Directed broadcast
See the one-hop forwarding description in this table.
Distribution mask
A distribution mask or broadcast distribution mask indicates how
broadcast messages are to be distributed on the IP subnetwork
served by the BBMD.
FD
A Foreign Device is a BACnet device that has an IP subnetwork
address different from those comprising the BACnet/IP network
that the device seeks to join. For more information, see section
in chapter
FW_Revision
Firmware_Revision is a property assigned by the vendor to
represent the level of firmware installed in the BACnet device.
MAC address
The MAC address of the router module in the MS/TP network
MAX Info Frames
In MS/TP, the Max_Info_Frames property specifies the maximum
number of information frames the node may send before it must
pass the token to the next node.
MS/TP Master-Slave/Token-Passing
protocol designed specifically for
building automation and control devices as part of the BACnet
standard
One-hop forwarding
There are two ways that a BBMD may distribute broadcast
messages to remote IP subnetworks: One-hop or two-hop
distribution.
For two-hop forwarding, see the description in this table.
For more information on one hop forwarding or directed
broadcast, see section
Broadcast Distribution Table Entry
chapter
. The one-hop mode requires that the IP
router serving the destination subnetwork is configured to
support the passage of directed broadcasts.
Poll For Master frame
In MS/TP, the Poll For Master frame is transmitted by master
nodes during configuration and periodically during normal
network operation. It is used to discover the presence of other
master nodes on the network and to determine a successor node
in the token ring.
Both master and slave nodes shall expect to receive the Poll For
Master frames. The master nodes must respond to Poll For
Master frames, and the slave nodes must ignore them.
Token
MS/TP uses a token to control access to a bus network. A
master node may initiate the transmission of a data frame when
it holds the token. Both master and slave nodes may transmit
data frames in response to requests from master nodes. See
also the description of Max_Info_Frames.
