SIMATIC STEP 7 Basic (TIA Portal)

The Engineering Software for the Basic Controller SIMATIC S7-1200

SIMATIC STEP 7 Basic (TIA Portal) is a price-optimized subset of STEP 7 Professional controller software in the TIA Portal that can be used for engineering SIMATIC S7-1200 Basic Controllers and configuration of SIMATIC HMI Basic Panels, as WinCC Basic is part of the software package.

SIMATIC STEP 7 Basic offers the same benefits as STEP 7 Professional engineering software thanks to its integration into the TIA Portal engineering framework, e.g. direct online diagnostics, easy creation of technology objects and also the library concept for time-saving, efficient work and programming components reuse.

STEP 7 Basic (TIA Portal) supports the IEC programming languages LAD (Ladder Diagram) as well as FBD (Function Block Diagram) and SCL (structured text).
