The Basic Languages LAD, FBD, STL

Topic of the demonstration system
SIMATIC Software is the integrated system environment for all SIMATIC systems and offers the user the perfect tool for each task and each project phase in order to optimize his engineering workflow. The basic software STEP 7 comprises the three languages LAD, FBD and STL which are in accordance with the IEC standard and which are learnable easily and intuitively. The three languages all possess an extensive stock of functions which can be applied to the entire range of SIMATIC Controllers.

Contents of the demonstration system
This demonstration system presents the three basic languages LAD - Ladder Diagram, FBD - Function Block Diagram and STL - Statement List. In doing so, we show the properties and possibilities provided by the various tools of the SIMATIC Manager for the implementation of a user program in the three language variants. In the form of animated graphical sequences, the module demonstrates

• tthe customer benefits that each language and tool contributes in its respective project phase,
• the underlying functional principles and
• live configuration sequences with the editor functions of the SIMATIC Manager.

Presentation of an animated demonstration system
The following properties are contained in all technically-oriented demonstration systems:

• All graphical 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.
