I have three identical AR1 boxes installed with the exact same build. I recently tried to view the data in a trend I have set up. It seems it can’t load the data for any of those screens. I always get the yellow exclamation graphic. The other 2 work just fine. Is there a part that stores the data on the AR1 that maybe be damaged?
You generally shouldn’t need to restart, but we have run into really hard to reproduce intermittent issues with OPC-UA connections. Is that what you’re using here?
If you do see your trend misbehaving again, it’d be interesting to see what happens if you hook up another gadget (just a Value or something) to the same tag. Does that second gadget get the same error?
On my project I have a total of 4 screens that display 1 trend per page and within each trend all 4 pens are being used. Three of the screens are exactly the same except the data displayed. However, on the forth screen, there is a trend and two set points. The values for the two set points were displayed, but the pens aren’t. So it seems to me it has something to do with where groov stores/retrieves the data. Each trend is only an hour worth of data and pulled every 5 seconds. We will keep an eye on it.
