Abstract:
A process control system user display provides a display image containing control system information. The system may include a digital recording module including an image capture module for making a real-time digital recording of at least a portion of the display image, the image capture module buffering a terminal portion of the real-time digital recording. A storage module may store at least a portion of the real-time digital recording. A real-time digital recording may contain at least a portion of the display image, wherein, at any particular time, the real-time digital recording includes information from the control system for a predetermined duration proximate the particular time, and at least a portion of the real-time digital recording may be stored. A desired portion of the digital recording may be played back, optionally with process control system event and/or continuous history.
