The Objects
Chapter 10
10-57
Like many objects, bar graphs can be grouped together with other objects
to create a fully functional “template”. For example, you can position two
or three bar graphs together and put numeric display objects immediately
below the bar graphs to display the process variable, set point, and control
variable. You can use any of the numeric entry functions interactively with
these values. You can also draw a box around the entire group of objects.
After sizing the bar in PanelBuilder, you assign a PLC input or output
address and a “data range”: a low and high value is assigned. If the value is
less than the lower limit, the bar will have no size. If the value is greater
than the upper limit, the bar will be full size.
The data range that can be displayed is 0 to 99,999,999 but the actual value
will depend on the data type and the address size. Available data types for
bar graphs are BCD, bit and integer. Negative numbers will be displayed as
0 bar size.
For example, with a data range of 0 to 4095, a data value of 2047 would be
at 50% of the scale. Another example: with a data range of 100 to 200, a
data value of 125 would be at 25% of the scale.
The resolution of the bar movement will be 10 pixels per character
vertically and 8 pixels horizontally.
To have a bar graph change color at certain values, cascade bar graphs
together: place the high end of one graph at the low end of the next, and
adjust each graph’s data range accordingly.
There are two objects that allow the display of time and date information:
the time display and the date display. There can be only one time display
and one date display per screen.
Time Display
The Time Display displays the current time at a specified location on a
screen. The time is displayed in the format hh:mm:ss (hours, minutes,
seconds). You can enclose the time display in a box for added emphasis.
Use the PanelView terminal’s Configuration Menu or the PLC Controlled
Time & Date option (under Options in the File menu) to set the correct
time on your PanelView terminal. The Configuration Menu can also be
used to set the time to appear in 12-hour (AM/PM) or 24-hour format.
