Publication number: 20230370977Abstract: A method for regulating transmission of a plurality of industrial devices in a first section of an industrial facility is disclosed. The method includes measuring radio signal strength at a first location in the first section and comparing the measured radio signal strength against a predefined threshold associated with the first location in the first section. The radio signal strength is associated with one or more signals transmitted by at least one industrial device of a first wireless network in the first section. The comparison of the measured radio strength against the predefined threshold is performed for transmitting a message to the industrial device. Based on the message, the at least one industrial device is configured to adjust at least one transmission parameter of the industrial device.Type: ApplicationFiled: September 9, 2021Publication date: November 16, 2023Inventors: Martin Meyer, Siegfried Richter, Ulrich Sinn, Christoph Weiler, Mattias Lampe

Publication number: 20090047927Abstract: There is described a method for operating a radio network for transferring data between several subscribers, in particular, between devices of process instrumentation in an automation system. At least one first subscriber communicates in a telegram the requests thereof relating to the frequency of the data transfer to other subscribers in a starting phase. During network optimization, a configuration device determines, in the radio network and according to the frequency of the requests of other subscribers, at least one communication partner to which a connection comprising the frequency of the data transfer, which is adapted to the other subscribers, is established. As the periods of data transfer are planned, it is possible to switch off the communication interface of the first subscriber in the pauses and also, to save energy.Type: ApplicationFiled: December 13, 2006Publication date: February 19, 2009Inventor: Christoph Weiler
