With Safety Integrated, Siemens provides a comprehensive portfolio of control, drive, and switching technology that is unique anywhere in the world, and meets all of the requirements for functional safety of machines and plant. Safety Integrated represents the rigorous implementation of safety technology as defined by Totally Integrated Automation. It succeeds partly through the direct integration of safety functions into our standard products, and also through the consistent and convenient incorporation of safety technology into standard automation systems. One controller, one communication system, and one engineering environment for standard and fail-safe automation. The result is all-round efficient and reliable protection for humans, machines, and the environment. Using the SIMATIC STEP 7 Safety Advanced engineering tool, users can create their programs for both standard and fail-safe tasks using exactly the same engineering and control concept, for example.
