> Data type “text” (analog output, see also: Function block TEXT)
Data type “text” can be used for display of indexed texts for analog integer signals. Moreover, an analog value can be
allocated to a text when adjusting.
w The corresponding input must be connected with the index output of a text block.
w The number of the text to be selected (VWERT output Y1...Y6) is applied to the index input of the first (next to
VWERT) text block.
w The text blocks cascaded by wiring the index output of another text block with the Casc input of the relevant text
block. Text selection is always via the index input of the text block next to VWERT.
w Via the UsrLan input, text blocks of different language can be appended. Language switchover (language index) is
defined by the value at the UsrLan input of status block 98. Unless an appropriate text block for the language is
available (e.g. language index too high), the corresponding text is output in the last language block found.
w When selecting a text in the VWERT to be displayed, the number of selectable texts is limited by the number of
connected text blocks.
w If the index for text selection comes from a different origin, no text is displayed if the index is beyond the possible
text selection ( 0 or >max ). VWERT marks the line with “————————“.
w With text selection at VWERT, the initial value ( parameter Y1...Y6) should be set > 0 to avoid a start value of
“————————“ .
y Data type “menu”
Data type “menu “ can be used for changing to other operating pages (menu without sub-menu items,
linking not possible).
w The value applied to the corresponding input is interpreted as block number of the operating page to which
changing is required.
w Changing to the specified page is done by pressing the Enter key. Unless the page is accessible, a change to the
operating page selection list is made. This list contains all the blocks which are available for selection .
If a page is not accessible, the reasons may be:
1. Block number not defined
2. Block number does not have an operating page
3. Block cannot be displayed instantaneously because hide = 1 .
w When making a standard exit from the operating page, return is to the calling VWERT page.
w When using this procedure for changing to a VWERT operating page which also contains a menu type line, no fur -
ther change will occur.
