Display Layout
The Display DOT matrix is split in 4 rows each reserved to display different data:
Row 1 displays:
• Device TAG, as a string of 8 characters
• Status Byte displayed as textual or numeric format. The choice between text or decimal number is user selectable
from the parameter
“HMITB_NUM_STATUS_ENA” (index 36)
.
When textual format is selected, only the Quality of the Status byte is displayed as:
–
“GOODnc”
–
“GOODc “
–
“BAD “
–
“UNCERT”
When the numeric format is selected the code of the Status byte is displayed inside round brakets
i.e: (128) = GOODnc-non specific-not limit.
• Device Address, as detected in the live list of the FF bus.
Row 2
is reserved to the display a number of 5 digit with decimal point plus sign representing the measure received at
the selected input of the MAO block..
Row 3 displays:
• Variable TAG, as a string of 11 characters to identify the displayed measure.
• Unit code of the displayed measure as a text of 8 characters
• The user can write the Variable TAG and its unit code of each of the 8 MAO Block inputs. Refer to the parameters
“HMITB_INPUT x TAG” and “HMITB_INPUT x Unit” (indexes from 17 to 32)
where x goes from 1 to 8 identifying one of
the 8 MAO inputs.
Row 4 displays:
• Diagnostic error code of three digit size plus the NAMUR NE107 classification icon
• The MAO input actually selected with the additional indication if the value in input is coming from a linked source
upward block or variable i.e: “INxL” or if it is not linked but directly written to the MAO input i.e: “INxN” where x goes
from 1 to 8 depending by the selected input (i.e: IN3L or IN2N)
