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.

Claims

1. 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, with information regarding a physical address of said follow-up device in said data transmission network, is allocated to said logical address, the method comprising:

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; and

storing said logical address and said hardware address in a memory unit after said allocating information has been performed.

2. The method in accordance with claim 1, further comprising:

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

initiating transmission of said hardware address from said follow-up device to said main computer by actuating an operating element at said follow-up device to be allocated.

3. The method in accordance with claim 1, wherein said requesting said allocating information takes place by having said main computer switch on a signal unit of said follow-up device to be allocated by using said hardware address and outputs a list of logical addresses on a display screen, from which selection of said logical address belonging to said follow-up device with said switched-on signal unit is performed on said display device.

4. The method in accordance with claim 1, further comprising signaling from said main computer allocation of said logical address to said hardware address by activating a signal unit of said follow-up device.

5. The method in accordance with claim 1, further comprising:

requesting said allocating said hardware address by having said main computer output said logical address of said follow-up device, as well as a list of hardware addresses of other follow-up devices to which no logical address has yet been allocated, on a display screen; and

sequentially selecting said hardware address from said list;

switching on a signal unit of said follow-up device based on said sequentially selected hardware address until allocation is detected by said switched-on signal unit to be allocated and confirms it to said main computer.

6. The method in accordance with claim 1, wherein said hardware address contains a bus address, which provides a position of said follow-up device in said data transmission network.

7. The method in accordance with claim 6, wherein said hardware address further contains an identifier, which unequivocally identifies said follow-up device.

8. The method in accordance with claim 1, further comprising switching on said numerical control, wherein during said switching on said numerical control said main computer checks whether every logical address has been allocated a hardware address and, in case of determining not every logical address has been allocated a hardware address, switching into said set-up mode of operation.

9. The method in accordance with claim 1, wherein said information allocated with said hardware address is stored in the form of a parameter data set.

10. The method in accordance with claim 1, wherein said memory unit is a non-volatile memory.

11. A numerical control for machine tools or production machinery, comprising:

a main computer;

a follow-up device connected with said main computer via a data transmission network, wherein said follow-up device is addressable by said main computer via a logical address and a hardware address with information regarding a physical address of said follow-up device in said data transmission network is allocated to said logical address, wherein said main computer and said follow-up device are designed for carrying out a method for the start-up of a numerical control of machine tools or production machinery, the method comprising;

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; and

storing said logical address and said hardware address in a memory unit after said allocating information has been performed.

12. The numerical control in accordance with claim 11, wherein said data transmission system comprises serial point-to-point connections.
