Abstract

Implementations are described herein for commissioning a distributed control node (DCN) to a process automation network. In various implementations, one or more messages transmitted on the process automation network by the DCN announcing that the DCN has joined the process automation network may be detected. Based on the one or more messages, one or more operational technology (OT) capabilities of the DCN may be determined. Based on the one or more OT capabilities, the DCN may be commissioned to the process automation network, e.g., by configuring the DCN to cooperate with one or more other process automation nodes on the process automation network to implement an at least partially automated process.

First claim

What is claimed is:

1. A method for commissioning a distributed control node (DCN) having multiple input/output (I/O) channels to a process automation network, the method implemented using one or more processors and comprising:
detecting one or more messages transmitted by the DCN on the process automation network, wherein the one or more messages transmitted by the DCN on the process automation network announce that the DCN has joined the process automation network and convey operational technology (OT) capabilities of the DCN, including a count of the multiple I/O channels of the DCN and types of the multiple I/O channels;
determining, from content of the one or more messages transmitted by the DCN on the process automation network, the OT capabilities of the DCN; and
based on one or more of the OT capabilities, commissioning the DCN to the process automation network, wherein the commissioning includes:
matching one or more other process automation nodes on the process automation network to the DCN; and
configuring the DCN to cooperate with one or more of the matched other process automation nodes on the process automation network to implement a process control loop that includes operating at least one actuator of one or more of the matched other process automation nodes based on one or more sensor signals generated by one or more of the matched other process automation nodes.

2. The method of claim 1 , wherein the matching includes matching at least one actuator of the process automation network with the DCN based on a profile of the at least one actuator.

3. The method of claim 1 , wherein the matching includes matching at least one sensor of the process automation network with the DCN based on a profile of the at least one sensor.

4. The method of claim 1 , wherein the detecting includes receiving one or more of the messages as a multicast message.

5. The method of claim 1 , wherein the configuring includes causing configuration data to be installed on the DCN, wherein the configuration data facilitates cooperation between the DCN and the one or more other nodes on the process automation network to implement the process control loop.

6. The method of claim 5 , wherein the causing includes pushing the configuration data to the DCN over the process automation network.

7. The method of claim 1 , wherein the one or more OT capabilities of the added DCN further include one or more of:
a range limit associated with the DCN;
a preferred unit of measurement of the DCN;
an update frequency of the DCN;
one or more analog-to-digital conversion parameters of the DCN;
one or more signal conditioning parameters of the DCN; or
any combination thereof.

8. The method of claim 1 , further comprising verifying or authenticating the DCN based on data received over one or more computer networks from a vendor system associated with the DCN.

9. The method of claim 8 , wherein the verifying comprises cross- referencing identification information associated with the DCN with the data received from the vendor system.

10. A distributed control node (DCN) having multiple input/output (I/O) channels and comprising circuitry to:
transmit one or more messages on a process automation network, wherein the one or more messages transmitted by the DCN on the process automation network announce that the DCN has joined the process automation network and convey one or more operational technology (OT) capabilities of the DCN, wherein the OT capabilities include a count of the multiple I/O channels of the DCN and types of the multiple I/O channels;
receive configuration data from a configuration node over the process automation network, wherein the configuration data includes:
information technology (IT) configuration data that enables the DCN to engage in network communication with other nodes on the process automation network, and
OT configuration data that enables the DCN to operate one or more compatible actuators based on one or more sensor signals generated by one or more sensors on the process automation network to implement a process control loop, wherein the one or more compatible actuators are matched with the DCN based on one or more of the OT capabilities; and
in accordance with the configuration data, exchange data with one or more of compatible actuators or sensors to implement the process control loop.

11. The DCN of claim 10 , wherein the circuitry is to receive a software or firmware update from, or at the direction of, the configuration node.

12. The DCN of claim 10 , wherein the IT configuration data includes a security certificate to facilitate encrypted communication.

13. The DCN of claim 10 , wherein the IT configuration data includes time sensitive networking settings.

14. A system for commissioning a distributed control node (DCN) having multiple input/output (I/O) channels to a process automation network, the system comprising one or more processors that execute instructions stored in memory to:
detect one or more messages transmitted by the DCN on the process automation network, wherein the one or more messages transmitted by the DCN on the process automation network announce that the DCN has joined the process automation network and include;
operational technology (OT) capabilities of the DCN, including a count of the multiple I/O channels of the DCN and types of the multiple I/O channels;
determine, from content of the one or more messages transmitted by the DCN on the process automation network, the OT capabilities of the DCN; and
based on one or more of the OT capabilities, commission the DCN to the process automation network, wherein the instructions to commission comprise instructions to:
match one or more other process automation nodes on the process automation network to the DCN; and
configure the DCN to cooperate with one or more of the matched other nodes on the process automation network to implement a process control loop that includes operating at least one actuator of one or more of the matched other process automation nodes based on one or more sensor signals generated by one or more of the matched other process automation nodes.

15. The system of claim 14 , comprising instructions to match at least one actuator of the process automation network with the DCN based on a profile of the at least one actuator.

16. The system of claim 14 , comprising instructions to match at least one sensor of the process automation network with the DCN based on a profile of the at least one sensor.

17. The system of claim 14 , wherein one or more of the messages is detected as a multicast message.

18. The system of claim 14 , wherein the configuring includes causing configuration data to be installed on the DCN, wherein the configuration data facilitates cooperation between the DCN and the one or more other nodes on the process automation network to implement the process control loop.
