Broadcast Frames
Broadcast frames deal with information that affects the entire network. When a broadcast frame is
created by a panel or annunciator, it is sent out both network communications ports. Each unit in
turn receives the broadcast in one port, act upon it and pass it on out the other port. Upon reaching
the unit that generated the broadcast frame, that unit then disposes of it. This means that under
normal circumstances, all units receive a broadcast twice and act upon it twice.
If there is break in a communications link (see Figure 2) the broadcast is disposed of by the unit
unable to pass it on. In the situation where a unit has been removed from the loop (see Figure 3),
the broadcast is passed only from com2 to com1 at the jump. In Figure 3, panel 5 passes the
broadcast to panel 3, but panel 3 will not pass the broadcast on to panel 5 since it is supposed to
be communicating to panel 4.
