Timed Event Handling 29
Timed Event object, using the property type:
"PROP_BEGIN_TIME_OFFSET_MINUTES". This is an integer data-type with a
value between -1439 and 1439.
• If a Duration Time Type:
• Perform a BACnet "Write Property" command on Instance Zero of the Timed
Event object, using the property type: "PROP_BEGIN_TIME_DURATION". This
is an integer data-type with a value between 0 and 2,147,483,647 (minutes).
Step 5: Write the Timed Event "End Time". If no event duration is required, set this equal
to the "Start Time".
a: First - Perform a BACnet "Write Property" command on Instance Zero of the
Timed Event object, using the property type: "PROP_END_TIME_TYPE". This
property is an integer data-type with an enumeration value: 0 = Real, 1 =
Astronomical, 2 = Duration.
b: Select one of the following actions, depending upon the value of this property:
• If a Real Time Type:
• Perform a BACnet "Write Property" command on Instance Zero of the Timed
Event object, using the property type: "PROP_END_TIME_HOUR". This is an
integer data-type with a value between 0 and 23.
• Then, perform a BACnet "Write Property" command on Instance Zero of the
Timed Event object, using the property type: "PROP_END_TIME_MINUTE".
This is an integer data-type with a value between 0 and 59.
• If an Astronomical Time Type:
• Perform a BACnet "Write Property" command on Instance Zero of the Timed
Event object, using the property type: "PROP_END_TIME_ASTRO". This is an
integer data-type with an enumeration value: 0 = Sunrise, 1 = Sunset.
• Then, perform a BACnet "Write Property" command on Instance Zero of the
Timed Event object, using the property type:
"PROP_END_TIME_OFFSET_MINUTES". This is an integer data-type with a
value between -1439 and 1439.
• If a DURATION Time Type:
• Perform a BACnet "Write Property" command on Instance Zero of the Timed
Event object, using the property type: "PROP_END_TIME_DURATION". This is
an integer data-type with a value between 0 and 2,147,483,647 (minutes).
Step 6: Write the Timed Event "Recurrence".
a: Perform a BACnet "Write Property" command on Instance Zero of the Timed
Event object, using the property type: "PROP_RECURRENCE_TYPE". This
property is an integer data-type with an enumeration value: 0 = Once, 1 =
Hourly, 2 = Daily, 3 = Weekly, 4 = Monthly, 5 = Yearly, 6 = Custom, 7 = Holiday.
b: Select one of the following actions, depending upon the value of this property:
• If a Once Recurrence type:
• Perform a BACnet "Write Property" command on Instance Zero of the Timed
Event object, using the property type:
"PROP_RECURRENCE_ONCE_MONTH". This is an integer data-type with a
value between 1 and 12.
• Then, perform a BACnet "Write Property" command on Instance Zero of the
Timed Event object, using the property type:
"PROP_RECURRENCE_ONCE_DAY". This is an integer data-type with a value
between 1 and 31.
• Finally, perform a BACnet "Write Property" command on Instance Zero of the
Timed Event object, using the property type:
"PROP_RECURRENCE_ONCE_YEAR". This is an integer data-type with a
value between 10 and 99 (an offset from the year 2000).
• If a Weekly Recurrence type:
• Perform a BACnet "Write Property" command on Instance Zero of the Timed
Event object, using the property type: "PROP_RECURRENCE_WEEKLY". This
is a character string data-type with a value that represents each day as either '1'
or '0', on or off. As an example, the weekly string "1000010" would represent the
