Abstract

A method for loading program modules into programmable network devices of a network comprises loading an ID-generator into each network device for generating a unique identification code for the network devices. Next the program modules are loaded into the network devices based on the identification codes. Thus selective programming of network devices within a network is possible.

Claims

1. A method for loading a program module into one of a plurality of programmable network devices connected to a network comprising the steps of:

loading an ID-generator into at least one of the plurality of network devices, the ID-generator comprising a program module for generating a unique identification code for each of the plurality of network devices;

generating an unique identification code for at least one of the plurality of network devices by executing the ID-generator;

assigning the program module to an identification code, and

loading the program module into the one of the plurality of network devices having the identification code assigned to the program module.

2. The method of claim 1,

wherein the step of assigning the program module to an identification code further comprises determining the position of one of the plurality of network devices before assigning the program module to an identification code.

3. The method of claim 2,

wherein the step of determining the position of one of the plurality of network devices further comprises determining an environment of the network device.

4. The method of claim 2,

wherein the step of determining the position of one of the plurality of network devices further comprises generating an electrical signal at a connector of the network device and detecting a reaction to the electrical signal at a connector of the network device.

5. The method of claim 1,

wherein the step of generating a unique identification code further comprises generating a random number.

6. The method of claim 1,

wherein the step of generating a unique identification code further comprises counting clock cycles of a clock signal for a predetermined time period.

7. The method of claim 1,

wherein the step of generating a unique identification code further comprises determining whether the same identification code has been generated for two of the plurality of network devices, and executing in such case a conflict resolving routine.

8. The method of claim 7,

wherein the step of executing a conflict resolving routine further comprises re-executing the ID-generator.

9. The method of claim 1,

wherein the step of generating a unique identification code further comprises storing a unique identification code in a non-volatile memory of a network device.
