Increasing and Decreasing the Process Variable
A process variable can be increased or decreased by a predefined amount using the actions described in this
section. Convenient up/down control of a value can be accomplished using a combination of two such touch
buttons. Up/Down control is internally limited by the INT16 data type. This means a maximum value of 32,768
and a minimum value of −32,767 are used for the limits.
The following additional settings are offered for this key type:
Key Type
Data Point
Completion
Data Point
Defines the action to occur for the touch field. The following actions are described in this

variable value will be increased or decreased by this amount each time
the button is activated.
An automatic iteration can optionally be chosen so that pressing and
holding the touch field adjusts the value quickly.
The process variable which should be manipulated with this touch field 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 process variable with one of the following data types: USINT,
SINT, UINT, INT, UDINT, or DINT.
After each operation of the touch field, a process variable of data type UINT can additionally be
set to a predefined value. This makes requesting and evaluating input and operations easier to
accomplish in the control application.
