    Hi,

    The safety program put your cpu to STOP.

    The data used to calculate your outputs in the safety program changed between start and end of your safety program (OB123).

    Please check this siemens guide:

    https://support.industry.siemens.com/cs/document/22099875/simatic-industrial-software-s7-distributed-safety-configuring-and-programming?dti=0&lc=en-WW

    In your error log I can see that the issue is with your %Q430.0 output.

    Please check the network where your %Q430.0 output is writen. maybe the data (inputs and other data) used to calculate this output are changed in other tasks.

     

    Best regards
