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?
