6.3.3.2 SAPI of SafetyProvider

where it can be used to trigger a return from fail-safe substitute values ( FSV ) to actual process values ( PV ), see B.3.4 . OperatorAckRequested Boolean O Indicates that an operator acknowledge ... SafetyConsumer is instructed (via Bit 1 in ResponseSPDU.Flags , see 6.2.3.2 ) to deliver FSV instead of PV to the safety application program. NOTE If the replacement of process values by FSV
