Echelon i.LON 100 e2 Internet Server - Manual (Page 164)

i. LON 100 Internet Server Programmer’s Reference
Property Description
<DateTimeVal> The update events for each date-based schedule are signified by a list
of <DateTimeVal> elements. Each update event will be used on the
days that this date-based schedule is active.
For each <DateTimeVal> element, you must enter a value, or select a
value definition defined for the data points the Event Scheduler is
updating, as the <UCPTscheduleValue> property. You can define
value definitions for each data point with the DataServerSet function.
For more information, see DataServerSet on page 5-10.
You will also enter the local time (UCPTscheduleTime), which defines
the time of day when the data points selected for your Event Scheduler
will be updated to the value specified for the <UCPTscheduleValue>
property. This time must be entered in 24-hour format, e.g. 16:30
represents 4:30 PM.
NOTE: The Event Scheduler application supports a maximum of 1024
update events per
i. LON 100. As a result, the total number of
<DayTimeVal> and <DateTimeVal> elements defined in the i. LON
100 cannot exceed 1024.
Now, consider the <DateBased> element in the sample <Data> parameter at the beginning
of this section. That date-based schedule section is effective on the dates assigned to the
Holiday and Christmas calendar exceptions. At 3:40 AM on every date these exceptions apply
to, the data points affected by this function are updated to their BYPASS values. At 11:00
PM on every date these exceptions apply to, the data points affected by this function are
updated to their OFF values. This assumes that the priority level assigned to the data point
being updated is between 112 and 255.
