The fail-safe SIPLUS 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 STEPВ 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, TГњV-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 (TГњV) 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:
  • STEPВ 7 Safety Basic for easy engineering of the CPU 1200 FC
  • STEPВ 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
