V One flash/s The Bridge Plus node is offline after just being pow-
ered up, or after hearing a message from another node with the
same network address (duplicate addresses are not allowed). In
this state, the node monitors the network and builds a table of ac-
tive nodes and tokenholding nodes. It remains in this state for
five seconds, then attempts to go to its normal operating state.
V Two flashes, then OFF for 2 s The Bridge Plus node is hearing
the token being passed among other nodes, but is never receiving
the token. Check the network link for an open or short circuit, or
defective termination.
V Three flashes, then OFF for 1.7 s The Bridge Plus node is not
hearing any other nodes. It is periodically claiming the token, but
finding no other node to which to pass it. Check the network link
for an open or short circuit, or defective termination.
V Four flashes, then OFF for 1.4 s The Bridge Plus node has
heard a valid message from another node that is using the same ad-
dress as this node. The node remains offline in this state as long as
it continues to hear the duplicate address. If the duplicate address
is not heard for five seconds, the node then changes to the pattern
of one flash every second.
7.9 Attaching Port Identification Labels
Two sets of Modbus Plus port labels are supplied with your Bridge Plus.
Each set contains two labels. One set is used to identify the Modbus
Plus networks and node addresses at the device’s port connectors.
The other set is a spare.
The labels are designed to provide ready information to persons who
will maintain the network in the future. Enter the Modbus Plus
network numbers and network addresses you have assigned to the
Bridge Plus. Place the labels on the unit so that they can readily
identify the network and node address at each port connector.
Figure 68 shows examples.
