Abstract:
A method for monitoring a field device connected via a data bus with a control unit. To prevent unauthorized tampering with the field device, the control unit requests, at intervals of time, an individual identifier of the field device. The requested individual identifier is compared with an identifier stored in the control unit. An alarm is produced or a warning, in the case of a change in the requested individual identifier.
