Visible Fields

Has Valid Input

name: validInput, type: Bool, persistent: no

Has Valid Output

name: validOutput, type: Bool, persistent: no

Update automatically

name: autoUpdate, type: Bool, default: FALSE

If set, the output will always get the same value as the input, but only after the input has been touched first. If not set, any touching of the Base input field will set the output to NULL. Unnecessary notifications will be suppressed.

Update

name: update, type: Trigger

Update the output Base field to the input Base field’s value. This will always trigger a notification on the output field.

Clear

name: clear, type: Trigger

Set the output Base field to NULL. If the output field is already NULL, nothing will be done.
