Wireless Communication Faults
Fault
Possible cause
Corrective action
The
WirelessHART
gateway cannot
find a
WirelessHART
device in the
network.
The device has not yet
joined the network.
The joining process may take a while. Check
the join status in the instrument list of the
WirelessHART gateway. Alternatively, check
the wireless communication parameters (join
status) of the device via a HART modem
connected to the device.
The device carries the
wrong network ID and/or
the wrong join key.
Check the wireless communication
parameters of the device via a HART modem
connected to the device. The device and the
WirelessHART gateway must have the same
network ID and join key.
There are not enough
neighboring
WirelessHART devices
within the device's antenna
range.
Check the number of neighbors (Diagnosis >
Wireless Communication). There should be at
least 2 neighbors.
The wireless
connection to a
WirelessHART
device is poor
and disappears
from time to time
There are not enough
neighboring
WirelessHART devices
within the device's antenna
range.
Check the number of neighbors (Diagnosis >
Wireless Communication). There should be at
least 2 neighbors.
Walls or other
static/moving objects block
the radio signals, or the
antenna is not aligned
vertically.
Check the position of the WirelessHART
gateway or use an external antenna. See
chapter 3.1
