Abstract

The invention relates to automatically commissioning of devices of a networked control system, particularly to automatically commissioning (auto-commissioning) of light sources of a lighting system, where a control of light sources on an individual and local basis is required. A basic idea of the invention is to route commissioning messages through a grid, particularly an approximately rectangular grid of devices in that each device is able to receive commissioning messages from and to transmit commissioning messages to directly neighbored devices in the grid via light. An embodiment of the invention relates to a method for automatically commissioning of devices (10, 12, 14, 16, 18) of a networked control system, which comprises several devices arranged in a grid (20), wherein each device is adapted for routing messages, which were received from directly neighbored devices in the grid, to directly neighbored devices in the grid via light, wherein the commissioning comprises the acts of

• • transmitting a commissioning message (S10), which comprises a hops counter, by a first device (10) to a second device (12), which is neighbored to the first device in a predetermined direction (22) in the grid,
  • receiving the commissioning message (S12) from the first device by the second device,
  • updating the hops counter (S14) by the second device and a location counter of the second device and
  • transmitting the commissioning message (S16) with the updated hops counter to one or more third devices.

Claims

1. A method for automatically commissioning of devices of a networked control system, which comprises several devices arranged in a grid wherein each device is configured for routing messages between directly neighbored devices in the grid via light, method comprising

transmitting a commissioning message, which comprises a hops counter, by a first device to a second device, which is neighbored to the first device in a predetermined direction in the grid,

receiving the commissioning message from the first device by the second device,

updating the hops counter by the second device and a location counter of the second device and

transmitting the commissioning message with the updated hops counter to one or more third devices.

2. The method of claim 1, wherein

the act of updating of the hops counter by the second device comprises incrementing the hops counter by one and

the act of updating the location counter of the second device comprises setting the location counter to the maximum of the updated hops counter and the actual location counter.

3. The method of claim 2, wherein the act of updating of the hops counter by the second device further comprises

comparing the hops counter of the received commissioning message with the actual location counter of the second device and

incrementing the hops counter by one only the comparison results in that the hops counter is larger than or equal to the actual location counter of the second device.

4. The method of claim 3, wherein the act of updating of the hops counter by the second device further comprises rejecting the received commissioning message if the comparison results in that the hops counter is smaller than the actual location counter of the second device.

5. The method of claim 1, wherein the transmitting the commissioning message with the updated hops counter to one or more third devices comprises transmitting the commissioning message with the updated hops counter to

a third device, which is neighbored to the second device in the predetermined direction in the grid, or to

third devices, which are neighbored to the second device in the predetermined direction in the grid and in two further different directions, each being different from the predetermined direction.

6. The method of claim 5, wherein a third device, which is neighbored to the second device in a direction different from the predetermined direction, transmits a commissioning message in the predetermined direction in the grid.

7. The method of claim 5, wherein a third device, which is neighbored to the second device in a direction different from the predetermined direction, transmits a commissioning message in the predetermined direction in the grid and in the two further different directions, each being different from the predetermined direction.

8. The method of claim 1, wherein several commissioning message are routed in parallel through the grid in one or more predetermined directions.

9-11. -11. (canceled)

12. A system for automatically commissioning of devices of a networked control system, which comprises several devices arranged in a grid, wherein each device is adapted for routing messages, which were received from directly neighbored devices in the grid, to directly neighbored devices in the grid via light, wherein the system is configured to commission the devices by performing the acts of

transmitting a commissioning message, which comprises a hops counter, by a first device to a second device, which is neighbored to the first device in a predetermined direction in the grid,

receiving the commissioning message from the first device by the second device,

updating the hops counter by the second device and a location counter of the second device and

transmitting the commissioning message with the updated hops counter to one or more third devices.

14. A device being adapted for application in a system of claim 12, particularly a luminary, and being further adapted to communicate directional light messages.

15. The device of claim 14, comprising at least one of the following features:

the device is a luminary and being adapted in that the light of the main light source of the luminary is used for communication by means of directional light messages;

the device comprises collimators and/or lenses being applied to a light source used for communicating directional light messages and/or to a light sensor used for receiving directional light messages from other devices;

the directional light messages are invisible to the human eye;

the devices is adapted to communicate directional light messages in four different directions;

the devices is adapted to communicate directional light messages in four different directions, wherein the different directions are separated by an angle of 90°

degree.
