What is the Updation time in PI applications like datalink and Processbook. How can we configure the updation time of live data
PI DataLink doesn't grab live data. The most often that PI DataLink could grab data is every time the workbook calculates.
I haven't used PI ProcessBook, so I don't know how often it updates, but keep in mind that PI ProcessBook is deprecated in favour of PI Vision. The update rate in PI Vision is configurable and can be as often as every second.
If I remember correctly, PI ProcessBook default out-of-the-box refresh rate is 60 seconds.
The default refresh rate for PI ProcessBook is 5 seconds and this should be the same as in PI Vision.DataLink supports automatic calculation which normally sets the interval automatic. But this should also be configurable within the settings menu.
5 seconds interface for ProcessBook is indeed the standaard.
for Datalink, you are in control... but be careful (!!) .... if you have a large Datalink sheet with lots of data and calculations, give your system the time to execute it...
Setting Datalink auto update see below
To add to the automatic recalculation in PI Datalink, also note that the type of the functions used in PI Datalink also have an impact in refresh rates (Single value calls vs. Bulk calls).
