The S7 Architecture

  • Entry

Realizing the automation task into a structured controller program is significantly facilitated by many properties of the SIMATIC software as well as the firmware of the SIMATIC controller. The basis for creating an efficient program for controlling a plant or production machine is above all the architecture of the SIMATIC CPU and the SIMATIC software.

Here we show you the fundamentals of the program execution system, the user memory model and the SIMATIC variable and block concept. Within the frame of animated graphics, this module presents those properties of the SIMATIC controller and software which support you in the implementation phase of your project.

The following properties are contained in all technically-oriented demonstration systems:

  • All graphic animations are explained by a spoken text which has been read by German, respectively English native professional speakers.
  • The respective sections of the demonstration system can be clicked on by means of navigation elements. You may, for example, repeat any section any time.
  • Continuative links and support pages have been integrated.

The following picture shows the home page of the demonstration system.
