Abstract: The Serial Real-time Communications Standard (SERCOS) interface protocol is the unique international standard applied to numerical controls and drivers, and it has been widely used worldwide. SoftSERCSANS is a type of SERCOS interface evolution, which abstracts the interface at the software level. An overview of background, development and application characteristics of SERCOS communication interface protocol were provided. Working principles and communication phases of the SoftSERCANS were analyzed. Implementation of a numerical controlled open architecture CNC system for a three-axis milling machine based on the SoftSERCANS was discussed. And the outlook for the application of the SoftSERCANS and the impact of this application on CNC market were described. Application of SoftSERCANS will not only improve numerical control technologies but also change production modes of numerical control systems, which will directly lead to market change in this area.
