Wireless Communication Faults

Fault
PACTware
cannot find the
device when
communicating
via
WirelessHART
gateway WHA-
GW.
The device
does not join
the network.
Device
disappears
sporadically
from the
network
Possible cause
The device has not yet joined the
network.
The device carries the wrong
network ID and/or the wrong join
key.
No battery or low battery
The device carries the wrong
network ID and/or the wrong join
key.
No neighboring WirelessHART
devices are within the device's
antenna range.
Device not mounted correctly
Device not trying to join
There are not enough neighboring
WirelessHART devices within the
device's antenna range.
Corrective action
The joining process may take a
while. Check the join status in the
gateway's Instrument List.
Alternatively, check the wireless
communication parameters (join
status) of the device via a HART
modem connected to the device. If
the device does not join, check
the next fault.
Check the wireless
communication parameters of the
device via a HART modem
connected to the device. The
device and the gateway must
have the same network ID and
join key.
Check that a fresh battery of the
correct type is inserted.
Check the wireless
communication parameters of the
device via a HART modem
connected to the device. The
device and the gateway must
have the same network ID and
join key.
• Check the number of neighbors
in the device DTM (wireless
communication parameters).
There should be at least 2
neighbors.
• If there are no reachable
neighbors, check the device's
mounting position: Are there any
obstacles? If yes, change the
mounting position.
• If there are no reachable
neighbors and you can not
change the device's mounting
position: Try moving an other
WirelessHART device in the
network, or adding a new one.
Check that the adapter has been
mounted correctly (see chapter
3.1).
Check whether the device is trying
to join the network (LEDs): if not,
start a new connection attempt by
pressing the correct button (see
chapter 1.0.9).
Check the number of neighbors in
the device DTM (wireless
communication parameters).
There should be at least 2
neighbors.
