Dear Mikhail,
I know I should not use MSSQLCompact from SCADA-Server.The reason I do that is I need to deal with a problem that Once I Click on pass to SCADA-Server in ScadaAdmin application,the Modification in BaseDAT disappears and returns to a state which I did nothing about it,and I realized that BaseSDF rules,it will determine BaseDAT. Is there any approach to Solve this problem?
