Got a Edge gateway, and logging some sensor data on-change, or every 2 minutes if no change.So would expect data on all tags at all times.
For one of the sensors(not all, strangely enough), it suddenly seems to stop pulling data points into the powerchart.
I tried adding the same data to a Timeseries chart, and then all the data show as expected.
Looging at the picture attached below, I added a timeseries(red) chart on top of the powerchart, and they are both set up showing the same tag. As you can see, the data match up untill a certain point where the powerchart just cuts off.
Also notice that the "current value" of the pen is not showing. What could be the cause of this? I added the pen via the built in tagbrowser.
Other tags instances of the same UDT works without any issue. The tag instance is not having any issue and is showing data as normal.(Around 100 atm).
Any input on what might cause this issue?
If the tag's History | Deadband Style is not specifically set to Discrete you might see this problem as there won't be an entry in Historian until the value goes outside the analog deadband.
The tags deadband style is set to auto, but then I would expect that the value changes from where it changes from beeing to around 0 to around 100 would be shown?
And my concern is also why the current value is not showing under "Pen - Current value"? This should show no matter how the tag is set up to be logged?
I will try setting the deadband style to analog(it's a float).
Read the docs again.
Auto
The setting will automatically pick either Analog or Discrete, based on the data type of the tag.
- If the data type of the tag is set to a float or double, then Auto will use the Analog Style.
- If the data type of the tag is any other type, then the Discrete style will be used.
If you've set Auto on a float then it's already using Analog. I think you need to specify Discrete.
Ah, sorry, my bad.
I did try to set it to discrete half an hour ago now, but still no new data shows up on this tag. Only seems to be an issue with this tag, remaining tags looks to be working fine.
Inserting another tag into the powerchart shows all data as normal, as well as current value.
