The process variable which should be manipulated after this touch field is activated is located in
the Source field.
The Assign... button opens a dialog box to select a variable with a suitable data type.
Possible Settings Name of a UINT process variable.
This value is written to the Completion Data Point process variable after each operation of the
touch field.
Possible Settings 0 − 65535
This setting defines whether the value range for the connected variable should be limited when
this touch field is used for input. If this option is enabled, input cannot be adjusted if it were to
violated the limits set under Limit Min. and Limit Max..
However, adjustments can be made if the value is already outside the limits and is being
adjusted in the direction of the valid value range. Regardless, adjustment takes places using the
set increment.
If this option is not selected, the process variable adjustment is limited by its data type. Thus it
cannot be adjusted beyond the extreme values and jump over the minimum and maximum
values (or vice versa).
This setting is only activated if Use Limits is selected. The setting defines the lower limit of the
allowed adjustment.
This limit only has an effect when a negative Increment is used.
Possible Settings Depends on the data type of the connected Data Point, but maximum
from −32768 to 32767.
This setting is only activated if Use Limits is selected. The setting defines the upper limit of the
allowed adjustment.
This limit only has an effect when a positive Increment is used.
Possible Settings Depends on the data type of the connected Data Point, but maximum
from −32768 to 32767.
This setting defines the increment which occurs each time the touch field is activated. If the
increment is positive, then the connected Data Point is increased; if the increment is negative,
then the connected Data Point is decreased.
Possible Settings Depends on the data type of the connected Data Point, but maximum
from −32768 to 32767.
If this option is selected, pressing and holding the touch field will continuously increase or
reduce the value by the set increment.
If this option is not selected, only one adjustment of the associated Data Point is caused
regardless of the length of time the touch button is pressed.
