Abstract
The present disclosure includes a method and a system for remote-controlled servicing of a field device of process automation, including establishing a communication connection between a service unit and the field device via a first network, sending via a second network an access request from a computer unit to an application program executed on the service unit, wherein the application program serves for servicing the field device, approving the access request via the application program, and establishing access of the computer unit to the application program via the second network upon approval of the access request, wherein, after established access, the servicing of the field device occurs from the computer unit.
Claims17
A method for remote-controlled servicing of a field device of process automation, comprising:
- establishing a communication connection between a service unit and the field device via a first network;
- sending via a second network an access request from a computer unit to an application program executed on the service unit, wherein the application program enables servicing of the field device;
- approving the access request via the application program;
- establishing access of the computer unit to the application program via the second network upon approval of the access request;
- obtaining an image of the application program on the computer unit;
- and
- after establishing access, servicing the field device from the computer unit by making input to the image of the application program on the computer unit, processing the input by the application program of the service unit and taking a corresponding action on the field device by the service unit.
A system for remote-controlled servicing of a field device of process automation, comprising:
- at least one field device of process automation;
- a service unit on which an application program for servicing the field device and/or for displaying process and/or diagnostic data of the field device is implemented and executed, wherein the service unit communicates with the field device via a first network;
- and
- a computer unit embodied such that the computer unit communicates with the service unit via a second network and accesses the application program of the service unit such that the computer unit services the field device via the application program, wherein an image of the application program is obtained on the computer unit, and wherein the field device is serviced from the computer unit by making input to the image of the application program on the computer unit, processing the input by the application program of the service unit and taking a corresponding action on the field device by the service unit.
