A white paper was issued comparing DPWS and OPC‐UA.  Based  on  this  white  paper,  and  on  the  agreement  between  Schneider,  Siemens  and  ABB  to  find  a  common  interoperable  solution  (also  supported  by  SAP),  Schneider  got  in  touch  with  the  OPC  Foundation  in  order  to  explore  the  feasibility  of  this  common  solution.  

Schneider  looked  at  possible  standardization  paths  through  IEC65E,  and  concluded  that  it  will  be  possible  to  push  such  a  solution  through  this  committee  when  a  detailed  specification  will  be  available.  Schneider  is  in  charge  of  writing  this  specification,  and  to  discuss  it  and  validate  it  with  SOCRADES  partners.
