10.6 LCD structure

The Device TAG and Node Address are always visible in the
top side of the LCD. The line/s and bar-graph view depends by
the HMI_MODE Selection
The displayed variables are identified by a max of the three
character strings visible on the left side of the value when two
lines mode is selected or below the value when one line mode
is selected. The list of all the strings identifying the variable is
available in the HMI_VARIABLE_1 within the HMITB table, see
"APPENDIX A – Device Data Blocks".

10.7 LCD setting

The variables to be displayed can be selected in two ways:
— Locally using the optional LCD keypad from the menu
"Display/settings/..." see APPENDIX B for further
information.
— From remote station via Fieldbus communication writing
in the HMITB.
In the HMITB there are up to 4 variables called HMI_
VARIABLE_x (where x is from 1 to 4) and each of them can be
set with one variable to be displayed, selected from a list of 10
different variables.
Then the HMI_LINE_1, HMI_LINE_2 and HMI_BARGRAPH
must be set to one of the HMI_VARIABLE_x depending by
which variable the user wants see on the Line 1 or Line 2 or
bar-graph. The parameter HMI_SEQUENCE allows the
enabling of the automatic scrolling of the 4 HMI_VARIABLE_x
Important.
HMI_MODE set to One Line..

10.8 HMI as Diagnostic Indicator

While the HMI works as Variable Indicator, also diagnostic
strings can be displayed. Whenever a failure or warning
condition is detected within the transmitter, a message appears
in the low side of the display below the bar-graph.
The message is formed by the NAMUR NE107 icon and the
string of the component where the problem occurred.
