EC: Simatic Step 7 Safety Advanced v11.0

Safety - Machine safety: Siemens Simatic Step 7 Safety Advanced V11 option as part of its TIA Portal, providing end users with configuration and programming tools required for generating a fail-safe program within Siemens TIA Portal. This is a Control Engineering 2013 Engineers' Choice Awards Honorable Mention.

The introduction of the Siemens Safety Advanced program within TIA Portal strengthens the ability to support end users with safety functions that can easily be integrated into standard automation processes, as well as offering a value-added service as part of Safety Integrated portfolio of Simatic products. TIA Portal framework enables all Siemens Programmable Controllers, HMI operator panels, and drives to be configured in the same development environment. As with the entire TIA Portal platform, this new Safety Advanced feature allows for intuitive operation and quick entry into the generation of fail-safe programs, and due to the integrated library with TUV-certified function blocks, safety functions can easily be implemented. Also, the library concept supports in-house standardization and simplifies the validation of safety-oriented applications.

The Safety Advanced feature has the same configuration of the fail-safe systems as for the standard automation system, and with the "Ready-to-Start" function, the fail-safe runtime group is set-up automatically on insertion of the fail-safe controller. Siemens increased the ease-of-use for the Safety Advanced function by creating the program in the FBD (Function Block Diagram) or LAD (Ladder) programming languages. However, fail-safe programs can still be generated using Step 7 and Distributed Safety, migrating these into the TIA Portal at any time. The program’s Safety Administration Editor provides central support for the administration, display and modification of safety-related parameters, while the identification of safety-related resources are standardized for simplicity. With the Safety Advanced feature, error detection functions and safety checks when generating the safety program are also supported, as is the comparison of safety program. A standard program can also be run on the same CPU.
