Abstract

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.

Claims

1. An apparatus comprising:

a memory;

at least one processor, communicatively coupled to the memory, configured to facilitate execution of computer-executable components, the computer-executable components comprising;

a data structure comprising a data field and a corresponding name field; and

an updating component configured to read, from a machine readable representation of an automation device, information comprising an identity, a data type, and a data size of a data element that the automation device has available for exchange with a controller, to create a hierarchical tag representing the data element based on the information, to dynamically populate the name field with the hierarchical tag, and to communicatively map the data field of the controller to the data element of the automation device based on the information,

wherein the hierarchical tag comprises a device name that represents a name of the automation device and an element name that represents the data element of the automation device.

2. The apparatus of claim 1, wherein the at least one machine-readable representation is at least one of a device type manager, an electronic data sheet, or a device profile.

3. The apparatus of claim 1, wherein the hierarchical tag is formatted as <

the device name>

.<

the element name>

.

4. The apparatus of claim 1, wherein the device name is selectable and the updating component is configured to populate the element name to correspond to the data element represented by the hierarchical tag.

5. The apparatus of claim 1, wherein the updating component is further configured to populate the device name and the element name.

6. The apparatus of claim 1, wherein the information further comprises at least one of a position of the data element within an I/O block used to exchange information between the controller and the automation device or an offset of the data element within the I/O block, and the updating component is configured to communicatively map the data field to a segment of the I/O block identified by the position or the offset.

7. The apparatus of claim 1, wherein the data structure includes a store for current configuration information of the automation device, and the updating component is further configured to retrieve the current configuration information from the data structure and send the current configuration information to the automation device.

8. The apparatus of claim 7, wherein the update component is further configured to retrieve the current configuration information from the automation device and store the current configuration information in the data structure.

9. The apparatus of claim 1, wherein the updating component is further configured to determine a maximum message size supported by the automation device, to employ a fragmentation protocol to fragment the current configuration information into messages having respective sizes less than or equal to the maximum message size, and to transmit the messages to the automation device.

10. A computer-implemented method for automatically creating a data structure in a controller of an industrial control system, the method comprising:

receiving information from at least one machine-readable representation of an automation device, the information specifying an identity, a data type, and a data size of an input or output data element available within the automation device for exchange with the controller;

creating, within the controller, a data structure for mapping the input or output data element of the automation device to a data field in the data structure;

creating a hierarchical tag representing the input or output data element based on the information, the hierarchical tag including a device name representing a name of the automation device and an element name representing the input or output data element;

labeling the data field with the hierarchical tag; and

mapping the data field of the controller to the input or output data element of the automation device.

11. The method of claim 10, wherein the receiving the information from the at least one machine-readable representation comprises receiving the information from at least one of a device type manager, an electronic data sheet, or a device profile.

12. The method of claim 10, further comprising:

retrieving current configuration information from the automation device; and

storing the current configuration information in the data structure.

13. The method of claim 12, further comprising:

retrieving the current configuration information from the data structure;

determining a message size that does not exceed a maximum message size supported by the automation device;

fragmenting the current configuration information into a plurality of messages having respective sizes equal to or less than the message size; and

sending the plurality of messages to the automation device.

14. The method of claim 10, wherein the receiving the information includes receiving information specifying at least one of a position of the data element within an I/O block used to exchange information between the controller and the automation device or an offset of the data element within the I/O block, and the mapping includes mapping the data field to a portion of the I/O block corresponding to the position or the offset.

15. A non-transitory computer-readable medium having stored thereon computer-executable instructions that, in response to execution, cause a computing device to perform operations, including:

receiving a machine-readable representation of an automation device, the machine-readable representation comprising information defining an identity, a data type, and a data size of a data element of the automation device available for exchange with a controller;

creating, in response to the receiving, a data structure in the controller for mapping the data element to a data field of the data structure based on the information;

labeling the data field with a hierarchical tag comprising a device name that represents a name of the automation device and an element name that represents the data element of the automation device; and

mapping the data field to the data element.

16. The non-transitory computer-readable medium of claim 15, wherein the receiving the machine-readable representation comprises receiving at least one of a device type manager, an electronic data sheet, or a device profile.

17. The non-transitory computer-readable medium of claim 15, the operations further including:

retrieving a current configuration of the automation device; and

storing the current configuration in the data structure.

18. The non-transitory computer-readable medium of claim 15, the operations further comprising:
