuring device. Serial data transmission between the position measuring device and the processing unit is based on ethernet physics, wherein it is assured that a pickup of position data in the position measuring device always takes place at defined times and with the least possible chronological inexactness.
