LCD structure

The Display DOT matrix is split in 4 rows each reserved to display different data:
The first row displays the Device TAG and Node Address and these data are always visible. The line/s and bar-graph view depend by
the HMI_MODE Selection Each variable is displayed together with its own identification string of max three characters, on the left
side of the values, when two lines mode is selected, or below the value when one line mode is selected.
The list of all the identification strings is available in the HMI_VARIABLE_1 within the HMITB table, see "APPENDIX A – Device Data
Blocks".
Example of how the indicator looks with One and Two lines plus bar-graph:
Figure 47: Display layout
During the normal activity, when the display is working as indicator, there are two special symbols/icons in the bottom corners of
the display associated to the buttons (1) and (4).
When they are pressed it is enabled their own function as follow:
• The Button (4) activate the display local device menu prompting the menu "Display"
• The Button (1) activate the display local operator menu

HMI Operations

The Local display is usable for different purposes.
• Variable Indicator
• Diagnostic Indicator
• Configuration tool
• Feedback of the local push button operations

HMI as Variable Indicator

This is the normal activity of the local HMI. It is refreshed every 2 seconds displaying the selected variables among those calculated
every loop in the PRTB as well as inside the Function Blocks of the transmitter.
The variables to be displayed can be selected in two ways:
• Locally using the optional LCD keypad from the menu "Display/settings/..." see HMI menu Structure 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 bargraph. The
parameter HMI_SEQUENCE allows the enabling of the automatic scrolling of the 4 HMI_VARIABLE_x
IMPORTANT
It is recommended to use the Auto-scrolling only with HMI_MODE set to One Line.
