A device for securely operating a field device includes: the field device, which includes at least one human-machine interface having a display device and a keyboard for operating the field device, and a communications interface for connecting a local operating device having a secure connection to a trusted server via a communications network, the secure connection being based upon an authentication feature of a local operator. The field device during use as intended does not have a secure connection to a network for process control. The field device provides and stores a query key. The field device is connected, at least logically, to the local operating device. The trusted server has a private key for providing a signed response key. The signed response key is based upon the query key.

Method and device for securely operating a field device

System and method for maintenance support for electronically actuated and/or monitored appliances implemented within an electronically networked automation system, having a central monitoring unit processing present operating parameters for appliances for establishing the servicing state of the appliances using comparison operating parameters, where an external SSIS server logically combines the servicing request established by the monitoring unit with appliance-specific servicing performance information stored in a database and forwards these data to electronic mobile terminals of the servicing personnel in order to perform the servicing.
