Did you see this webpage?  http://zone.ni.com/devzone/cda/epd/p/id/4756

 

The zip file appears to have a version in LabVIEW 7.1.

Did you download and look in the ni_modbus_1_2.zip?

 

There was a directory of 7.1 version files in there.  You will be able to open those in 8.0.

 

PS.  You may want to use the spell checker.  The proper spelling for "cudnt" is "couldn't."

Ya..i was able to use 7.1 version and working fine.

 

Is there anyother specific requirements for working with modbus?

 

It was not because i dont knw the spelling of couldnt.I just made it shorten..And for communication it didnt make any bad effect as i could find the solution still.

 

But i never noticed the check spelling option here.Thank u for the info and feedback.

 

Thanks again...

What 'logger'  are you using?? Modbus is a master/slave communication protocol. The master requests to either read or write data from the slave. The data could be discrete bits or blocks of 16 bit register values. read the protocol manuals here. http://www.modbus.org/specs.php There are many examples of modbus communications in these forums.
