1.DDE to OPC --suggest you use the Kepware,there is a OPC for DDE driver and it's cheap,about US$800
2. FoxAPI to OPC --Though you can purchase the OPC for Foxapi(not purchase from Foxboro),you still need the NetFoxAPI.
So ,if the EWS is NT,you can use this OPC(a local FoxAPI)
if the EWS is solaris,you need a NetFoxAPI still.
It depend on what platform of your EWS ,NT or Solaris(PW70 or AW51)
