SIMATIC STEP 7 Safety (TIA Portal)

Option for seamless safety integration

All configuration and programming tools required for generating a safety-oriented program are integrated into the STEP 7 user interface and use a common project structure. Using the SIMATIC STEP 7 Safety Basic or STEP 7 Safety Advanced (TIA Portal) option, you can exploit all the advantages of the TIA Portal for your fail-safe automation as well.

  • Intuitive operation and the same operating concept as for the generation of standard programs permit a quick entry into the generation of fail-safe programs

  • The same configuration of the F-system as for the standard automation system

  • Ready-to-start: F-runtime group is set up automatically on insertion of the F-CPU

  • Creation of the safety program in the FBD or LAD programming languages

  • Thanks to the integrated library with TÜV-certified function blocks, safety functions can easily be implemented

  • In connection with special signatures for the device parameters, the library concept supports in-house standardization and simplifies the validation of safety-oriented applications

  • The Safety Administration Editor provides central support for the administration, display and modification of safety related parameters

  • Standardized and integrated identification of safety-related resources simplify the overview.

STEP 7 Safety Advanced is the seamless integration of safety into the TIA Portal.
Safety-oriented programs can, however,still be generated using STEP 7 and Distributed Safety. Programs created with STEP 7 Distributed Safety can be migrated into the TIA Portal at any time. Both engineering tools offer commands, operations and blocks for safety-related programs in the LAD and FBD languages.To this end, there is a library with pre-prepared, TÜV acceptedblocks for safety-related functions. You do not need additional engineering expertise, because the programming is done in the traditional STEP 7 environment.


  • Performance increases due to optimized compiler

  • F-OB for
    - Automatic "call" of the F-program "Main Safety„
    - Timing settings and watchdogs

  • No-DIL switch support

  • Simplified setting of F-monitoring time

  • Simplified acceptance printout

  • Functional signature

  • New safety concept for F-applications through flexible
    password and protection level concept

Error detection functions and safety checks when generating the safety program are also supported, as is the comparison of safety programs. Apart from the safety program, a standard program can also be run on the same CPU.
