Programming
HART enables you to reset the analyzer to factory-default
values using the “GLI SETUP” menu of the master. The
execution of this command may take a relatively long time
to complete. Consequently, the analyzer cannot respond to
other commands until reset is complete.
1.
With the “GLI SETUP” top-level menu screen dis-
played, select “MASTER RESET” line and press
key
.
2.
After the “MASTER RESET” submenu screen appears,
select the “Yes” line.
3.
Press the
F4 key
to execute master reset and to return
to the “GLI SETUP” top-level menu screen.
The “REFRESH” function enables you to initiate HART to re-
synchronize the master to the analyzer in case changes made
at the analyzer are not reflected by the hand-held terminal.
NOTE:
Since HART only performs housekeeping tasks
upon initialization, the “REFRESH” function need
only be performed once. However, it may be used
anytime thereafter to refresh the variables in the
master.
1.
With the “MAIN MENU” top-level menu screen dis-
played, select the “REFRESH” line and press
key
.
2.
A “Please wait...” message will be displayed until the
master has finished retrieving variables from the ana-
lyzer. Thereafter, the display will be returned to the
“MAIN MENU” top-level screen.
The Universal Commands and some Common Practice
commands inherent in the HART protocol can be used for
limited operability. The Device Specific Command set for all
existing GLI analyzers is available on request for creating a
full-featured HART-capable program to run on an IBM-
compatible PC.
