6.2.3.1 InFlagsType

The InFlagsType a subtype of the Byte DataType with the OptionSetValues Property defined. The InFlagsType is formally defined in Table 14.

CommunicationError can be used as a trigger, e.g. for a communication analysis tool. It is not forwarded to the safety application by the SafetyProvider. If CommunicationError is necessary in the safety application, bidirectional communication can be implemented and the value of CommunicationError can be put into the user data.

0: No error

1: An error was detected in the previous ResponseSPDU.

OperatorAckRequested1Used to inform the SafetyProvider that operator acknowledgment is requested.
FSV_Activated2Used for conformance test of SafetyConsumer.SAPI.FSV_Activated.

Bits 3 to 7 are reserved for future use and shall be set to zero by the SafetyConsumer. They shall not be evaluated by the SafetyProvider.

The InFlagsType representation in the AddressSpace is defined in Table 15.
