Abstract
The invention relates to a serial data transfer in a numerically controlled control system to update an output value of the control system. A variable write depth shift register is used to update an output value of the control system in such a way that only a number of bits of a data word, which has to be updated to form the updated output value via a serial data transfer is transferred to the variable write depth shift register, so that the output value is updated in a shorter time and can be updated more frequently. The variable write depth shift register is applicable in a numerically controlled control system in which long data words and shift register are used to update the output value via serial data transfer.
