Safety Applications with S7-1200 FC CPU
https://support.industry.siemens.com/cs/document/109478932/safety-applications-with-s7-1200-fc-cpu
The document contains a complet of 30 scenarios for safety door and emergency stop applications. An F-block for the direct use of an S7-1200 FC CPU is available to you for each scenario. In addition to the easy use of the S7-1200 FC CPU, the document also explains what has to be considered to achieve a specific PL/SIL.
Risk analysis and assessment are generally followed by questions regarding implementation – to achieve the required PL according to ISO 13849 or SIL according to IEC 62061 (wiring, engineering, etc.).

This is the starting point of this application example. Using a modular structure, it shows the basic procedure for implementing a safety-related application.

The application example separately examines safety door (with and without guard locking), emergency stop and various combinations.

For all the applications shown in this application example, we have prepared solutions for PL c/SIL 1, PL d/SIL 2 and PL e/SIL 3. Each individual application is implemented within a safety-related function block.

We have prepared a exhaustiv of 30 applications for you. All 30 F-blocks are clearly stored in a block library. This allows you to integrate an F-block into your custom STEP 7 project (TIA Portal) and customize it to your requirements. Or you can directly download the hardware configuration that is provided as well.

The S7-1200 FC CPU is the excelent controller to implement simple stand-alone solutions.
