5.21.6 Variant Options
Variant options are required if you want to
• implement a selection field to allow selection of variants in your
project
• allow the number of fractional digits (precision) to be influenced de-
pending on the variant used
• implement different user interface systems depending on the variant
used
The variant selection can be configured in the Variant Buffer area.
Enter the name of the variable for the variant buffer. In addition, you
need to specify the size of the buffer in bytes.
The maximum buffer size is 32 bytes.
The variant buffer is read only once during the initialization phase!
Using the variant buffer, you transfer a sequence of binary values to
the operating device in order to enable or disable elements of a variant
selection.
Example for variant selection In the Fractional Digit Control area, enter the name of the variable that
is used to define the number of places to follow the decimal point (frac-
tional digits) globally. For variables, it is possible to specify the follow-
ing for the formatting: fractional digits + offset or fractional digits –
offset. The offset is entered into this variable.
If 2 fractional digits are specified for variable display and the variable
for the fractional digit control contains the value '1', the following
applies:
for + offset - 3 digits after the point are displayed (XXXX.xxx)
for - offset - 1 digit after the point (XXXX.x).
Example for factional digit
control
In the Mask Reference List Control area, enter the name of the control-
ler variable you want to use to specify the mask number.
