12 EXAMPLE OF OPERATION
Program example
• When the safety refresh communication status is normal, digital operation values are obtained from CH1 to CH4 of the
R60AD8-G and output to Digital obtained value (SA\D1030 to SA\D1033).
• To skip the start-up diagnostics, turn on Start-up diagnostics skip request (SA\M1002).
• When Execution status (SA\M1003) and Normal completion (SA\M1004) of the SIL2 safety program FB are on, processing
runs according to Status code (SA\D1050 to SA\D1053) of each channel. For channels whose Status code is Double input
discrepancy detection function completed (8004H), processing for normal state runs. For channels whose Status code
indicates an error (C001H or larger), Channel error (SA\M1011 to SA\M1014) turns on.
• Execution status (SA\M1003) and Error completion (SA\M1005) of the SIL2 safety program FB are on, System error
(SA\M1010) turns on.
• To clear the errors currently occurring, turn on Module error clear (SA\M1001). Turn off Module error clear (SA\M1001) after
checking the error reset.
