Labview and PLC

[Trupti]

Hi,

  I have a project where I have to communicate between Labview and Siemens PLC. 

Can anybody point me to correct direction (like reading material, Examples etc.) about how to do it?

thanks

The most obvious option is to use OPC to communicate between LabVIEW and the Siemens PLC.  With just LabVIEW, you can use DataSocket for OPC, but if you have 100+ tags (IO points), you will be better off using the built-in OPC Client in LabVIEW-DSC. 

Read up on OPC and LabVIEW-DSC for starters.

Hi,

If this is a Siemens C7-300 or S7-200 series PLC, you can read or write data (data, flags, inputs, outputs) using DLL calls to Prodave MPI product from Siemens. I have a couple of wrapper VI for some basic functions, but you need to purchase Prodave MPI to use them.
