Apparatus and methods to access information associated with a process control system
First Claim
1. An apparatus to access information associated with a process control system, the apparatus comprising:
- a processor system; and
a memory communicatively coupled to the processor system, the memory including stored instructions that enable the processor system to;
assign a first user-defined parameter name to a first data source operating according to a first access protocol;
store identifying information in connection with the first user-defined parameter name, the identifying information being indicative of a location at which data from the first data source can be obtained;
configure a first interface assigned to the first data source to enable a second interface assigned to a second data source to submit to the first interface a data request including the first user-defined parameter name, the data request being of a second access protocol different from the first access protocol, wherein the first and second interfaces are instances of a particular object class, wherein the second interface is to access the second data source in response to receiving a second data request including a second user-defined parameter name;
in response to the data request of the second access protocol, access the first data source using the first access protocol and the identifying information using the first interface to provide a data value from the first data source to the second interface;
generate a third data request having a third access protocol associated with a third data source, the third data request excluding identifying information defining a location of the third data source; and
receive data from the third data source based on the third request.

Abstract
Example apparatus and methods to access information associated with a process control system are disclosed. A disclosed example method involves receiving a first user-defined parameter name to reference a first datum value in a first data source. The first one of a plurality of data source interfaces is enabled to access the first datum value in the first data source. The example method also involves enabling referencing the first datum value in the first data source based on the first user-defined parameter name. In addition, data source interface software is then generated to access the first datum value in the first data source in response to receiving a first data access request including the first user-defined parameter name.

12. A tangible machine accessible medium having instructions stored thereon that, when executed, cause a machine to at least:
assign a first user-defined parameter name to a first data source operating according to a first access protocol; store identifying information in connection with the first user-defined parameter name, the identifying information being indicative of a location at which data from the first data source can be obtained; configure a first interface assigned to the first data source to enable a second interface assigned to a second data source to submit to the first interface a data request including the first user-defined parameter name, the data request being of a second access protocol different from the first access protocol, wherein the first and second interfaces are instances of a particular object class, and wherein the second interface is to access the second data source in response to receiving a second data request including a second user-defined parameter name; in response to the data request of the second access protocol, access the first data source using the first access protocol and the identifying information using the first interface to provide a data value from the first data source to the second interface; generate a third data request having a third access protocol associated with a third data source, the third data request excluding identifying information defining a location of the third data source; and receive data from the third data source based on the third request. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method to access information associated with a process control system, the method comprising:
-
assigning, using a processor, a first user-defined parameter name to a first data source operating according to a first access protocol; storing identifying information in connection with the first user-defined parameter name, the identifying information being indicative of a location at which data from the first data source can be obtained; configuring, via the processor, a first interface assigned to the first data source to enable a second interface assigned to a second data source to submit to the first interface a data request including the first user-defined parameter name, the data request being of a second access protocol different from the first access protocol, wherein the first and second interfaces are instances of a particular object class, and wherein the second interface is to access the second data source in response to receiving a second data request including a second user-defined parameter name; in response to the data request of the second access protocol, accessing the first data source using the first access protocol and the identifying information using the first interface to provide a data value from the first data source to the second interface; generating a third data request having a third access protocol associated with a third data source, the third data request excluding identifying information defining a location of the third data source; and receiving data from the third data source based on the third request. - View Dependent Claims (24)
