In-Vision is Rotork’s new, user-friendly supervisory control and data acquisition software package designed for use with Rotork’s Pakscan two-wire valve actuation control system. Developed from Pakvision package, In-Vision runs under Windows 9X, NT or W2000 to introduce many new visual features and operational benefits. With over 20,000 I/O points, each In-Vision is suitable for automated plants containing up to 480 Pakscan controlled valves. Even larger systems can be controlled by using multiple applications spread across several PCs. In-Vision enables a totally customised, full-colour visual display of the site to be used to monitor and operate the plant using information collected on the Pakscan two-wire control bus. Customisation options include the ability to include photographic images on the animated screen overviews and close-ups that display general plant conditions. Detailed examinations of chosen plant areas can be performed using enlargements featuring coloured animations to highlight alarms or areas requiring attention. To further facilitate plant operation, every In-Vision system incorporates multiple windows providing status and alarm information and showing the condition of every actuator and master station on the Pakscan system. Audible warnings and action confirmation dialogue boxes can be included to enhance safety where plant controls are critical.
