Abstract: The invention relates to a method for processing consistent data sets by asynchronous application of a subscriber in an isochronous, cyclical communication system. According to the invention, by connecting a communication memory and a consistency, transmission and reception buffer, copying processes leading ti delay can be kept to a minimum.

Abstract: The invention relates to an electronic switching circuit for a scalable communications interface between a first communication connection (16) having a first transmission cycle (17) with a first length and a second communication connection (12) having a second transmission cycle (13) with a second length, and comprising a receiving list (5, 15, 19, 33) for the first transmission cycle and a sending list (6, 14, 18, 31) for the second transmission cycle, wherein an element of the sending list is assigned to a data message (20, 21, 22, 23, 24, 25, 26, 27, 28) received in accordance with the receiving list, and having a cut-through buffer memory (8, 35) for a data message received in accordance with the receiving list and a data message to be sent in accordance with the sending list.
