TIP:

The “Configure” button opens the ⮫ “Dialog: Input Configuration ”, ⮫ “Introduction” dialog. There you can create or edit user inputs.

Configured user inputs are listed below the events. They each include the action that is triggered and the setting in short form.

Example: “Execute ST Code”: ‎PLC_PRG.i_x := 0;‎

“OnDialogClosed”

Input event: The user closes the dialog.

“OnMouseClick”

Input event: The user clicks the mouse button completely in the element area. The mouse button is clicked and released.

“OnMouseDown”

Input event: The user clicks down on the mouse button.

“OnMouseEnter”

Input event: The user drags the mouse pointer to the element.

“OnMouseLeave”

Input event: The user drags the mouse pointer away from the element.

“OnMouseMove”

Input event: The user moves the mouse pointer over the element area.

“OnMouseUp”

NOTE:

This CODESYS-specific triggering behavior guarantees that actions for key elements are completed. A key element starts an action for “OnMouseDown” and ends the action for “OnMouseUp”.

Example: A visualization user presses the mouse button within the element area of the key element and then moves the cursor position so that it is located outside of the element area. The action is ended anyway because “OnMouseUp” is triggered.

“OnValueChanged”

Event which triggers follow-up actions due to a change in value

Which follow-up actions are triggered is configured in the “Input Configuration” dialog.

The defined follow-up actions and the corresponding configuration are displayed below the element property.

The “OnValueChanged” event can be disabled by the “VISU_NO_VALUECHANGED” compiler define in the properties dialog of the application.

“Tap”

When a mouse click event occurs, the variable defined in “Variable” is described in the application. The coding depends on the “Tap FALSE” and “Tap on enter if captured” options.

“Variable”

Requirement: The “Tap FALSE” option is not activated.

Variable (‎BOOL‎) for the mouse click event

‎TRUE‎: A mouse click event exists. It lasts as long as the user presses the mouse button over the element. It ends when the button is released.

‎FALSE‎: A mouse click event does not exist.

Example: ‎PLC_PRG.bIsTapped‎

“Tap FALSE”

: The mouse click event leads to a complementary value in “Variable”.

‎TRUE‎: A mouse click event does not exist.

‎FALSE‎: While the mouse click event exists.

“Tap on enter if captured”

: During user input, it is also taken into consideration whether the mouse pointer is dragged within the element area or not while the mouse button is pressed.

‎TRUE‎: While the mouse click event exists and the mouse pointer is moved over the element area.

‎FALSE‎: A mouse click event does not exist. Or the user moves the mouse pointer outside of the element area while the mouse button is pressed.

The value is ‎TRUE‎ again as soon as the user moves the pointer back to the element area. The mouse is then captured.

“Switch over”

With the onset of a mouse click event, the variable is set; when the mouse click event is completed, the variable is reset.

“Variable”

Variable (‎BOOL‎) for toggling at the end of the mouse click event

This is when the user releases the mouse button while the mouse pointer is over the element area. If the user releases the mouse button while the mouse pointer is outside of the element area, then the mouse click event is not ended and the value is not toggled.

TIP:

The user can cancel a started toggle input by dragging the mouse pointer out of the element area.

“Toggle on up if captured”

: The value toggles regardless of where the mouse pointer is when the mouse button is released. The mouse is then captured.

“Hotkey”

Shortcut on the element for triggering specific input actions

When the hotkey event occurs, the input actions in the “Events” property are triggered. In this way, it is not the input action itself that leads to this input action, but the mouse input action.

“Key”

Key pressed for input action.

Example: [T]

The following properties appear when a key is selected.

“Events”

“Switch over”

: Combination with the "Shift" key

Example: [Shift]+[T].

“Control”

: Combination with the "Ctrl" key

Example: [Ctrl]+[T].

“Alt”

: Combination with the "Alt" key

Example: [Alt]+[T].
