Tags dispear and "Error" shows in the Tag Browser of projects

General Discussion
1

I have created some OPC tags and memory tags for a couple of months. The tags had been running fine before a day ago. The tags disappeared and an error showing in the tag browser of the project. Great concern about this as we might lose the control of the machine if it happened when the project is implemented for production. Any comment regarding to this error and how to recover/prevent? Thanks.

Welcome to the forum!
You will have better luck getting help if you include some pertinent info like what version of ignition you are using, some detail on your missing tags, the error message, if there were any recent changes made etc…

The Version of ignition: 8.1.7 (b2021060314)
We lost all the tags in the tag provider
no error information available

Have a look in the wrapper log for errors

sorry but where can we find the wrapper log?

Status page of the gateway webpage, click on logs under Diagnostics

The wrapper log file itself is under your ignition install directory + /logs/wrapper.*
It’s basically the same as what’s on the webpage log page. Can you post your wrapper log file?

12

I can not upload the file, is there other way to send the file?

I’m guessing it has something to do with these, @PGriffith, over to you :grimacing::
