I have a problem with certain tags failing to historize. These tags appear to have been sent to sqth_te (so they have a tagpath and tag_id), but do not appear in any of the partitioned historical tables. History is turned on in the UDT, and it looks like it propagated down to the instances, but i’m not convinced that the UDT instances’ tags are actually historizing even though their values are changing. This doesn’t happen for all tags/udts, but I am unsure as to why this is.
The error I am getting is this:
No historical tag information could be found for any of the specified paths. Check that paths are correct. Paths: [devices/rod pumps/32h/interface/sts/todayruntime, devices/rod pumps/32h/interface/sts/inferredprod, devices/rod pumps/32h/interface/sts/todaycycles]
Most of the easy chart bindings that we’re using have cell update binding, but again, I think history is simply not being recorded for several tags.
The tag history options we’re using are (mostly) default and identical in each UDT:
History Enabled = true
Storage Provider = “History”
Deadband Style = “Auto”
Deadband Mode = “Absolute”
Historical Deadband = “0.01”
Sample Mode = “On Change”
Min Time Between Samples = 0
Min Time Units = “Seconds”
Max Time Between Samples = 0
Max Time Units = “Hours”
It looks like only ~3515 / 4520 tags are being historized, the rest are being ignored. Not sure if re-starting the tag does the trick (in fact, some of these UDTs were completely abolished and re-created). All of the tag groups are the same.
Any ideas or advice?
