<P>PROBLEM TO BE SOLVED: To provide a method, device and product for accessing process control data. <P>SOLUTION: The method, device and product for accessing the process control data includes a step for loading a client object, and a step for communicating with a real object configured so as to make a data access request communicate with a server from the client object. The real object communicates with the server about an inquiry on the basis of the data access request, and acquires the process control data from the server in response to the inquiry. Next, the process control data is mapped to a second data layout related to a client schema from a first data layout related to a server schema. The mapped process control data is then communicated with an application. <P>COPYRIGHT: (C)2012,JPO&INPIT |
