Abstract: The invention relates to a method for transmitting data via a communications channel (106), in which the data is transmitted with a transmission frame, wherein the transmission frame has at least one prioritisation field (PCP) for establishing the priority of the message and a data field, wherein the prioritisation field (PCP) functions to control the bus access by prioritising the messages. For this purpose, a bus access controller is used, in which the priority of at least the last received data packet is stored in a minimum priority storage cell (330). After receiving a data packet, a timer (320) is started, for which a timeout value is set, which is reset when a following packet is received. After reaching the timeout value, a decrementing of the value stored in the minimum priority storage cell (330) occurs.

Abstract: A method for transmitting data via a serial communication bus where the data are transmitted with an adapted transmission frame. The adapted transmission frame includes at least one arbitration field and a data field, with the arbitration field being used to control the bus access in accordance with the Carrier Sense Multiple Access with Collision Resolution method by prioritization of messages with the aid of an identifier. For the arbitration phase, a low bit rate is set; and an increased bit rate is set for the transmission of the data in the data field. A start field is provided in the transmission frame. The data are packaged as an Ethernet transmission frame, which is inserted into the data field of the adapted transmission frame. The arbitration field and the start field replace a preamble and a Start Frame Delimiter of the Ethernet transmission frame.

Abstract: An extension of the existing CAN FD data transmission protocol. The extension enables the use of the IPv6 protocol for the CAN bus. The CAN FD protocol is further developed in an incompatible way. One modification measure relates to the lengthening of the Data Field, which is positioned in the transmission frame after an Arbitration Field. An arbitrary number of bytes can be entered in the extended Data Field within a specified upper limit. Since the Data Field is transmitted at a higher bit rate field than the Arbitration Field, the data throughput is increased dramatically.

Abstract: A multi-row dough-portioning apparatus has a chamber housing having a number of portioning chambers for predetermining a portioned quantity of dough. Measuring pistons can each be displaced in the portioning chambers along a displacement direction between a retracted, measuring position and a pushed-out, ejecting position. A rotation-prevention bar is installed in a releasable manner on a rear wall of the chamber housing and interacts with a circumferential recess in the measuring pistons in order to prevent rotation of the same. The chamber housing has a projecting section, which projects beyond the rear housing wall. The rotation-prevention bar is installed on the chamber housing such that, upon release, it can be removed from the chamber housing in a removal direction perpendicular to the displacement direction of the measuring pistons. This results in a dough-portioning apparatus which, even in the case of large-volume portioning chambers, is easy to maintain and clean.
