HMI display operation

I am planning on designing several overview screens for an operation at our plant.  If I plan on including 4 - 5 screens is there some way to have DeltaV automatically change the HMI graphics so the images don't get burned into the screen.   I would like to have them rotate on a 30 or 60 second cycle.

Thank you.

Dan

    Hi Dan,
    I dont have an exact answer for you I am afraid. The only thing that I can think of is to utilise the code which is used on PCSD faceplates to jump them from one screen to the next. If you take this code and add it to a DeltaV Operate scheduler you may be able to achieve this. Sorry I can't be more specific it is not an area of DeltaV I am active in.

    Kind regards

    Scott

    I realize that this is an old question but I thought I would respond. You could use a custom schedule in DeltaV which changes the picture . You could include a timer object in your graphics (a toolbar is a good location) that executes periodically and changes the display that is shown.
    Additionally, you could choose a technology for your overview screens themselves that resists burn in. Many televisions have a feature that moves the image by a few pixels to combat this or have a "whitewash" image that they can flash to clear the burn in.
