LabVIEW can also communicate over Modbus (Ethernet or serial) via the Modbus Library (free) or the DSC Module (easier).

Easier, if not bought.

Hiii Micheal and all,

  OOps!!! unknowingly in pressed solution sloved......is ther any option to do undo for that....anyways the issue is closer to the solution and michael in that diagram everything was grouped its wrong and giving confusion for evebody, you can see this new attached one, hope its understandable. We planning to use prolink PDPM profibus to modbus tcp/ip for linking to our network....now i want to know will ther be any technical issues in reading this in labview.

Hi Pravin

I don't know if you can unset the 'solved' status; maybe a moderator reading this can fix that for you.

I couldn't read your revised network diagram, it seemed to be a zip file full of xml docs. Mayb you can stick to doc format, since many people don't have office 2007.

can i control schneider plc with a labview interface via rj45 ?

[RavensFan]

Yes.

This is a nearly 7 year old thread about a Siemens PLC.

If you have specific problems or questions about your Schneider PLC, then I recommend creating a new thread, providing details, and asking specific questions.

thanks for your reply! so i have to do an interface in labview to control the plc !and this is my first experience ! so i don't know how can i ensure the communication and the transmission of data between plc and labview.I have to know the steps to do to ensure communication between my labview interface and plc. 🙂

Hi bmwassim, 

Like RavensFan said you will probably get a better response from the community as a whole by creating a new post, but if you are new to communicating between PLCs and LabVIEW take a look at this tutorial:

Hope this gives you a godd starting point!
