OPC server 2009 doesn't support for Siemens S7-1200 PLC

[Vij@y]

Dear all,

I am Using NI OPC server 2009 to communicate with Siemens S7-1200 PLC. When I trying to create a Device, the device model (i.e. S7-1200) wasn't updated in the drop down list. Consider the below picture to ensure.

But, samething I have done using KEPServerEX 5. It was working perfectly. I can receive data from PLC to LV through datasocket. Why I couldn't connect to PLC, when I using NI OPC Server 2009 ???

Thanks in Advance.

Regards,

Vijay
