Safety-oriented electrical controller and controller system

An electrical controller, comprising:

• a first interface via which data are able to be transferred;
• a second interface, separate from the first interface, via which data are able to be transferred;
• a control unit;
• and
• an operating mode memory for storing operating mode information, the control unit being configured to operate the electrical controller in a first safety-oriented operating mode or in a second safety-oriented operating mode depending on the stored operating mode information, wherein
• the control unit in the first safety-oriented operating mode is configured to:
• receive and store a parameter set from a motion controller via the first interface,
• receive a Cyclic Redundancy Check (CRC) code, dependent on the parameter set, from a safety controller via the first interface,
• check whether the received CRC code corresponds to the received parameter set, and
• control the operation of the electrical controller depending on the received parameter set if the received CRC code corresponds to the received parameter set.
