Abstract
An apparatus for a safety-relevant application and a method for operating the apparatus. The apparatus has a user interface to display digits. The digits are intended to be filled with numerical values by a user. The user interface is designed to limit a selection of digits available for a user input when a numerical value is input by the user, for example the user's first input, for one of the digits that are to be filled.
Claims18
A method for operating an apparatus for a safety-relevant application, the method comprising:
- displaying, by a user interface, a predetermined number of fields for receiving an input numerical parameter;
- comparing at least one of the predetermined number of fields to at least one numerical limit or at least one other safety-relevant limitation to determine if the at least one of the predetermined number of fields may receive an input numerical parameter within the at least one numerical limit or at least one other safety-relevant limitation;
- limiting, by the user interface, the predetermined number of fields for receiving the input numerical parameter to a selection of fields that is less than the predetermined number of fields available for a user input of the input numerical parameter based on the comparing;
- and
- displaying, by the user interface, a numerical value provided by the user based on user selection of one of the selection of fields for receiving the numerical value.
An apparatus for a safety-relevant application, the apparatus comprising a user interface that displays a predetermined number of fields for receiving an input numerical parameter, wherein the user interface is configured to limit the predetermined number of fields for receiving the input numerical parameter to a selection of fields that is less than the predetermined number of fields available for a user input of the input numerical parameter based on a comparison between at least one of the predetermined number of fields and at least one numerical limit or at least one other safety relevant limitation and to display a numerical value provided by the user based on user selection of one of the selection of fields for receiving the numerical value.
