The reusable modules also reduce the effort for follow-up projects.Įngineering tools for diagnosis and simulation as well as for parameterizing simple or complex control loops are available as further options. This type of structured programming increases the clarity and simplifies z. The linchpin of all operations here is an accumulator that can work with any data type.Īll forms of representation have in common that program parts are created in so-called functions (without state storage) and function blocks (with state storage). All other programming tools are graphic programming interfaces. Together with SCL, it belongs to the text-based programming languages.

Programs in instruction lists correspond more to classic assembler programming.

S7 HiGraph, graphic programming using state graphs.

S7-Graph (graphically programmable sequential function chart ).

S7 SCL (Structured Control Language) Structured text - a structured high-level language.

The following options (engineering tools) conforming to EN 61131-3 are available:

IL - A n w eisungs l iste, also English as STL ( St atement L is) denotes.

LAD - Ko ntakt p lan (English LD or LAD for La dder D iagram).

FBS - F unction b Austein s PRACHE (formerly FBD function chart).

The basic version of STEP 7 masters the following programming languages standardized in accordance with DIN EN 61131-3 :
