Connection of Siemens S7-300 PLC to NI OPC Server 2012

[Gevorg]

Hi,

My name is Gevorg.

I am going to create a communication between S7-300 (CP 343-1 Lean) and NI OPC Server 2012.

As per my investigations, NI OPC server does not have appropriate drivers for S7-300 PLCs. At the other hand I could find any documentation, that prooves that S7-300 supports OPC protocol.

Does anyone have any experience of using S7-300 PLCs?

What protocol does it support?

Could you please help me..

Attached you can find the datasheet of S7-300 PLC.

Thank you in advance,

Hi Gevord,

According to this link, NI OPC does support your PLC model. You can follow these steps.

Dear Carmen,

Thanks for the answer. I want to clarify if NI OPC does or does not support my PLC model?

Becuase there is only S7-200 in NI OPC Server.

Thanks
