4.10.4.1.1.2 Completion Data Point
A variable from the control application is connected here. This variable must already exist in
the control application in order to be assigned or input directly, i.e. already entered in the
variable declaration section.
Pressing this button opens the variable selection dialog box where an existing variable from
the control application can be assigned. By default, only variables with suitable data types
are displayed in the dialog box.
Depending on the function, one or more values can be defined which are assigned to the
key according to function and key status.
A variable can optionally be connected which allows a user−defined value to be set when then key action has
been completed.
The completion data point can be used to centrally record and query changes in the control application. In this
way, application code is created easier and is better maintained.
4.10.4.1.2 Set USINT and Set UINT
If a key is defined with the 'Set ...' function, then the connected variable is set to the defined value when the key
is pressed. The value has to be reset in the control application.
The same settings apply to both variations. Only the data types are different.
4.10.4.1.3 Toggle USINT and Toggle UINT
This function switches the status of the connected variable between 2 predefined values. This allows application
software functions to be switched on or off.
