Tags are collecting bad
quality data: FactoryTalk Historian ME’s support of controllers with
version 18 firmware assumes that the user makes no online
changes to a tag’s external access attribute. If your controller
is running version 18 firmware and you change a tag’s
external access attribute to “none”, then the data collected by
that tag for FactoryTalk Historian ME will be bad quality. To
fix this issue, you must change the tag value to either “Read/
Write” or “Read only” and reboot the module. This will solve
the problem.
