Re: v24 Axiom not releasing View/Historian Resources
Hi@Shawn Rieger , Thanks for reporting this. The bug that was fixed in 24.2 was concerning Automated Reports as that was the main culprit. There are still scenarios which can cause these messages to…

Re: error: 0x40020400
Hi@shook , Maybe the Historian is not able to release the tag writer handle. You could also try stopping the Historian service as well to see if that alleviates it.

Re: SAF Import Fails with Datetime Conversion
Hi@zach. hoskin , I think you just need to shift your column offsets by 1. The column offset count starts at 0, not 1. Let me know if that works.

Re: Close Notification for SaF
Hi @Damon Vinciguerra , There is a follow-up email, but I'm not sure why it would not have been sent in your circumstance. I got a few of these messages over the weekend. 2025/05/19 08:11:53.…

Re: Duplicate the chart export functionality with Web Read API
Hi@erice , I think this is occurring because there is no data yet for those timestamps. The Historian does a time-extension for tags that are static, but this only occurs about once a minute.…

Re: OPC DA Collector - Data Transform - NoOutput

Re: OPC DA Collector - Data Transform - NoOutput
@Alejandro SantiagoI'm not sure it would be any different as 'NoData' quality values are treated virtually the same as Bad quality values.
