OUTPUT_REF

The data type OUTPUT_REF contains data describing the state of a digital output. In addition to the switching state it contains time stamps for state changes.

TYPE OUTPUT_REF :

Name	Type	Description
Level	BOOL	Current switching state of the digital output
NextStateChangeValid	BOOL	NextStateChangeValid is TRUE, if the time stamp NextStateChange is valid.
NextStateChange	T_DCTIME32	Time of the next change of state (distributed clock TimeStamp)
NextOnTimeValid	BOOL	NextOnTimeValid is TRUE, if the time stamp NextOnTime is valid.
NextOnTime	T_DCTIME32	Time of the next positive switching edge (distributed clock TimeStamp)
NextOffTimeValid	BOOL	NextOffTimeValid is TRUE, if the time stamp NextOffTime is valid.
NextOffTime	T_DCTIME32	Time of the next negative switching edge (distributed clock TimeStamp)
