Abstract

The disclosure includes a method of automation technology for wireless transmission of at least a first information between an initiator and a plurality of receivers in a receiving mode, comprising: transmitting the first information by the initiator in a first communication pulse; receiving the first information by at least one receiver; transmitting an additional communication pulse containing the same first information as the first communication pulse, by at least one receiver that received the first communication pulse, and changing the at least one receiver into an acknowledgment mode; repeating the previous step, until all receivers are changed into the acknowledgment mode; activating at least one receiver, which is located in the acknowledgment mode; performing the at least one additional command contained in the received first information by the activated receiver; and changing the activated receiver into the receiving mode. The disclosure also includes a system suitable for performing the method of the invention.

First claim

The invention claimed is:

1. A method of automation technology for wireless transmission of at least a first information between an initiator and a plurality of receivers initially operating in a receiving mode, comprising:
transmitting a first communication pulse including the first information, the first information including a command for passing-on the first information and including at least one additional command, by the initiator;
receiving the first communication pulse by at least one receiver of the plurality of receivers;
transmitting an additional communication pulse including the first information, by the at least one receiver that received the first communication pulse;
changing the at least one receiver that received the first communication pulse from the receiving mode to an acknowledgment mode;
receiving the additional communication pulse by at least one receiver of the plurality of receivers operating in the receiving mode;
repeating the transmitting of the additional communication pulse, the changing to the acknowledgement mode, and the receiving of the additional communication pulse until all of the plurality of receivers are changed to the acknowledgment mode;
activating at least one receiver that is operating in the acknowledgment mode;
executing the at least one additional command contained in the first information, by the activated receiver; and
changing the at least one activated receiver to the receiving mode.

2. The method as claimed in claim 1 , wherein the receivers that received the first communication pulse or the additional communication pulse change for a defined time to the acknowledgment mode before changing back to the receiving mode.

3. The method as claimed in claim 1 , wherein a dedicated radio channel is used for transmitting the first communication pulse and the additional communication pulse.

4. The method as claimed in claim 1 , wherein the additional communication pulse further includes a count of earlier sent pass-ons.

5. The method as claimed in claim 4 , wherein the count of pass-ons is limited.

6. The method as claimed in claim 1 , wherein a transmission power of the communication pulses is limited.

7. The method as claimed in claim 1 , wherein the at least one receiver operating in the acknowledgment mode is activated by pressing a button on the at least one receiver.

8. The method as claimed in claim 1 , wherein the at least one additional command includes a request for providing and/or for transmitting process data of a receiver to the initiator.

9. The method as claimed in claim 1 , wherein the at least one additional command includes an invitation for integration into a wireless network and the receivers are either already integrated participants, which exclusively forward the first information or potential participants, which forward the first information and change into the acknowledgment mode.

10. The method as claimed in claim 9 , further comprising:
sending a report back from at least one potential participant to the initiator after the activating of the potential participant;
sending access parameters for the wireless network from the initiator to the potential participant; and
integrating the potential participant into the wireless network.

11. The method as claimed in claim 9 , further comprising:
the potential participant receiving a communication pulse and automatically sending identification data to the initiator without changing to the acknowledgment mode; and
the initiator comparing the identification data with a list and, in the case of agreement, automatically integrating the potential participant into the wireless network.

12. The method as claimed claim 1 , further comprising:
after receipt of the first information, exchanging additional information bidirectionally between the at least one receiver and the initiator, wherein the additional information is passed on via the plurality of receivers and the plurality of receivers remain in the receiving mode.

13. A system for wireless transmission of at least a first information comprising:
an initiator configured to
transmit a first communication pulse including the first information, the first information including a command for passing-on the first information and further including at least one additional command; and

a plurality of receivers, each receiver configured to:
receive the first communication pulse,
transmit an additional communication pulse including the first information,
change from a receiving mode to an acknowledgement mode after receiving the first information,
receive the additional communication pulse when in the receiving mode,
change from the acknowledgement mode to an activated mode upon a button press on the receiver,
execute the at least one additional command when in the activated mode, and
change from the activated mode to the receiving mode.

14. The system as claimed in claim 13 , wherein the initiator and the receivers are components of automation technology and include wireless communication units.

15. The system as claimed in claim 14 , wherein the initiator is a superordinated unit and the receivers are field devices.

16. The system as claimed in claim 14 , further comprising:
a wireless network, in the case of which the receivers are either already integrated participants or potential participants, wherein the wireless network is a wireless network of automation technology.
