Digital Input interfaces – Specific parameters

The different available parameters

Image123
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).

When an input works ‘Edge triggered an ‘Extra function’ tab will be available on which a second ‘on closing/on opening’ pair of functions can be defined.

Remark: For some functions the ‘Edge triggered’ option is automatically set e.g. motion detector functions, transparent functions, … In these cases the ‘Edge triggered’ option cannot be cleared.
