Device Address
Setting a device address is not necessary for local operation, but must be set if
configuring the SITRANS LUT400 for use on a HART network. See
Device Address 4.1.

page 217.
Testing the configuration
After programming the device, it is recommended that you test the device to ensure that it
performs to your specifications. This test can be run in simulation mode or by varying the
actual level in the application. The latter is preferred as it more accurately represents
running conditions. However, if it is not possible to do a physical test, a simulation will
ensure that control programming is correct. For further details, see
Simulation
on page
120, and
Application test
on page 123.
