how to use modbus lib in labview 8.2

[powermon]

I try to use NI Modbus.llb (MB Serial Init.vi,...) to build my application.  My software is Labview 8.2 professional version.

I downloaded the llb from the link provided from previous messages found in  this forums.  The files were downloaded to my PC under

C:\Program Files\National Instruments\LabView 8.2\vi.lib\NI Modbus.llb.  These vi files cannot be selected and droped to VI's block diagram. 

Am I downloaded the right files?

Does LabView 8.2 support these files?

How to use them in LabView 8.2?

This link did not work.

I have created some applications using LV8.0 and the old Modbus library. We are now installing LV8.2 on another computer in our office, will these applications be editable in 8.2. Is it the same modbus library?

Hi Christian_nor,

The current version of the Modbus LabVIEW Library is only officially supported in LabVIEW 7.1, but can be manually installed in LabVIEW 8.0 and later.  The installer for the current version of the Modbus LabVIEW Library looks in the Windows registry for the presence of LabVIEW 7.1, and will not install if the LabVIEW 7.1 registry key is not found.

The installer at this link will automatically place the nimodbus.mnu and NI Modbus.llb in the appropriate folders in the LabVIEW 8.2 directory.  You should be able to edit the programs as normal in LabVIEW 8.2 once these files are installed in the LabVIEW 8.2 directory.

Let me know if you have any questions!
