I have a problem: In our existing setup, we used Siemens PLC connected to our local WinCC SCADA (same setup with other facilities we have). Now, Ignition SCADA was installed as our Central SCADA where all data from the different facilities are gathered. The problem is the data gathered from our local WinCC SCADA and Ignition SCADA are different (may be due to transmission latency and server time).

My question: Is there a way that these data from the SCADAs will be synched- meaning apple-to-apple data reporting?

We cannot use the data coming from the Central SCADA as our analytics basis since there is data discrepancy.

Thanks
