METHODS AND APPARATUS FOR ACCESSING PROCESS CONTROL DATA
First Claim
1. A method for accessing process control data, comprising:
- loading a client object;
communicating a data access request from the client object to a real object configured to communicate with a server;
communicating a query from the real object to the server based on the data access request;
obtaining process control data from the server in response to the query;
mapping the process control data from a first data layout associated with a server schema to a second data layout associated with a client schema; and
communicating the mapped process control data to an application.

Abstract
Methods, apparatus, and articles of manufacture for accessing process control data involve loading a client object and communicating a data access request from the client object to a real object configured to communicate with a server. The real object then communicates a query to the server based on the data access request and obtains process control data from the server in response to the query. The process control data is then mapped from a first data layout associated with a server schema to a second data layout associated with a client schema. The mapped process control data is then communicated to an application.

12. An apparatus for accessing process control data, comprising:
- a processor system; and
a memory communicatively coupled to the processor system, the memory including stored instructions that enable the processor system to;
load a client object;
communicate a data access request from the client object to a real object configured to communicate with a server;
communicate a query from the real object to the server based on the data access request;
obtain process control data from the server in response to the query;
map the process control data from a first data layout associated with a server schema to a second data layout associated with a client schema; and
communicate the mapped process control data to an application. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
