Embedding controllers and devices with data to facilitate up-to-date control and configuration information
An industrial automation system comprising a processor with an updating component coupled to automation devices via a network. The updating component reads control information from machine readable representations of the devices and populates a data structure with the control information. The updating component also updates configuration information of a device from data stored in a file object and/or the data structure, further allowing this transfer to be fragmented into a plurality of messages if the configuration information exceeds a threshold. As well, a vendor deployment methodology is provided that embeds devices and firmware for devices with a Device Type Manager (DTM) prior to deployment and can optionally allow post deployment updates to the DTM.
1. A system for creation of tags on an industrial controller, comprising:
a memory; and
at least one processor, communicatively coupled to the memory, configured to facilitate execution of computer-executable components, the computer-executable components comprising:
an updating component configured to:
read, from an industrial device, information about a data element available on the industrial device for data exchange with the system, wherein the information identifies an identity of the data element, a size of the data element, and a position of the data element within an I/O block,
populate a name field of a data structure within the industrial controller with a hierarchical tag created based on the information, and
communicatively map a data field of the data structure to the data element of the industrial device based on the information.
2. The system of claim 1 , wherein the updating component resides on the industrial controller.
3. The system of claim 1 , wherein the hierarchical tag comprises a device name that represents a name of the industrial device and an element name that represents the data element of the industrial device.
4. The system of claim 1 , wherein the information comprises at least one of a device type manager file or an electronic data sheet file that resides on the industrial device.
5. The system of claim 1 , wherein the updating component is further configured to identify the industrial device from which to read the information based on a profile of the industrial device maintained in a scanlist on the industrial controller.
6. The system of claim 1 , wherein the data structure is configured to store configuration information for the industrial device.
7. The system of claim 6 , wherein the updating component is further configured to retrieve the configuration information from the data structure and send the configuration information to the industrial device in response to a determination that a first configuration consistency value stored on the industrial device does not match a second configuration consistency value maintained on the industrial controller.
8. The system of claim 7 , wherein the updating component is further configured to fragment the configuration information into messages having respective sizes that are equal to or less than a maximum message size supported by the industrial device.
9. The system of claim 6 , wherein the updating component is further configured to read the configuration information from the industrial device and store the configuration information in the data structure.
10. The system of claim 1 , wherein the updating component is further configured to communicatively map the data field to a segment of the I/O block identified by the position.
11. A method for generating industrial controller tags, comprising:
reading, by an industrial controller comprising a processor, information from an industrial device describing a data element available on the industrial device for data exchange with the industrial controller, wherein the information defines an identity of the data element, a size of the data element, and a position of the data element within an I/O block;
populating a name field of a data structure in the industrial controller with a hierarchical tag created based on the information; and
communicatively mapping a data field of the data structure to the data element of the industrial device based on the information.
12. The method of claim 11 , further comprising creating the hierarchical tag based on the information, wherein the hierarchical tag comprises at least a device name of the industrial device and an element name corresponding to the data element.
13. The method of claim 11 , wherein the reading comprises determining the industrial device from which to read the information based on a profile of the industrial device stored on the industrial controller.
14. The method of claim 11 , further comprising:
reading, from the industrial device by the industrial controller, configuration information for the industrial device, and
storing the configuration information in the data structure.
15. The method of claim 14 , further comprising:
retrieving, by the industrial controller, the configuration information from the data structure; and
sending the configuration information to the industrial device or another industrial device.
16. The method of claim 15 , wherein the retrieving comprises retrieving the configuration information in response to a determination that a first configuration consistency value stored on the industrial device does not match a second configuration consistency value maintained on the industrial controller.
17. The method of claim 15 , wherein the sending the configuration information comprises:
determining a maximum message size supported by the industrial device; and
fragmenting the configuration information into messages having respective sizes that are equal to or less than the maximum message size.
18. A computer-readable storage medium having stored thereon computer-executable instructions that, in response to execution, cause an industrial controller to perform operations, the operations comprising:
reading a file from an industrial device, wherein the file contains information about a data element available for data exchange on the industrial device, and the information specifies an identity of the data element, a size of the data element, and a position of the data element within an I/O block;
creating a hierarchical tag based on the information and writing the hierarchical tag to a name field of a data structure within the industrial controller; and
communicatively mapping a data field of the data structure to the data element of the industrial device based on the information.
19. The computer-readable storage medium of claim 18 , wherein the hierarchical tag comprises at least a device name of the industrial device and an element name corresponding to the data element.
20. The computer-readable storage medium of claim 18 , wherein the operations further comprise:
reading, from the industrial device, configuration information for the industrial device, and
storing the configuration information in the data structure.
