I have a few screen shots to show this. The tag is not visible in the GUI in ignition. You can manually type it in, and it will work. As you can see O:2 doesn’t show up, but it will work. ![](https://us1.discourse-cdn.com/inductiveautomation/original/1X/11898fa0c258bd51a3f001ca69122db1a8ef961a.JPG) ![](https://us1.discourse-cdn.com/inductiveautomation/original/1X/fbd4057351db7181b9063c498d0612425a962e3f.JPG) ![](https://us1.discourse-cdn.com/inductiveautomation/original/1X/6ef79396e6c841141e7df2c66c901c7311b4ca6c.JPG) ---

Just updated our test server to 7.1.2 that did not fix it, just an FYI. ---

How many O: words are in the SLC? If there are only 2, we may be off by 1. I don’t think this is the cause, but try deleting the DustCollector71101.tags file and then refresh the browse. ---

This is data we must maintain for 5 years. I don’t like the word delete… LOL Are you saying delete it from the SQL Tags Browser then re-add it? If not I am not following you. Jim ---

He is talking about a browse-cache file maintained in the Ignition Gateway installation directory. For example, it should be under some path like this: [tt]C:\Program Files\Inductive Automation\Ignition\contexts\main[/tt] This is not a “data” file - deleting it is safe. It is just a cache that the drivers use so they don’t have to go and browse the PLC all the time. ---

Ok, We are running on Linux. I found the tags file in: /usr/local/bin/ignition/contexts/main/drivers I deleted it, refreshed the browse. It made a new file, but they still are not there. PS\> Was off on vacation Friday, that’s why the delay in getting back. ---

Well we have any more ideas?
