Task description:
This documentation shows how WinCC and STEP 7 with example blocks is used for the solution of an technological automation task.

The sensors (binary and analog signals) and actuators (valves, motors) of a plant system represent the basis of each automation project. In the standard delivery of STEP 7 and WinCC, there are no technological blocks contained to implement basic automation.

At this point, this application provides a remedy. It makes useful blocks available for WinCC and STEP 7.
The application supports S7-300 and S7-400 systems.

Solution:
In the example project, the following example blocks for WinCC and STEP 7 are included:

• Digital and analog blocks
• Motor block
• Valve block
• SIMOCODE blocks
• Micromaster and SINAMICS blocks
• SIPART PS2 PA positioner blocks
• Controller block
• PC diagnosis display

The above-mentioned blocks have been developed within the framework of an example project. You can find it at the end of this page.

The documentation describes how the technological blocks are called and interconnected in STEP 7 and WinCC. For this purpose, an example system has been created, which consists of several binary and analog values, valves and motors. The example project illustrates the interconnection of the technological blocks (basic automation). Some higher-level automation functions (two-position or PID control) are configured as well.

The following illustration displays the most important components of the solution.
