4.2.1.2.4.3 Scheduling (SCHED)
Actions that are to be managed with regard to time can be set through Sched-
uling. Two basic scheduling processes can be set.
• Weekly schedules
• Special schedules for exception days
Whether a schedule is used and which type is supported can be selected ac-
cording to need.
Example: SCHED-A
4.2.1.2.4.4 Trending (T)
Time/value pairs are transmitted. Sampling takes place parameterized at nar-
row intervals so that exact data for immediate testing is delivered. The data are
therefore not intended for long-term storage.
The recording of trends can take place through the COV service "Transmit
with change in value" or by periodic query.
Notifications are issued through intrinsic or rule-based reporting.
Example: T-VMT-A Trending-Viewing and Modifying Trends-A

BACnet/IP Controller
The Client (A) processes alarms and notifications. The
services ConfirmedEventNotification and UnconfirmedE-
ventNotification are necessary for this. These services
enable a report back to the initiator regarding the proc-
essability of the event notification.
Scheduling-A
Device A changes schedule/calendar in Device B.
Device A must support DS-RP-A and DS-WP-A,
therefore read Device B and be allowed to write.
Device A displays the trending records of Device B and
alters the Trend-Log Parameter there.
