Feedback_Value
WAGO-I/O-SYSTEM 750
BACnet/IP Controller
plies to a given day, the relative priority of the SpecialEv-
ents shall be determined by their EventPriority values. If
multiple overlapping SpecialEvents have the same Event-
Priority value, then the SpecialEvent with the lowest index
number in the array shall have higher relative priority. The
highest EventPriority is 1 and the lowest is 16. The Event-
Priority is not related to the Priority_For_Writing property
of the Schedule Object.
If a BACnet Device supports writing to the Excep-
tion_Schedule property, all possible choices in the
BACnetSpecialEvents shall be supported. If the size of this
array is increased by writing to array index zero, each new
array element shall contain an empty List of BACnetTime-
Value.
If the Exception_Schedule property is written with a sched-
ule item containing a data type not supported by this in-
stance of the Schedule object (e.g., the
List_Of_Object_Property_References property cannot be
configured to reference a property of the unsupported data
type), the device may return a Result(-) response, specifying
an 'Error Class' of PROPERTY and an 'Error Code' of
DATATYPE_NOT_SUPPORTED.
