Safety

SIMATIC Safety Integrated of the integrated F-CPU
For failsafe operation of your plant, program the F-CPUs of the SIMATIC Drive Controller.
Use the "STEP 7 Safety Advanced" of the TIA Portal for this purpose. In combination with
the TIA Portal, the F-CPU offers optimal integration of failsafe systems into your engineering
environment; one controller, one communication system and one engineering platform for
standard and failsafe automation:
● Integration of safety technology
● Instructions approved by German Technical Inspectorate for frequently required safety
applications
● Integration of safety functions up to SIL 3 in accordance with IEC 61508, SILCL 3 in
accordance with IEC 62061 and/or PL e and Category 4 in accordance with ISO 13849-1
● Uniform engineering for standard and safety automation
● Simple documentation of safety-related changes via the F change history in STEP 7
Safety
● Support in the acceptance of the safety program and no renewed acceptance of the
safety program after changes in the standard program
Advantages and customer benefits
Safety Integrated offers the following advantages:
