Is there any way to import past history from another system into Honeywell PHD? We have a bunch of history going back 5 or so years in a “database” for which we have an ODBC-type interface. Can we get this data into PHD?
If you only have a week or two worth of history recovery that needs to be done up until the current time then setting up an OPC HDA RDI would work. Otherwise there is a command line tool for PHD called PHDImport. PHDImport pulls in data from a .dat file that is really a tab delimitted file with one data point per line. You will need an example file to get the format just right and if there is a large amount of data that needs to be imported you may need to implement a custom solution to export from another historian or a database.
The good thing is that the PHDImport command line tool imports the files very quickly and Process Wise has extensive experience with custom solutions solving this exact issue.
