I understand now that what you cannot do is update the PI value in the PI DA, which makes sense. But you can make the configuration change to have the attribute point to a new tag, which I think is what you were trying to do. Cheers, Keith

Why does the recommended high-availability solution differ with each PI program?

To get the PI Asset Framework, the PI Analysis Service, and the PI Notifications Service to be redundant, OSIsoft recommends using Windows Server Failover Clustering. To get the PI Data Archive to be redundant, we use PI Collectives. PI Connectors (Generation 1) use yet another type of failover. Why does the recommended high-availability… (Show more Show less)

Is it possible to correct historical data where the Interface was configured incorrectly. In this case someone forgot to swap modbus words so values that should be 0-10 percent are reading -129 Quintillion.

Modbus Data of Type 6 Function Code 3 was read from PLC to PI over past several years without swapwords. The initial setup crew did not validate the setup and we caught it this morning. Is there anything we can do to "salvage" the historical data?

Yes the data is 32 bit 4 byte floating point data and needs the words swapped to be meaningful. THank's I'll try manipulating a small sample with Excel and report progress another day.

How does PI Server timestamp events?

I'm having trouble seeing in the manual, how events are timestamped in the database. Is events timestamped in UTC +0 time and then presented in local server time? Or is events timestamped in local server time?

If you have interfaces that are buffering data, then the buffered data will be sent to the server when the connection is resumed; if you are not buffering data, there may be some data loss, but I think others can answer that better. If you have performance equations, then for the time the PI system is down, you may miss some calculations. If you…
