SERCOS interface
History
 1985: Working Group by VDW (Association of German Machine
Tool Builders) and ZVEI (Association of Electrotechnical Industry)
releases an updated version of the analogue +/- 10V interface and
initiates the definition of a digital drive interface for machine tools
(Working Group „Digital Drive Interface“)
 1989: SERCOS interface having its premiere at EMO in Hannover /
Germany
 1990: Foundation of SERCOS Organization (today: SERCOS
International)
 Original members: ABB, AEG, AMK, Bosch, Indramat, Siemens
