Why can't I access a node present in the network?
If you are having difficulty accessing a node present in the network (i.e. it can't be
acquired using the search function, and its associated NVs can't be read), you
should consider the following possible causes:
Possible Cause Number One
The physical connection between the node which you are attempting to access and
your XILON is faulty.
Explanation/Action
Check the cable connecting your XILON with the L
ON
W
ORKS
network. If this
problem applies to only an individual node (i.e. if other nodes are unaffected and
can be accessed without a problem), then the affected node's physical connection
to the network is probably faulty, or the node has been turned OFF. Check that the
node has been turned ON and that its connection to the L
ON
W
ORKS
network is
intact.
Possible Cause Number Two
The node which you are attempting to access and your XILON are equipped with
different, incompatible transceivers.
Explanation/Action
If your XILON and the node which you are attempting to access are equipped with
different, incompatible transceivers, it will probably be impossible for them to
exchange information with each other. Both your XILON and all Honeywell nodes
have transceivers of the type TP/FTT-10A; you can thus encounter this problem
when attempting to access non-Honeywell nodes. To access such a node, you will
have to either insert a suitable router (see "Inserting a Suitable Router" below) or
reconnect your XILON to the network at another location with a compatible
communication channel (see "Reconnecting at a Different Location" below).
Inserting a Suitable Router
A router is equipped with two transceivers of different types, thus enabling it to
transmit network communications between different communication channels. If
you wish to solve this problem by inserting a router, one of its transceivers must
correspond in type to your XILON's (i.e. TP/FTT-10A), while the other transceiver
must correspond to that of the node which you are attempting to access. This
router should be configured as either a repeater or as a bridge.
Reconnecting at a Different Location
Especially in large networks, routers are usually already present as part of the
network infrastructure. It may therefore be possible for you to make use of such a
pre-existent router by reconnecting your XILON to the L
ON
W
ORKS
network at a
different location.
Possible Cause Number Three
Your XILON is not a member of the zero domain.
Explanation/Action
In order to be able to receive a service pin message, one of the two domains to
which your XILON is assigned must be the zero-length domain. To remedy this
situation, use the
<F10>
hot key to go to "set-up addressing" and assign your
XILON to the zero-length domain by entering a "0".
Possible Cause Number Four
The node which you are attempting to access and your XILON have a different
domain setting.
