Abstract

An apparatus for electronically controlling a fiber processing machine includes at least one plug-in module group and at least one memory for receiving and storing data. A non-volatile memory is disposed physically apart from the plug-in module group whereby the data inputted in the memory are not lost upon switching off a power supply to the apparatus or upon replacing at least one plug-in module group and whereby upon resuming operation of the apparatus the data may be read and further processed.

Claims

1. An apparatus for electronically controlling a fiber processing machine, comprising:

a system bus;

at least one plug-in control module adapted to connect to the system bus; and

at least one memory connected to the system bus for receiving and storing data;

the memory being a non-volatile, electrically erasable and programmable memory, disposed physically apart from said at least one plug-in control module, such that when a supply voltage to the apparatus is shut down, the data are not lost and can be read further without additional equipment when the apparatus is started up again,

wherein the fiber processing machine comprises a spinning preparation machine, and said memory contains said data, which comprises an indication of elapsed operating hours of the fiber processing machine.

2. The apparatus as defined in claim 1, wherein said memory is a serial memory.

3. The apparatus as defined in claim 1, wherein said memory is a RAM including means for receiving a buffer voltage.

4. The apparatus as defined in claim 1, further comprising a circuit board;

said memory being positioned on said circuit board.

5. The apparatus as defined in claim 1, further comprising a central processing unit electrically connected to said memory.

6. An apparatus for electronically controlling a fiber processing machine, comprising:

a system bus;

a plurality of plug-in control modules adapted to connect to the system bus; and

at least one memory connected to the system bus for receiving and storing data;

the memory being a non-volatile, electrically erasable and programmable memory, disposed physically apart from any of said plurality of plug-in control modules, such that when a supply voltage to the apparatus is shut down, the data are not lost and can be read further without additional equipment when the apparatus is started up again,

wherein the fiber processing machine comprises a spinning preparation machine, and said memory contains said data, which comprises an indication of elapsed operating hours of the fiber processing machine.

7. A method of electronically controlling a fiber processing machine, including a system bus, plug-in control modules adapted to connect to the system bus, and at least one memory connected to the system bus for receiving and storing data, the method comprising:

applying the data to the memory, the memory being a non-volatile, electrically erasable and programmable memory, disposed physically apart from any of said plug-in control modules, such that when a supply voltage to the apparatus is shut down, the data are not lost and can be read further without additional equipment when the apparatus is started up again,

wherein the fiber processing machine comprises a spinning preparation machine, and said data comprises an indication of elapsed operating hours of the fiber processing machine.

8. The method as defined in claim 7, further comprising the step of serially exchanging data between said plug-in control module and said memory.

9. The method as defined in claim 7, wherein said step of applying data includes the step of applying data to said memory relating to one of a manufacture and a startup of the fiber processing machine.
