An arrangement has a technical system, in particular a safety-related system, and a control device which controls the system and can change the technical state of the system by use of control commands. An interface device to be connected to the control device is provided. The interface device forms an external interface for connection to an external remote query device. The interface device has a checking device which is configured in such a manner that it checks a received remote query signal for the presence of a query command stored as permissible in the interface device. In the event of permissibility, the interface device forwards only the query command to the control device and blocks the forwarding of the remote query signal as such or all other control commands which are not query commands stored as permissible.
