CONSTRAINED OPERATION OF A FIELD DEVICE

The present application relates to a method for operating a field device (101). The field device (101) is configured for interacting with a control device (102). According to the method, a base key is received (201) from a key generation device (103). A current constraint parameter relating to a pre...

Zusammenfassung:	The present application relates to a method for operating a field device (101). The field device (101) is configured for interacting with a control device (102). According to the method, a base key is received (201) from a key generation device (103). A current constraint parameter relating to a predefined operating constraint for operating the field device (101) is determined (202). A key is generated (204) based on the base key and the current constraint parameter. The field device (101) interacts (205) with the control device (102) using the generated key.
