hi there

sure, that's possible!

use the functions from the "DataSocket" palette. Use the "DataSocket Open" function to open a connection once at start of the app, then the "DataSocket Write" function whenever you want to write data and the "DataSocket Close" function at the end of your app to close the connection. right click "Help" on the functions to learn more or search the examples for "DataSocket".

Hint: there's a llb "dataskt.llb" in the vi.lib. the VIs in this llb are not recommended for future use. use the DataSocket functions instead.

I tried with the Socket connection but i always get the same error
Message "Access mode not supported for operation"


Any suggestions

your code is correct. it should work. check the opc server security settings of the item you want to write to. opc items can be set to "read only". there should be some kind of configuration application shipped with your opc server.
