Action(s)
Check the Diagnosis function of the
DTM to find out what kind of error
has occurred. See chapter 6.4
Check wiring.
Corrective Action(s)
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.
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 device 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 6
Check the number of neighbors in the device
DTM (wireless communication parameters).
There should be at least 2 neighbors.
