I’ve already used ModDBExport module,but the data is not imported into the database(postgresql) . Before that, I had been configured as a document .
DROP TABLE IF EXISTS cnldata;

— Create channel data table
CREATE TABLE cnldata (
datetime timestamp NOT NULL,
cnlnum integer NOT NULL,
val double precision NOT NULL,
stat integer NOT NULL,
PRIMARY KEY (datetime, cnlnum)
);

CREATE INDEX ON cnldata (cnlnum);

The above runs at postgres ,and The insert statement runs in current data in the ModDBExport attribute

How do I set the data to be received by the Scada-Server ?

1.Generate a file that name is KpPost.dll .The file depends on a Npgsql.dll
2.Use the SetCurData method to set the current value.
3.KpTestView class inherits the KpView class and then creat input channels.

I want export to postgresql database by using ModDbExport module,and it is success.
But the data is constantly exported to postgresql database .so I want to be able to control the export period,or other methods avoid continuous export. I’m not sure if I have a clear description .
