EMULATOR FOR VISUAL DISPLAY OBJECT FILES AND METHOD OF OPERATION THEREOF

摘要

A system for, and method of, emulating, on a non-native computer (305), a native environment for a visual display object file for a real time process control system (100) and a real time process control system employing the emulator. The visual display object file contains a drawing command, an address pointer for communicating data with the real time process control system and a rule for interpreting data received from a touch-sensitive screen. The system includes: a display routine that causes the non-native computer (305) to control a non-native visual display (200) coupled thereto to display an image thereon as a function of the drawing command, an address mapping routine that communicates the data between the visual display object file and the real time process control system as a function of the address pointer and an input translation routine that translates data received into the non-native computer from a non-native pointing device (460) coupled thereto into data suitable for interpretation by the rule, the system thereby allowing the non-native computer to display the image, communicate the data with the real time process control system and interpret the data received from the non-native pointing device.
