Abstract

A method for the start-up of a numerical control of machine tools or production machinery, wherein the numerical control includes a main computer and a follow-up device, which are connected with each other via a data transmission network, wherein the follow-up device is addressable by the main computer via a logical address and a hardware address, with information regarding a physical address of the follow-up device in the data transmission network, is allocated to the logical address. The method includes sequentially requesting in a set-up mode of operation of the main computer allocating information regarding a logical address and a hardware address from an operator for the follow-up device and other follow-up devices to whose logical address no hardware address had been allocated. The method further including storing the logical address and the hardware address in a memory unit after the allocating information has been performed.
