Positions
The short text and graphics text, as well as the I/O field and unit text, are each
treated like a unit, i.e., position settings for short text apply to the graphic text and
settings for the I/O field and to unit text.
The configured position entry overwrites the default value, i.e., only one value can
be changed.
If no position data is configured for following screen form elements, then the
position settings for the preceding screen form element are applied.
If no positions have been specified for any element, then default positions are
applied. The column width for the short text and I/O field is calculated as standard
for each line from the number of columns and maximum line width, i.e.,
column width = maximum line width/number of columns.
The width of the graphics and unit text is predefined and optimized to suit the
requirements of programming support. If graphics or unit text has been configured,
the width of the short text or I/O field is reduced accordingly.
The order of short text and I/O field can be reversed by position settings.
Variable parameter group 6)
Help
The Help loop for a screen form element can be extended or deleted during
runtime. These functions are available only with HMI Advanced.
Extending the Help loop:
ADDHTX (Identifier, Help file, Index, Help text)
where:
Identifier
Help file
Index
Help text
The Help loop can be extended as required by calling the function repeatedly.
ADDHTX(VAR1, "C:\OEM\HLP\MYHLP.PDF", 15, "Machine data")
Deleting the existing Help loop:
CLRHTX (Identifier)
where:
Identifier
