BACnet COV Throttling

 

 

Enable COV Throttling

 

Under normal circumstances, COV Throttling should be enabled to prevent 
excessive network traffic if an object's COV Increment is set too low. See 
EXCEPTION below. 

When enabled, if an object generates excessive COV broadcasts (5 updates in 3 
seconds), the module driver automatically throttles the broadcasts to 1 per 
second. Also, if the object's value updates excessively for 30 seconds, an alarm 
is sent to the i-Vu® application listing all objects that are updating excessively. A 
Return-to-normal alarm is sent only after all objects have stopped updating 
excessively. 

EXCEPTION

  In rare circumstances, such as process control, a subscribing object 

may require COV updates more frequently than once per second. For these 
situations, clear this checkbox, but make sure that your network can support the 
increased traffic. You also need to disable the 

Excessive COV

 alarms under the

BACnet device object properties for the i-Vu® Open Router 

 

i-Vu® Open Router communication 

 

Configuration

 

NOTE  

The three APDU fields refer to all networks over which the i-Vu® Open 

Router communicates. 

Max Masters and Max Info 
Frames

 

Max Masters

 - defines the highest MS/TP Master MAC address on the MS/TP 

network.  

For example, if there are 3 master nodes on an MS/TP network, and their MAC 
addresses are 1, 8, and 16, then Max Masters would be set to 16 (since this is 
the highest MS/TP MAC address on the network).  

This property optimizes MS/TP network communications by preventing token 

passes and “poll for master” requests to non

-existent Master nodes.  

In the above example, MAC address 16 knows to pass the token back to MAC 
address 1, instead of counting up to MAC address 127. Each MS/TP master 
node on the network must have their Max Masters set to this same value. The 
default is 127. 

Max Info Frames 

- defines the maximum number of responses that will be sent 

when the i-Vu® Open Router receives the token. The default is 10 and should be 
ideal for the majority of applications. In cases where the i-Vu® Open Router is 
the target of many requests, this number could be increased as high as 100 or 
200.
