4320 Wireless Position Monitor
SEARCHING—the device is waiting to detect the
presence of a wireless network with the same
Network ID and join key.
NEGOTIATING—the presence of a wireless network
with the same network parameters has been
detected and the device is attempting to join the
network.
CONNECTED—the device has detected the
presence of a wireless network with the same
network parameters and has successfully joined the
network.
OPERATIONAL—the device is operating within a
wireless network.
DISCONNECTED—the device has become
disconnected from the wireless network.
IDLE—the device has been instructed by a HART
command not to attempt to participate in a wireless
network.
DISCONNECTED and IDLE are used in
maintenance activities.
Network ID—displays the default Network ID.
Join Key to Network—enter the Network ID (up to
5−digits) and the Join Key (4 sets of 8 hexadecimal
digits). The Join Key is used for encrypting the data
on the wireless network. The Network ID and the
Join Key must be the same for all devices connected
to a gateway.
The Network ID is shipped with a
default value of 1229 and the Join Key
with a default value of all zeros. These
must be changed prior to use.
D Burst Mode
Burst Mode—enabling burst mode provides
continuous communication from the wireless position
monitor. Burst mode applies only to the transmission
of burst mode data and does not affect the way other
data is accessed.
Access to information in the instrument is normally
obtained through a wireless network or a Field
Communicator. The Field Communicator or the
network may request any of the information that is
16
Note
normally available, even while the instrument is in
burst mode. Between each burst mode transmission
sent by the instrument, a short pause allows the
Field Communicator or control system to initiate a
request. The instrument receives the request,
processes the response message, and then
continues "bursting" the burst mode data.
Update Period—indicates the set Burst Period.
Change Update Pe...—change Update Period allows
you to change the burst period. The maximum burst
period is 1 hour.
Show Burst Variables—there are six burst
commands; Command 1, Command 2, Command 3,
Command 9, Command 48 and Command 178.
D Command 1 returns the Primary Variable
(PV) for the 4320
D
Command 3 returns the loop current,
Percent of Range, Close Trigger Status, Open
Trigger Status, and Temperature (outside of the
instrument).
D
Command 48 returns status about the
instruments operation.
Commands 2 and 9 are not covered in
this manual. Command 178 is used
exclusively with the 1420 gateway for
efficiency.
D Broadcast Power
Power Level—set the power level to the desired
setting, either High (10 mW) or Low (2 mW).
D Power Information
Power Source—indicates the power source being
used. The 4320 operates solely of its (internal)
power module.
Power Module Type—choose the type of power
module being used; either Standard or Extended
Life.
Power Module Date—indicates the date the power
module was installed.
Power Module Volt—indicates the voltage of the
power module.
