Has anyone developed an easy way to enter manual tag data?
We have a set of applications dedicated to that task, they fall under the umbrella of the PI Manual Logger: https://livelibrary.osisoft.com/LiveLibrary/content/en/manual-logger-v3/GUID-FA601C7B-05D0-4A0A-8FF8-0605E1DD728A
Jerome Lefebvre suggestion is good, but if you are looking to a more simple solution you could try DataLink's functions.
Documentation is on the PI Live Library: PI DataLink
