Configuration Notes:
With the new SIMATIC NET CD Edition 2006 you get a new version of the Custom interface for .NET (Runtime Callable Wrapper (RCW), OPCRcw.Da, OPCRcw.Comn) from the OPC Foundation. If you haven't used a local copy of the previous .NET-RCWs in your application, you must recompile your program to be able to use it with the SIMATIC NET CD Edition 2006.

In the manual entitled "Industrial Communication with PG/PC" in Entry ID 2044387, the Runtime Callable Wrapper is described in section 3.1.5.
