Event_Enable
WAGO-I/O-SYSTEM 750
BACnet/IP Controller
6.23 Event_Enable
Data Type BACnetEventTransitionBits
Objects Binary Input, Binary Output, Analog Input, Analog Output
Description This property, of type BACnetEventTransitionBits, shall
convey three flags that separately enable and disable report-
ing of TO-OFFNORMAL, TO-FAULT, and TO-NORMAL
events. In the context of Analog Input objects, transitions to
High_Limit and Low_Limit Event_States are considered to
be "offnormal" events.
6.24 Event_State
Data Type BACnetEventState
Objects Binary Input, Binary Output, Analog Input, Analog Output
Description The Event_State property, of type BACnetEventState, is in-
cluded in order to provide a way to determine if this object
has an active event state associated with it. If the object sup-
ports intrinsic reporting, then the Event_State property indi-
cates the event state of the object. If the object does not sup-
port intrinsic reporting, then the value of this property shall
be NORMAL. If the Reliability property is present and does
not have the value NO_FAULT_DETECTED, then the
value of the Event_State property is FAULT. A change in
the Event_State property to the value FAULT is considered
a Fault Event.
6.25 Event_Time_Stamps
Data Type BACnetARRAY[3] of BACnetTimeStamp
Objects Binary Input, Binary Output, Analog Input, Analog Output
Description This optional property, of type BACnetARRAY[3] of
BACnetTimeStamp conveys the times of the last event noti-
fications for TO-OFFNORMAL, TO-FAULT, and TO-
NORMAL events. Time stamps of type Time or Date must
have 'FF' in each octet and Sequence number time stamps
must have the value 0 if no event notification of that type
has been generated since the object was created.
