Abstract
A field device apparatus is described which, for communicating with an evaluation device, can be operated in a direct or indirect operating mode, which both use the same access data.
Claims9
A field device apparatus comprising:
- a measuring device;
- a communications device;
- wherein the measuring device is configured to determine a measurement value and to communicate with the communications device;
- and
- wherein the communications device is configured to set an operating mode for connection to an evaluation device, which operating mode can be selected from a first operating mode and a second operating mode;
- wherein the first operating mode enables an indirect connection to the evaluation device via a communications network;
- wherein the second operating mode enables a direct connection to the evaluation device;
- wherein the indirect and the direct connection involves the use of same transmission technology;
- wherein the communications device is configured to selectively operate as an authentication client or an authentication server;
- wherein when the communication device operates as the authentication client, the communications device is configured to request access data and utilize the access data for logging onto the communications network in the first operating mode;
- wherein when the communications device operates as the authentication server, the communications device is configured to request the access data and utilize the access data for connecting directly to the evaluation device in the second operating mode;
- and
- wherein the communications device is configured to accept a connection request in the second operating mode.
