Appendix A.5.3.

 

Using Intrinsic Reporting for a Multistate Value  

To  use  Intrinsic  Reporting  for  a  Multistate  value,  it  is  necessary  to  classify  each  of  the  states  as  either  Normal, 
Alarm or Trouble.  This is done by adding another column to the Offset_Table, called Table_User_Value.  Each state 
is then classified by inserting one of the following values in its row: 

0 = normal 
1 = alarm 
2 = fault 
 

//set up a look up table

Note

: The state value (Table_Index_Value) is an enumerated value greater than zero.  Zero is not a valid value, but 

since many client side configurations will wake up with values of zero, the BACnet Server will treat a value of zero 
as a normal value (i.e. not as an alarm or fault value) 

Appendix A.6.

 

COV and Intrinsic Reporting 

The  COV  (Change  of  Value)  and  Intrinsic  Reporting  services  are  two  distinct  ways  in  which  point  values  can  be 
reported  to  a  client  workstation  as  they  change,  i.e.  in  an  event-driven  opposed  to  a  polling  method.    This  can 
increase performance dramatically compared to polling method alone.  It also reduces network traffic significantly. 

For BACnet/MSTP, only MSTP Master Nodes support COV and Intrinsic Reporting  

The services are suited to different purposes: 

 

COV  is  suited  to  value  updates.    On  analog  points  the  sensitivity  can  be  set  using  the  COV_Increment 
property.  Only changes larger than the COV_Increment value will be reported. 

 

Intrinsic  Reporting  is  used  for  alarming.    It  is  implemented  via  Notification_Class  objects,  which  can 
receive  subscriptions  from  client  workstations  that  add  themselves  to  the  RecipientList  property  of  a 
Notification_Class 

object. 

 

Notifications 

are 

done 

using 

ConfirmedEventNotification 

or 

UnconfirmedEventNotification. Intrinsic Reporting also allows  for alarms to be acknowledged (using the 
AcknowledgeAlarm  service)  and  for  all  subscribed  client  workstations  to  be  notified  of  alarm 
acknowledgements (using EventNotifications of type ACK_NOTIFICATION)..
