Is it possible to connect LABVIEW directly to a Siemens PLC using OPC server?

[GHS]

In my college we have simulated an automated mini assempling line with Labview and later with another program we connect to the PLCs. Is it possible to do it directly from Labview to the PLCs using OPC server if so how does it works and what is needed to do so.
Thank you very much.

Hello,

National Instruments has OPC Server software that is capable of communicating with a large number of PLCs, RTUs, and other industrial hardware. The software handles communication with the hardware and exposes every register or channel within the hardware as an OPC data item. These drivers were developed with 32-bit addressing for Windows 9x\NT\2000\ME\XP operating systems.

The DSC Module is the ideal tool for your distributed monitoring applications and features an OPC server. Use the configuration-based Tag Engine to read and write to these OPC data items.

See the following URL for specific information regarding which model Siemens PLCs are supported: http://www.ni.com/opc/opcservers.htm

Hope this helps.
