Process control system using standard protocol control of standard devices and nonstandard devices
摘要
A process controller implements and executes a standard set of function blocks or control functions defined by a standard protocol so that standard-type control is achieved with respect to non-standard-type devices. The process controller enables standard devices to implement the standard set of function blocks and control functions. The process controller implements an overall strategy as if all connected devices are standard devices by usage of a Fieldbus function block as a fundamental building block for control structures. These function blocks are defined to create control structures for all types of devices.
