PI ACE point used as ACE input & output and manual entry

Hello everyone,


I have about 4000 tags that will have a manual input. This tag will be evaluted by PI ACE, and the calculation result will be stored in the same tag.


The calculation works fine. My only problem is that PI ACE has a buffer, which prevents me from writing new manual values to that tag. I get the error "Buffered point does not accept new events".


I know that, if I create separate tags to receive the manual values, it would work, but I would like to be more efficient not spending 4000 mores to receive values once in a while. I also have a IT constraint that prevent the users from enabling PI SDK buffer on client machines.


Does anyone have any idea on how to solve this problem without creating additional tags?
