A method for the start-up of a numerical control of machine tools or production machinery, wherein said numerical control comprises a main computer and a follow-up device, which are connected with each other via a data transmission network, wherein said follow-up device is addressable by said main computer via a logical address and a hardware address, and wherein information regarding a physical address of said follow-up device in said data transmission network is allocated to said logical address, the method comprising:
- performing via said main computer the following:
- sequentially requesting, in a set-up mode of operation of said main computer, allocating information regarding a logical address and a hardware address from an operator for said follow-up device and other follow-up devices to whose logical address no hardware address had been allocated;
- said operator performing a task in response to said sequentially requesting that enables said main computer to allocate said hardware address to said logical address;
- upon said operator performing said task, said main computer allocating said hardware address to said logical address;
- storing said logical address and said hardware address in a memory unit after said allocating said hardware address to said logical address has been performed by said main computer;
- and
- outputting via said main computer said requesting for allocating information in a form of said logical address of said follow-up device to be allocated on a display screen;
- and
- said task comprising initiating transmission of said hardware address from said follow-up device to said main computer by said operator actuating an operating element at said follow-up device to be allocated.
