Abstract

A method of identifying a node of an arrangement that includes a plurality of movable parts, the method including moving only one of a plurality of movable parts of an arrangement, detecting the moving of the one of the plurality of movable parts and distinguishing a node associated with the one of the plurality of movable parts based on the detecting.

Claims

1. A method of identifying a node of an arrangement that includes a plurality of movable parts, said method comprising:

moving only one of a plurality of movable parts of an arrangement;

detecting said moving of said one of said plurality of movable parts;

distinguishing a node associated with said one of said plurality of movable parts based on said detecting;

stopping said arrangement prior to said moving;

placing all nodes of said arrangement into a configurable state after said stopping and prior to said moving; and

naming a desired node identification for a particular axis of movement of said arrangement prior to said moving.

2. The method of claim 1, wherein said detecting is performed by a measuring device.

3. The method of claim 2, wherein said measuring device is programmed with a default node identification prior to said moving.

4. The method of claim 2, wherein said master unit saves configuration data of said measurement device which is associated with said identified node.

5. The method of claim 4, wherein said configuration data includes the serial number of said measurement device.

6. The method of claim 2, wherein said measurement device saves configuration data after being distinguished in a configurable state.

7. The method of claim 6, wherein said measurement device sends a confirmation message to said master unit indicating that the measurement device has received a new node identification.

8. The method of claim 1, wherein said arrangement is checked to insure its integrity prior to said moving.

9. The method of claim 1, further comprising having said measurement device enter said configurable state.

10. The method of claim 9, wherein only one node of said arrangement may be in said configurable state at any particular time.
