METHOD FOR OPERATING A FIELD DEVICE USED IN PROCESS AUTOMATION TECHNOLOGY

Abstract

The disclosure relates to a method for operating a field device used in process automation technology, wherein the field device has an NFC/RFID transponder, wherein an operating unit comprises an operating system which has an executable operating program, in particular application software, wherein the operating unit has an NFC/RFID reader. The method is characterized in that the NFC/RFID transponder comprises a memory which has data which, when read out using the NFC/RFID reader, triggers the calling up of the operating program in the operating unit.

Claims

1-8. (canceled)

9. A method for operating a field device used in process automation technology, wherein the field device has an NFC/RFID transponder, wherein an operating unit comprises an operating system which has an executable operating program, in particular application software, wherein the operating unit has an NFC/RFID reader, characterized in that the NFC/RFID transponder comprises a memory which has data which, when read out using the NFC/RFID reader, triggers the calling up of the operating program in the operating unit.

10. The method according to claim 9, wherein the field device has a first communications interface for connecting the field device to a wireless communications network, wherein the operating unit has a second communications interface for connecting the operating unit to a wireless communications network which is accessible to the operating program, wherein the data triggers a wireless connection between the field device and the operating unit via the operating program.

11. The method according to claim 9, wherein login data are necessary for the wireless connection between the field device and the operating unit, wherein the login data are stored in the NFC/RFID transponder and read out using the NFC/RFID reader.

12. The method according to claim 11, wherein new login data are created by the operating program after each connection, wherein the new login data are transferred to the NFC/RFID transponder by means of an NFC/RFID writing unit, wherein the login data already stored in the memory are replaced by the new login data.

13. The method according to claim 12, wherein the login data have a first encryption, wherein the login data are decrypted by means of the operating program.

14. The method according to claim 13, wherein the login data are encrypted by means of the operating program so that the encrypted login data have a second encryption that replaces the first encryption, wherein the login data are transferred with the second encryption to the NFC/RFID transponder by means of an NFC/RFID writing unit and are stored there.

15. The method according to claim 9, wherein, in the event of a deactivated, second communications interface, the data trigger an activation of the second communications interface via the operating system.

16. The method according to claim 9, wherein, in the event of a deactivated, first communications interface, when reading out the data using the NFC/RFID reader, the operating unit triggers an activation of the first communications interface of the field device.

Description

[0059] The invention is explained in greater detail with reference to the following FIGURE. The following is shown:

[0060] FIG. 1: a flowchart of an embodiment of the method according to the invention for operating a field device.

[0061] FIG. 1 shows a flowchart of an embodiment of the method according to the invention. The operator brings his operating unit—in this case, his smartphone—closer to the field device (step 1). If the field device is located at a distance from the field device sufficient for the NFC/RFID transponder installed in the field device to be detected by the smartphone (step 2), the data stored in the memory is simultaneously read out by the NFC/RFID reader (step 3). The operating system interprets and executes the read data, which triggers a start of the operating program—in this case, the application software (step 4). The read-in data additionally comprise a UUID and login information or login data. With this information, the field device in the communications network is selected (step 5), and the operating unit is logged in (step 6). A wireless connection is created upon successful login (step 7). In the event of a successful connection, the application software switches to the main page of the field device (step 8). Previously, all of these steps had to be performed by the operator. According to the invention, the execution of the individual steps is triggered or initiated by the data stored in the field device.
