Publication number: 20250138503Abstract: A method for identifying a field device for automation technology includes providing an operator unit, which includes at least one order ticket with an access authorization for at least one of the field devices. The method also includes searching for accessible field devices with the operator unit using a wireless communications protocol. For each of the field devices accessible from the operator unit, a temporary communication connection between the operator unit and the relevant field deices is established using a wireless communications protocol, the order ticket is transmitted to the relevant field device, the access authorization for validity is checked by the field device, and the field devices that were able to successfully carry out the check for the validity of the access authorization are signaled.Type: ApplicationFiled: October 24, 2024Publication date: May 1, 2025Inventors: Martin Lohmann, Thomas Alber, Oliver Durm, Roman Griesser, Björn Haase, Stefan Robl, Karsten Traub

Publication number: 20250139222Abstract: A method for operating a field device between an operating unit and the field device includes creating an order ticket using a ticket server. The order ticket contains an authorization for the operating unit to carry out defined tasks on the field device and information on the temporal validity. The method also includes transferring the order ticket to an operating unit and to the field device. The operating unit is registered with the field device if the field device verifies the order ticket is valid. If the order ticket is successfully verified, execution of the tasks defined in the order ticket on the field device is authorized for a predetermined period of time, which has an end point that is determined by the information on time validity contained in the order ticket. The authorization is automatically terminated by the field device after the predetermined period of time has elapsed.Type: ApplicationFiled: October 29, 2024Publication date: May 1, 2025Inventors: Thomas Alber, Oliver Durm, Roman Griesser, Björn Haase, Martin Lohmann, Stefan Robl, Karsten Traub

Publication number: 20250131349Abstract: A method for integrating a field device into an operating system is provided. The operating system includes a ticket server communicating with a transport medium. The ticket server and existing field devices process tickets, which contain a cryptographically secured item of information and transmit the created tickets to the transport medium, where the transport medium transmits the tickets to the recipient(s) and the recipient(s) check(s) the authenticity and integrity of the tickets. The method includes placing an order for the field device and generating registration data by a manufacturer's server. The registration data comprise identification information of the field device and a first cryptographically relevant item of information. The method also includes registering the field device as an existing field device on the ticket server. The registration data are transmitted to the ticket server and a second cryptographically relevant information of the ticket server is stored in the field device.Type: ApplicationFiled: October 16, 2024Publication date: April 24, 2025Inventors: Björn Haase, Thomas Alber, Oliver Durm, Roman Griesser, Martin Lohmann, Stefan Robl, Karsten Traub

Publication number: 20250119306Abstract: A method for verifying a first time recording unit of a field device that supplies the field device with a first date and/or a first time. The method includes receiving a ticket at the field device that comprises cryptographically secured information and a time stamp. The time stamp is obtained from a second time recording unit and contains a second date and/or second time. The method includes carrying out a trust assessment of the time stamp, wherein the trustworthiness of the second time recording unit is checked against the first time recording unit. If the trust assessment shows that the second time recording unit is more trustworthy than the first time recording unit, the method includes comparing the first date or the first time with the second date or the second time, and creating a warning message if a deviation greater than a predetermined factor is determined.Type: ApplicationFiled: October 9, 2024Publication date: April 10, 2025Inventors: Björn Haase, Thomas Alber, Oliver Durm, Roman Griesser, Martin Lohmann, Stefan Robl, Karsten Traub

Patent number: 11187673Abstract: The present disclosure relates to an apparatus the for verification, calibration, and/or adjustment of a measuring instrument. The apparatus includes the measuring instrument, a reference measuring instrument, and a smart device. The apparatus performs a measuring operation in which the measuring instrument determines a value of a variable of the medium and the reference instrument determines a reference value of the variable from a sample of the medium. The measuring instrument communicates wirelessly and performs the verification, calibration, and/or adjustment on the basis of the measured value and the associated reference value. The reference measuring instrument is portable and communicates wirelessly with the smart device and the measuring instrument. An application executed on the smart device controls a data transfer between the measuring instrument, the reference measuring device, and/or the device that is required for executing the verification, calibration, and/or adjustment.Type: GrantFiled: April 23, 2019Date of Patent: November 30, 2021Assignee: Endress+Hauser Conducta GmbH+Co.
