The different available parameters
The adjustable parameters of the digital input interfaces are the same as these of the 'General Interfaces'. Depending on the selected interface, the following parameters can be added in the 'Button' field:
- Invert Input
- when this parameter is marked with a 'V', the input will work inverted. So the central unit is not taking action when the contact is closed (for most of the functions) but when the contact opens.
This is most often used when a NC (Normally Closed) contact is connected to the input.
- Edge triggered
- when this parameter is marked with a 'V', the 'short' and 'long' names will change into 'on closing' and 'on opening'.
- On closing
- the coupled action is processed at the moment that the contact closes and for as long as the contact remains closed (or the button remains pushed in case of a normal open contact).
- On opening
- the coupled action is processed on the moment that the contact opens or the button is released (in case of a normal open push button contact).
