Abstract: A system for, and method of, generating a control drawing representing interconnections among elements of a real-time process control system and a plant controlled thereby. The system includes: (1) a memory that receives and stores textual input data representing explicit point connections among the elements, control language scripts containing implicit point connections among the elements and data regarding a starting element and (2) a processor, coupled to the memory, that analyzes the explicit and implicit point connections relative to the starting element and automatically constructs the control drawing as a function of the starting element, the system thereby generating the control drawing representing the interconnections.

Abstract: A testing system for, and method of, simulating signal flow through a logic block pattern of a real time process control system. The system includes: (1) a memory that contains a data base of input data associated with simulated sensors and a rule base containing control rules and constituting a logic block pattern and (2) a processor that operates in an arbitrary time base to apply the input data to the control rules to simulate signal flow through the logic block pattern and thereby produce simulated output data and real time control system responses thereby testing the logic block pattern, the memory and the processor being detached from the real time process control system to prevent use of resources thereof in connection with the logic block pattern testing.
