9.3.3

Using the Read Function on a Scheduler

You can use the Read function to retrieve the events scheduled in any Scheduler that you have added

to the SmartServer. You can filter events using an xSelect statement and specifying one or more

Scheduler items. You can use the following filters in an xSelect statement when using the Read

function on a Scheduler:

UCPTlastUpdate

When an event occurs. You can compare the specified start and stop

times using equal, less (or equal), great (or equal). UCPTstop is set

to time of last shown event. You need to check whether UCPTstop

differs from UCPTlastUpdate to make the next request start from the

UCPTstop time.

UCPTeventFilter This property may have one of following values:

• EF_NUL: Show all events. This is the same as not specifying

and UCPTeventFilter.

• EF_DAY: Show only first event scheduled for each day.

• EF_SCHEDULE: Show only one event for each scheduler.

position() Position of the event in previously selected list. You can use this

filter to limit the number of events in a result. You can compare the

number of events to be returned using equal, less (or equal), or great

(or equal). You can request a maximum of 2,500 events; however,

more than 2,500 events may be returned.

Note: The last instance of an event before the specified start date is

always returned (if it exists), and it is not counted by the position()

constraint.

You can include one item of type UFPTscheduler_Calendar_Request_Data, which causes a Read

function on a Calendar item. This information is used to calculate date-based events. You can also

include an item of type UFPTscheduler_RealTimeClock_Request_Data, which defines start point for

relative times for each day. By default, all relative times are calculated from 0:00:00. If calendar

and/or real time clock data is specified, the data in the response is bound to given start and stop dates.
