*1 When a value is written to the PresentValue property of a MultiStateOutput object, the value is temporarily stored to the PriorityArray
property whose index number is indicated by the Priority. The value stored to the PriorityArray property, whose index number is the
smallest, is used for the PresentValue property.
Until the value of the PriorityArray property, whose index number is used for the PresentValue property, is returned to Null, the value of
the PriorityArray property of the index number is used for the PresentValue property.
Precautions
• The STATUS in the internal memory of a BACnet module cannot be changed from a program.
• Do not change the value of a PVWritten in a program, since the PVWritten cannot be used as a flag.
A value is written to the PresentValue property regardless of the value of the PVWritten in the program (in the buffer
memory) since a BACnet module operates based on the information in the internal memory.
