Embodiment Construction

[0025] Such as figure 1 As shown, an exemplary process control system 10 in which a digital video recording of a user display may be generated may include a process controller 12 connected to one or more host workstations or computers 13 which may be, for example, any type of personal computer or workstation , and also connected to field devices 15-22 through input / output (I / O) cards 16 and 28, each workstation or computer 13 has a display screen 14. A plurality of workstations or computers 13 can be interconnected via a network 9, such as figure 1shown. Controller 12, which may be, for example, a DeltaV™ controller sold by Fisher-Rosemount Systems, Inc., is communicatively connected to host computer 13 by, for example, an Ethernet connection, and also uses any desired hardware and software associated with, for example, standard 4-20ma equipment and and / or any intelligent communication protocol, such as a Fieldbus protocol, to communicatively connect to the field devices 15-...

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.

Description

technical field [0001] The present invention relates generally to process control systems, and more particularly to techniques and apparatus for digitally recording video output displayed on a user display in a process control system. Background technique [0002] Process control systems such as those used in chemical, petroleum, or other processes generally include a centralized type process controller. Field devices such as valves, valve positioners, switches, and transmitters (eg, temperature, pressure, and flow sensors) may perform in-process functions such as opening or closing valves and measuring process parameters. Process controllers receive signals indicative of process measurements made by field devices and / or other information pertaining to the field devices, use this information to implement control routines, and then generate control signals that are sent over the bus to the field devices to control the operation of the process . Generally makes information ...
