With the SIMATIC NET OPC Server described here, SIMATIC NET offers you a
convenient tool with which your PC applications can write and read process data
and receive notification of process events. 

By creating a project engineering database, you can specify the behavior of the
OPC Server. You then download the project engineering data to the PC station
with NCM PC.

This chapter describes the options available to you when creating the project
engineering data for the OPC server with the NCM PC project engineering tool.
