• Optimized data block access to S7-1500
• Open standardization of the addressing using logical names for objects from an automation component or an automation system
• Supports STEP 7 symbols
• Efficient data transfer from a process component to an application for further processing
• One client application can use several servers simultaneously
• Simultaneous execution of more than one client is possible on one OPC server
• Communication protocols can be used in parallel by means of the multiplexer function
• Interfaces
  • "Custom Interface“ for high-performance C++/NET applications
  • "Automation Interface" for easily created Visual Basic applications (or similar)
  • XML DA interface;
    Data access to S7 CPUs is therefore possible over the Internet.
  • OCX Data Control or .NET Data Control for direct integration in Windows applications that support COM/DCOM

Comparison of conventional client/server architecture with an OPC architecture

Configuration

The communication parameters are configured entirely using the tools of the installed SIMATIC NET software
