I have two custom values each with dataset [1x71] from historian bindings on a perspective page.
For some reason, since the last two resets, one of them has been toggling between dataset [1x71] and dataset[0x0].
I am using Ignition 8.1.
Is there a known cause or solution to this?
I think you are going to need to include a lot more information than that
On all my pages with more than one historian binding, I have this issue on some of them.
No property changes on any of them? Can you show the binding that is being problematic? And if its referencing a tag, show that tag’s configuration as well?
[0x0] would suggest to me that the data source is intermittently returning no results.
I believe from your other threads that you can’t share detail due to NDA etc. Your fastest progression may be a ticket with support.
It is also possible that your start date and end date are changing separately, briefly yielding a backward interval (which will have no results). Add some logging to your bindings.
How do you add logging to a historian binding?
point count, 1 count
time range 1, minute
polling 30 seconds
direct, 71 tags, aggregate default
options enabled, dataset
I will look at the other pages to see if there is a patter with the configuration.
On the page with the two historian bindings though, they are both configured the same.
One was populating consistently, and the other was not for a few hours.
Ignition 8.1.0, updating in a month or two though.
If you have a transform script, do it there. Or perhaps use propertyChange actions on the properties you are referencing in that binding.
