Hi Christian,
Use with activated fail-safe on the PLC is possible with the TIAX Library Workflow in TIA Portal. However, the library types from the TIAX Library Workflow can only be used for the non-safety program code part. It is only applicable to standard code on the failsafe PLC. In addition, I highly recommend implementing the coupling between non-safety and safety code using the approach described on the TIA page in the Safety Programming Guide. The Guide find here
If you want to debug your in AX created code with TIAX Library Workflow, you can debug this with the sdb (SIMATIC AX Debugger). This is the reason, why the sdb is currently the only component that can deal with the activated failsafe on the PLC.
Here is a brief overview
What would full safety support in AX look like for you? For which workflow should safety be supported (TIAX Direct Loading or AX Standalone)?
Happy coding
Kevin
Thank you for you feedback. Do you think in a transition phase more on TIAX Library Workflow with Safety or TIAX Direct loading Workflow with Safety?
You asked, is there there any plans to support fail-safe code implementation in AX Standalone. Yes, it is. We plan a first release in end of 2026
😊🚀
Happy coding
Kevin
