Disclosed is an automation system ( 1 ) for executing safety-relevant automation functions. Said automation system ( 1 ) comprises one or several control componentries ( 10 ) and one or several input/output componentries ( 30, 30',50 ) that are connected thereto. The control componentry ( 10 ) is provided with standard program parts ( 11, 12 ) and fail-safe program parts ( 13, 14 ) to communicate with the connected input/output componentries ( 30, 30',50 ) via corresponding standard bus protocols (S) and fail-safe bus protocols (F). At least one of the input-output componentries ( 30 ) is controlled by both the standard program parts ( 11, 12 ) via the communicated standard bus protocol (S) and the fail-safe program parts ( 13, 14 ) via the communicated fail-safe bus protocol (F), said fail-safe bus protocol (F) having greater priority for said input/output componentry ( 30 ) than the standard bus protocol (S).
