    摘要： It is described a method for transition of control from a first controller (101) to a second controller (103), the method comprising: communicatively coupling (143, 145) the first controller and the second controller, such that at least one static digital input signal (110) received by one controller (101) is mutually provided to the respective other controller (103) and such that at least one static digital output signal (118) generated by one controller (101) is mutually provided to the respective other controller (103); disconnecting at least one output line (124) from the first controller (101); connecting the at least one output line (126) to the second controller (103); supplying at least one output signal (147) to the at least one output line (126), wherein the at least one output signal (147) is obtained by performing a logical OR, in particular using an OR-gate, to at least one first output signal (118) generated by the first controller (101) and at least one second output signal (136) generated by the second controller (103), the method further comprising before disconnecting at least one output line (124) from the first controller (101): supplying a logical high signal to the output line by an external voltage source, if the first output signal (118) is a logical high signal or if the output line is at a logical high state during normal operation.
