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.
A method for data transmission between an encoder and a motor and/or actuator control unit via an insecure multi-channel channel, comprising the multi-channel channel is formed as a black channel that forms a non-secure transmission channel that is verified by a higher-level or downstream instance an additional security protocol is superimposed on the black channel comprising the non-secure protocol thereof, and t the security protocol transmits additional data, preferably relating to the integrity and security of the data transmitted via the black channel, to two mutually independent evaluation units which generate a verifiable redundancy that is evaluated in a downstream functional module.
A device for data transmission between an encoder and a motor and/or actuator control unit via an insecure multi-channel channel, an insecure channel connected to the output of an encoder-side interface or directly to the rotary encoder, which channel is formed as a two- or four-wire line and is connected to the input of a secure evaluation unit, the output of which is connected to the motor-side motor control unit.
The device according to claim, wherein the secure evaluation unit is arranged between in the motor control unit.
