Apparatus and method for interactions with industrial equipment
Systems and approaches for interacting with industrial equipment are provided that include an interface having an input and an output, and a processor coupled to the interface. The processor is configured to link a uniform identification construct to a device and receive a request to access the uniform identification construct. The processor is further configured to translate the uniform identification construct into an internet protocol (IP) address and route the request to the device having the uniform identification construct according to the IP address via the output.
1 . A method, comprising:
linking, by a processor, a construct with a particular automation tag from among a plurality of automation tags of a Supervisory Control and Data Acquisition (SCADA) system or a plurality of automation tags stored in a data historian system, the construct comprising a semantic construct that identifies a specific attribute value hosted by the automation tag, and the automation tag corresponding to at least one of an attribute or a plurality of attributes within a device, or a property within an object the value of which is used in the SCADA system to perform control;
receiving a request from an application to access the automation tag by using the construct;
translating, by the processor, the construct into an internet protocol (IP) address;
responding at the direction of the processor to the request by routing the value of the specific attribute hosted by the automation tag to the application;
using a first digital signature to authenticate the request; and
using a second digital signature to authenticate a change or manipulation to an output of the request.
2 . The method of claim 1 , wherein the IP address is associated with a particular I/O point, and wherein the I/O point is associated with a set point and the set point is changeable.
3 . The method of claim 1 , wherein the particular automation tag is one of a plurality of automation tags the data historian system associated with the industrial process.
4 . The method of claim 1 , wherein the IP address is associated with a particular I/O point.
5 . The method of claim 1 , wherein the particular automation tag is one of a plurality of automation tags of a SCADA system.
6 . An apparatus, comprising:
an interface having at least one input and an output; and
a processor coupled to the interface;
wherein the processor is configured to:
link a construct with a particular automation tag from among a plurality of automation tags of a Supervisory Control and Data Acquisition (SCADA) system or a data historian system,
receive a request via the input from an application to access the automation tag by using the construct,
translate the construct into an internet protocol (IP) address,
respond to the request by routing the automation tag to the application via the output;
using a first digital signature to authenticate the request; and
using a second digital signature to authenticate a change or manipulation to an output of the request.
7 . The apparatus of claim 6 , wherein the construct comprises at least one of an Internationalized Resource Identifier (IRI), a uniform resource identifier (URI), a uniform resource locator (URL), an IPV4 address, an IPV6 address, an IPV6 address associated with an IEEE 64 bit extended address, or a 16 bit address unique to a local Personal Area Network (PAN).
8 . The apparatus of claim 6 , wherein the automation tag corresponds to at least one of a device, an attribute or a plurality of attributes within a device, or a property within an object.
9 . The apparatus of claim 8 , wherein the device comprises at least one of a sensor, an actuator, or a controller.
10 . The apparatus of claim 6 , wherein the processor is further configured to request and receive permission to access the device.
11 . The apparatus of claim 6 , wherein the IP address is associated with particular I/O point, and wherein the I/O point is associated with a set point and the set point is changeable.
12 . The apparatus of claim 6 , wherein the application comprises at least one of a client-based application or a web-based server.
13 . The apparatus of claim 6 , wherein the particular automation tag is one of a plurality of automation tags in the data historian system associated with the industrial process.
14 . The apparatus of claim 6 , wherein the IP address is associated with the particular I/O point.
15 . The apparatus of claim 6 , wherein the particular automation tag is one of a plurality of automation tags of a SCADA system.
