Hello 

I'm trying to connect to S7-1200 thrue OPC instaled on PC station. I'm using this manuals: https://cache.industry.siemens.com/dl/files/679/39960679/att_117996/v3/39960679_s7-1200_opc_simatic-net_tia-portal_e.pdf 

The problems occur when a come to page 20 - adding the S7 connection.

The problem is visible on attached picture.

Any suggestion?

Thanks.

Hello vto 

where exactly ist the problem in your screen?

In a quick test Project I have already the same.

If you look in the Properties of the Connection then I should be everything OK.

You will only get ONE Connection. In the Screenshot are two (I dont know why), but its not needed.
