A drive, method and a device for determining the torque of a shaft, wherein gear wheels engaged with one another in a gearbox serve to apply an axial force to the shaft, where the axial force is induced by helical teeth of the gear wheels, the axial force of the shaft is determined using a force sensor and/or a position sensor, and where the torque is determined arithmetically from the measured axial force such that a static and dynamic measurement of the torque on the shaft can be advantageously performed.

Method and device for determining torque exerted on a shaft including transferring torque to a gearbox by the shaft and exerting axial force on the shaft dependent on the torque exerted by the shaft to the gearbox

A method for transmitting real time data packets in a cyclic communication system, each transmission cycle having a first partial cycle (IRT-Z) for a real time communication portion and a second partial cycle (NRT-Z) for a non-real-time communication portion. The method includes determination () of a cycle number and processing of a transmission sequence of real time data packets in the first partial cycle. The transmission sequence is composed of one or more partial sequences (1, 2, 3, 4, 5), and the composition depends on the cycle number.

A method for receiving data messages in communications systems having redundant network paths. Received data of a peripheral representation or image is routed to a node along at least two different network paths. This makes it possible to store a consistent peripheral representation or image in a memory () of a node, if there is a disturbance in the data transmission along one network path.

A method for arbitrating access to a data bus among subscribers or bus devices (Tn,Tn, . . . ), wherein the bus devices are coupled by at least one arbitration ring (). The method comprises the following steps: a) requesting access by a first bus device; b) checking whether a first signal, which indicates that the arbitration ring is enabled, is present at an input () of the first bus device; c) if the first signal is present, outputting () a second signal by the first bus device; d) checking whether, at the end of a predetermined time period, the first signal is still present at the input () of the first bus device; and e) if the first signal is still present at the end of the predetermined time period, accessing the data bus by the first bus device.
