Abstract

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.
