    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).

    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

  2. Hello, Try to use ACK_GL instruction in your safety program. This block re-integrates all passivated I/O modules. If after acknowledgement the problem still exist, please check the wiring of the two channels. Try also to increase the descrepancy time. Good luck.
