摘要
A system for, and method of, providing encapsulated and performance-efficient data references in an object-oriented controller and a distributed, real time process control system employing the system or the method. In one embodiment, the system includes: (1) a client algorithm block that generates a request for an address to enable the client algorithm block to gain direct access to data stored at the address and (2) a supplier algorithm block, that receives and evaluates the request and: (2a) if the supplier algorithm block grants the request, communicates the address to the client algorithm block, allowing the client algorithm block to gain direct access to the data and (2b) if the supplier algorithm block denies the request, withholds the address, forcing the client algorithm block to gain indirect access to the data.
