I have 4 instances of the OPC DA interface running on my interface machine. 2 existing interfaces are working fine with buffering to the data archive but the 2 new ones I created, by basing them on the 1st running instance, are not using buffering and are trying to write data directly to the tags (and failing since the account they are running under is not the buffer service account and doesn't have access)
Why are they not going through pibufss? How can I diagnose and resolve this? What could cause it? All 4 instances are reading from the same local OPC server and writing to the same data archive.
Thanks in advance for any suggestions
