The fail-safe SIMATIC S7-1200 Controllers are based on the S7-1200 standard CPUs and offer additional safety-related functions.
They can be used for safety-oriented tasks according to IEC 61508 up to SIL 3 and ISO 13849-1 up to PL e.
Safety-related programs are created in the TIA Portal. The STEP 7 Safety engineering tool offers commands, operations and blocks for safety-related programs in the LAD and FBD languages. To this end, there is a library with pre-configured, TUV-approved blocks for safety-related functions.
Standard controller with integrated safety functions:
Standardized and convenient diagnostic functions for standard and safety
Uniform symbols, data consistency, ...
Modular system with scalable range of CPUs and expandable I/O quantity structure:
One engineering for standard and fail-safe automation
Use of the standard I/O modules together with the fail-safe I/O modules in the central system
Integrated standard PROFINET functionalities for PROFINET controllers and PROFINET iDevice services
Connection of distributed standard I/O via field bus such as PROFINET or PROFIBUS
F-library certified by the German Technical Inspectorate (TUV) for all common safety functions
Free programming of the safety logic using FBD and LAD
Standard-compliant printout of the F-program
One integrated engineering for both standard and safety from S7-1200 to S7-300/400/1500 and WinAC RTX F:
STEP 7 Safety Basic for easy engineering of the CPU 1200 FC
STEP 7 Safety Advanced for the entire fail-safe SIMATIC S7 portfolio
Integrated system diagnosis of the CPUs, for standard and safety:
Consistent plain text display of system diagnostic information in the TIA Portal, HMI and web server
Messages are updated even if the CPU is in STOP state
System diagnostics integrated in the CPU firmware. Configuration by user not required
The diagnostics is automatically updated on configuration changes.
2 fail-safe compact controllers with graded performances in the versions DC/DC/DC and DC/DC/relay
