		InputDataCallbackSwallowsException
	)

Test:

OnInput swallows application callback exceptions.

TEST_F() [5/93]

profinet::cyclic::TEST_F	(	CyclicCallbackTests	,
		InputStatusCallbackRunsOnBadTransition
	)

Test:

OnInputStatus runs when the device changes the IOPS value to BAD.

Definition at line 878 of file test_cyclicMore.cpp.

References controller, profinet::rt::IOXS_BAD, and profinet::rt::IOXS_GOOD.

TEST_F() [6/93]

profinet::cyclic::TEST_F	(	CyclicCallbackTests	,
		InputStatusCallbackRunsOnGoodTransition
	)

Test:

OnInputStatus runs when the status changes from unknown to GOOD.

TEST_F() [7/93]

profinet::cyclic::TEST_F	(	CyclicCallbackTests	,

Test:

OnTimeout and OnError registrations are accepted without invoking them.

TEST_F() [10/93]

profinet::cyclic::TEST_F	(	CyclicControllerConformanceTest	,
		NonZeroTransferStatusIsRejected
	)

Test:

Verify that a non-zero TransferStatus frame is rejected.

TransferStatus must be validated independently of DataStatus. A cyclic frame with a non-zero TransferStatus must not be delivered as valid input.

Definition at line 223 of file test_cyclicControllerConformance.cpp.

References controller, and Running.

TEST_F() [11/93]

profinet::cyclic::TEST_F	(	CyclicControllerConformanceTest	,
		TxContinuesWhileControllerIsInFault
	)

Test:

Verify that cyclic output transmission continues while in FAULT.

The controller must continue transmitting cyclic output frames while in FAULT. Stopping transmission would allow the device Data Hold Timer to expire and may terminate the Application Relationship.

IOCS is already reported as BAD in FAULT, so continuing transmission does not imply that the output data is valid.
