Property Description
<UCPTpriority> The priority assigned to the schedule, from 0 (highest priority) to 255
(lowest priority). The priority chosen here must be greater than or
equal to the current priority level assigned to a data point when the
Event Scheduler attempts to update that data point. If it is not, the
data point will not be updated successfully.
For a more detailed description of data point priority levels, see Data
Point Values and Priority Levels on page 3-5.
<UCPTweekdays> The days of the week this day-based schedule will be active, as a
comma-separated list of Boolean values (1=effective, 0=not effective),
starting with Saturday. For example, to create a day-based schedule
that is effective on Monday and Tuesday, enter:
0,0,1,1,0,0,0
Or, to create a schedule that is effective Sunday and Wednesday,
enter:
0,1,0,0,1,0,0
The default value for this property is 0,0,0,0,0,0,0.
<DayTimeVal> The update events for each day-based schedule are signified by a list of
<DayTimeVal> elements. Each update event will be used on the days
that this day-based schedule is active.
For each <DayTimeVal> 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. 15:30
represents 3:30 PM.
NOTE: The EventScheduler 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 <DayBased> element in the sample <Data> parameter at the beginning of
this section. That day-based schedule section is effective on Saturday and Sunday of the date
range specified by the <UCPTscheduleEffectivePeriod> property. At 3:40 AM on every
Saturday and Sunday, it updates all data points selected for the Event Scheduler to their ON
value. At 6:40 PM, it updates these data points to their OFF value. This assumes that the
priority level assigned to the data point being updated is between 240 and 255.
