Communication time-out parameters define the minimum delay between UDPpackages received from the master. The timer is reset and started after each received UDP pack-age. This parameter can be used if the master is periodically polling the slaves.P5.9.3.1.3 P ROTOCOL IN USEBACnet/IP protocol can be enabled and disabled with this parameter. When the parameter value isset to "1" the BACnet/IP protocol is enabled and disabled when set to "0".P5.9.3.1.4 BBMD IPThe IP address of BACnet/IP Broadcast Management Device.P5.9.3.1.5 BBMD P ORTThe port number of BACnet/IP Broadcast Management Device.P5.9.3.1.6 BBMD TIME TO L IVEThis parameter specifies the length of time during which the BBMD forwards broadcast messages.NOTE! The BBMD (BACnet/IP Broadcast Management Device) allows you to use BACnet IP acrossa large network. In the standard IP technology, routers don't forward broadcast messages. To solvethis problem, the BBMD provides a re-broadcast on the local domain for all the messages that wereoriginally broadcast on another domain. It is not necessary for all the BACnet IP devices to supportBBMD. It is enough for one device on the IP domain to function as the BBMD. This device must beconfigured to interact with BBMD's on other domains to provide the broadcast support.
