Design of a distributed off-line-interpolation-CNC based on SERCOS interface

Aiming at the rigorous requirement for the field-bus in off-line-interpolation-CNC,it puts forward a kind of OLICNC system which based on Serial Real-time Communication Specification,It also discussed the control principle in detail based on the periodically synchronous mechanism of the SERCOS,Also based on the Embedded system platform it gave out the hardware and software design of the master controller and the smart driver controller for this new OLICNC method.
