Check out the DSC add-on, or the OPC  add-on. There is an extensive list of PLC's that they allow you to communicate with.

There are also third-party OPC add-ons available. Check out with Google.

 

 

Good luck,

Check out the website for the basic communications modules.  You might have to read the Mitsubishi manual to find how the PLC works.  If there aren't pre-written comunication modules, you'll need to learn enough LabVIEW to write those.

Try the above link. I know it is a screen-full, but is a search result for Matrikon. They have a whole slew of OPC servers/clients you can try out. Personally, I would go with their OPC server for the Mitsubishi, and use Labview Datasockets. That would be the simplest with the lowest learning curve.

 

Otherwise, if you wish to use Modbus, you would have to get the commands/syntax from Mitsubishi; might be in their user manual, but I wouldn't lay bets on it. With the Matrikon stuff, the syntax is all built in.

 

Good luck which ever way you decide to go.

A cry for help is not enough. You need to be very specific about what you are having problems with.
