Component For structured data types only.
One element of the structured variable is selected at a time from the
selection list. The operation of each component is configured separately.
In DigiVis the operation of the components is carried out one after
another.
write/don’t
write component For structured data types only.
Whether or not it shall be possible to operate a component in DigiVis is
specified here for each component..
Text for variable Input any text.
This text will be displayed in the operation dialog in front of the input field
or radio buttons and used as variable name in the operations log.
Dimension Input any text.
This text will appear after the input field in the operation dialog, and after
the old and new values in the operations log.
Fixed value Input is only possible here if fix operation has been chosen. DigiVis will
write this value directly to the process station without bringing up any
operation dialog.
continuous DigiVis will obtain the value using an input field and scroll bar..
discrete Up to 6 radio buttons will be used by DigiVis to obtain the value in a
dialog box..
Min/Max Value range for the scroll bar. If no range is configured, the scroll bar will
not be available for input.
Lock The operation of a value can be locked in conjunction with a BOOL
variable. When the operation dialog is called up, this variable is first read
and operation refused if it has a value of TRUE. Also, writing a fixed value
can be prevented by the configuration of a Lock variable.
negate The value of the variable defined in Lock is negated for the purposes of
locking out operation, i.e. to lock out operation, the variable must have a
value of FALSE.
