Specify OPC Server on COPC32 ‘& lsquo; s residential property web page.

Along with OPC tags.

In Timer2’& rsquo; s code, getting OPC information right into global variable v( 0) to v( 2) (see downloaded and install instance code, will certainly see worldwide variable stated). And additionally reveal data on labels.

Personal Below Timer2_Tick(sender As Things, e As EventArgs) Manages Timer2.Tick
For i = 0 To 2
v(i) = Axcopc1.GetVl(i)

Label1.Text = v( 0 ). ToString()
Label2.Text = v( 1 ). ToString()
Label3.Text = v( 2 ). ToString()
End Below

I have use shell to call SQLCMD.exe with SQL command to put OPC information in to MS SQL table.
