.lpd file programatically

[anivij]

dear sir,

i am using labview 7.0 with DSC module. I have connected my modbus protocol based instrument with dsc module. Now presently i am creating .lpd file as per my instrument's memory configuration and after that making .scf file for the same. Using this setting my instrument is properly working properly with DSC module.

Now my requirent is, i want to make this .lpd and .scf file programatically. Is it possible if YES give me idea for that.

thanking you

yours

anivij,

Unfortunately you are not able to programmatically create the .lpd file.  This needs to be created in the OPC environment.  Please see this article for more information.

Also, the same goes for the .scf, this too is unable to be created programmatically.

Dear sir,

thanks a lot. Now my application is i want to connect my instrument with DSC module on serial bus. We are getting different tags on different memory location of instrument. These different tags we have now assigned in .lpd file. Similar way we are having many instrument with different address scheme. So i wnt such a type option such the if i give memory location for perticular tag the tag engine will access that tag without opening industrial automation opc server.

please help me for this

Falgandha,

You will still need to run IA OPC server.  It is the bridge between the devices and LabVIEW.  It is necessary that it runs.

anivij,

The way one would go about obtaining information from your array all depends on how your array has the dates and data stored.  I am assuming your array is a 2D array?  What have you done so far to work through your array?

Could you provide your code and where you are running into troubles?  Additionally, how are you obtaining this array?  Are you reading from a file?

Also, it would be best to keep individual questions on separate forum threads, as this question is not at all related to the original question in this thread.
