Abstract
A method for operating a field device is disclosed, the field device having settings and/or functions classified into different security levels, where one of the settings and/or functions of the field device is selected by a user, at least one security measure is implemented depending upon the security level with which the selected setting and/or function is associated, and the security measure determines whether the selected setting and/or function of the field device is released for the user.
Claims18
A method of operating a field device, the method comprising:
- selecting one of a plurality of settings and/or functions of the field device, the selecting being performed by a user, wherein the plurality of settings and/or functions of the field device are classified into separate security levels;
- executing at least one security measure, the at least one security measure depending upon the security level associated with the selected setting and/or function;
- and
- determining whether the security measure was executed successfully, wherein upon determining that the security measure was executed successfully, releasing the field device for the user.
An arrangement comprising:
- a field device having a plurality of settings and/or functions of a field device, wherein the plurality of settings and/or functions of the field device are classified into separate security levels and are selectable by a user;
- and
- an operator device operable by the user, wherein the field device and the operator device are configured to cooperatively enable the user to select one of the plurality of settings and/or functions of the field device, to execute at least one security measure, the at least one security measure depending upon the security level associated with the selected setting and/or function, and to determine whether the security measure was executed successfully, wherein upon determining that the security measure was executed successfully, releasing the field device for the user.
A computer program product comprising program code means that, when executed, serve to implement the program code configured to be executed on a field device, a server and/or an operator device to enable a user to select one of a plurality of settings and/or functions of the field device, to execute at least one security measure, the at least one security measure depending upon a security level associated with the selected setting and/or function, and to determine whether the security measure was executed successfully, wherein upon determining that the security measure was executed successfully, releasing the field device for the user, wherein the plurality of settings and/or functions of the field device are classified into separate security levels.
