Totally Integrated Automation
In addition to an HMI system such as WinCC flexible, a complete automation solution includes other
components, such as controller, process bus and periphery. WinCC flexible offers a particularly
extensive integration with components from the SIMATIC product family:
• Integrated configuring and programming
• Integrated data management
• Integrated communication
Integration in SIMATIC STEP 7
Process variables are the connecting link for communication between controller and the HMI system.
Without the advantages of Totally Integrated Automation, you have to define each variable twice:
once for the controller, and once for the HMI system.
Integrating SIMATIC STEP7 into the configuration interface lowers error frequency and configuring
effort. While you are configuring, you are directly accessing the STEP7 symbol table and the
communication settings:
- The STEP7 symbol table includes the data point definitions (for example, addresses or data
types) that were specified when you generated the control program.
- The communication settings contain the bus addresses and the control protocols
- Communication is set with NetPro, for example.
