摘要： A device driver comprises a device controller and a first encoder provides encoder data according to a first encoder protocol capable of being converted to an associated first controller protocol. In the device driver, encoder data conforming to a first encoder protocol is received, wherein: the first encoder protocol is not the same as a second encoder protocol, the second encoder protocol is capable of being converted to an associated second controller protocol that is not the same as a first controller protocol associated with the first encoder protocol, and the device controller is configured according to the second controller protocol. The encoder data is converted, according to at least one controller protocol conversion rule, into converted controller data conforming to the second controller protocol that is thereafter provided to the device controller.

摘要： A method for data transmission between an encoder and a motor and/or actuator control unit via an insecure multi-channel channel, the multi-channel channel being formed as a black channel that forms a non-secure transmission channel that is verified by a higher-level or downstream instance, wherein an additional security protocol is superimposed on the black channel, comprising the non-secure protocol thereof, and the secure protocol transmits additional data, relating to the transmission via the black channel, to two mutually independent evaluation units which generate a verifiable redundancy that is evaluated in a downstream functional module.

摘要： Method for digital, bidirectional data transmission between a position measuring system (3-7) and a motor control device (1) and/or an evaluation unit based on the transmission of frames (34, 35, 36) of a predefined bit length in chronologically sequential time slots (28-30), wherein a primary master (1) communicates via a two wire bus line (2) with the position measuring system (3-7) and/or the motor unit (11, 14) and/or the evaluation unit with a primary slave (3) disposed there, and that additional sub-slaves (12, 15) can be coupled in parallel to the primary slave (3), which sub-slaves communicate on the same bus line (2), which the primary master (1) uses with the primary slave (3).
