Defining ShortAddress
The defined short address is needed for identification of the field device during
the localization phase.
1.
To enter a short address between 0 ... 15, press the or buttons.
2.
Confirm your entry with
OK.
Selecting LocateMethod
According to the HART standard, more than one HART field device can be present in a
HART circuit. But the device can communicate only with a single HART field device.
This HART field device is identified during the localization phase.
1.
Select the localization method with the or buttons.
2.
Select
fixed.
The device communicates with the field device that has a short address
defined under
ShortAddress.
3.
Choose
search.
During booting, the device searches for the field device with the smallest short
address, beginning with the short address defined under
ShortAdress. The address
of the field device found is stored by the device under
ShortAddress. This
accelerates the device starting when it boots again.
4.
Confirm your entry with
OK.
Note!
Note that the field device can be put into burst mode, in accordance to the isolated
barrier configuration. This also applies when a different HART master is in the HART
circuit. If a different HART master changes the burst configuration of the field device, the
isolated barrier waits until the other HART master logs out of the HART circuit. The
isolated barrier assumes that the other HART master is logged off when it does not
send a message for approximately 60 s. After this period of time, the isolated barrier
activates the burst configuration of the field device.
