Introduction to <strong>Visual</strong> <strong>Components</strong> 2.3<br />

4.6.4.1.3 Text Number Data Point<br />

Process variable which selects the text to be displayed at runtime. The current value of this process variable<br />

corresponds to the numbers of the texts in the text group. Whichever value the process variable holds will<br />

determine which text from the text group is displayed.<br />

If the process variable contains an invalid value, then this text field is displayed on the target system filled with<br />

asterisks (*). If the variable does not exist because the task has not yet been transferred to the controller, for<br />

example, then the error is indicated with dashes (−).<br />

4.6.4.1.4 Attribute Data Point<br />

A process variable which determines more details of the displayed text can be connected here. The variable<br />

must be of data type UINT and can indicate two states at this time.<br />

4.6.4.1.5 Status<br />

Effects<br />

Depending on the display used, text is output inverted (with reversed foreground and<br />

background colors) or blinking.<br />

Blinking is used on all displays which cannot display graphics. Text is inverted on all other<br />

displays including graphic displays with C130 CAN controllers.<br />

Allows the connection of a process variable which can influence the output field (see also Controlling Fields with<br />

Status Variables).<br />
