4.6.2 Displaying Texts and Numbers<br />

<strong>Visual</strong> <strong>Components</strong> offers a series of output fields for displaying text or numeric values. Depending on the<br />

output field, various display possibilities exist for representing process variables of different data types.<br />

The following value and text outputs are supported by <strong>Visual</strong> <strong>Components</strong>.<br />

• Numeric Output<br />

All numeric process variables, regardless if they are integer or floating point data types, are displayed<br />

using the universal Output Numeric field.<br />

• Text Output<br />

Character strings which are stored in process variables on the controller can be displayed in the<br />

visualization application as text. Any character from the font being used can be displayed. Text output is<br />

displayed using the Output String field.<br />

• Date and Time Output<br />

An Output Date/Time field is available which also allows appropriate display formatting. If the format for<br />

this output field does not suffice, then a string with date or time information can be entered in the control<br />

application and displayed as text output.<br />

Additional possibilites for displaying texts from a text group or a graphic bitmap − depending on a numeric<br />

process variable − are described in the Text and Graphics Output Using an Index section.<br />

Size, format, output field position, and the connected process variable can all be configured under the<br />

'Parameter' tab.<br />
