Tag as the front face name by using the mnemonic DISPTAG on Line 1, as shown in the
figure above.
The Initial display state field is used to designate the script used initially by the display
block. In most cases it will be DEFAULTS. If a script is not used, or if the display state
is DEFAULTS, this field is left blank. Display States are described in more detail in
Chapter 4.
The bottom section of the page is used to define how the front display will look initially,
since it is possible to change this dynamically by means of scripts. The Line numbers
refer to the lines on the front display. Figure 10 shows the line numbers, which are
numbered the same for any display.
Figure 2 .11.
Display Elements
There are three columns to define the alphanumeric lines on the display. Lines 1, 2 and 6
may be up to eight characters long; lines 3, 4 and 5 may be up to 3 characters long. To
initially display a fixed value or text string, enclose the value or text in double quotes, for
example, “OP”. This may be dynamically changed during operation using scripts. To
display the value of a signal from another block (for example, process value from a PID
block) enter the mnemonic for that attribute.
The second page of the Display Block defines the bargraphs and highlighted segments.
Up to four intensified segments may be defined for each bar. This is useful for showing
various alarm trip-points, or using the display as a three-point indicator with the
intensified segments as setpoint values. As with the alphanumeric lines, these may be a
constant value, or tied to an input. The next figure shows the Bars tab of the Display
Block.
