3.2.3.1 Numeric Output Field − Reference<br />

This field allows data to be output in numeric form.<br />

This output field allows the system date and time to be output. A series of fixed,<br />

predefined output formats are provided to do this. If these do not suffice, formatting<br />

can be configured in the control application and an output string can be used. This is<br />

also necessary to display other, different date and time information.<br />

This field allows text to be output based on a numeric index read from a process<br />

variable during visualization runtime. This provides a simple way to switch between<br />

a predefined number of texts.<br />

This output field allows numeric data to be output in the form of a movable bar<br />

graph. By default, bar graphs do not have any borders or other embellishments.<br />

These can be added easily as needed in the <strong>Visual</strong> <strong>Components</strong> project.<br />

Using this output field, a list of texts can be shown on the screen underneath one<br />

another. They can be used either from a text group or a process variable. A text can<br />

be highlighted and selected using a process variable.<br />

If more texts are defined in the text group or the process variable than there is<br />

space set in the ListBox output field, then a corresponding excerpt is displayed. This<br />

ensures that the selected highlighted text is always visible.<br />

The ListBox output field doesn't allow user interaction, either from panel keys or<br />

touch screen keypads. Thus, any necessary operations need to be implemented in<br />

the application.<br />

This field allows a bitmap graphic to be output depending on a numeric value read<br />

from a process variable during runtime. In this way, predefined bitmaps can be<br />

output depending on a process variable value.<br />

General<br />
