Id #

The Id field shows the internal number of the interface under which it is saved. When creating a new interface, the field is empty. The type of interface is displayed behind it. Both parts are for information purposes only.

Name #

The name of the interface. The name is displayed in selection lists and may also be displayed to users in interface notifications.

Comment #

The comment field is for free use by the integrator. It is used exclusively to document the configuration. You can enter information here, e.g. the purpose of the interface, any special features, etc.

Options #

Here you will find a single checkbox: Deactivated. If you set this checkbox, the interface is deactivated as far as possible. Channels of the interface are still available in the system, but write accesses are no longer passed on to the hardware and read accesses return no value or the last available value.
Deactivating an interface can be helpful if the hardware is no longer connected/defective, or if you want to try something out without the physical devices being addressed.

Update #

Here you specify how often the data is updated.

Special features #

This interface cannot be completely deactivated, it can only switch to a read-only mode. If you set the deactivated checkbox, the interface will continue to supply data. However, it will no longer perform write accesses. To set up the channels for the system interface, perform an import on the system interface.

The system interface provides channels with system information and some predefined constants.
