From 2015 until 6/18/2018, we've been able to use this application to write to PI tags with no issues. Our site was purchased by another company and servers were replaced. Since then, we've not been able to write to PI tags locally. However, in corporate they are not having this issue. The servers are on site locally and I have PIadmin rights. When I check Archive Editor in SMT, I see that it is not updated. The PiPutVal spreadsheet example (piexam32.xls) also has the same results. The example and the local spreadsheet return the response of "No events found" on the read back. PISDK message logs show nothing relating to this issue.
