Hi Guys

I am trying to connect s7-1200(CPU 1214C FW4.2) to laptop(TIA V15.1) using OPC server(SW 15..).

I follow the instructions in last part of (page 35 onward) of

https://cache.industry.siemens.com/dl/files/679/39960679/att_117996/v3/39960679_s7-1200_opc_simatic-net_tia-portal_e.pdf

when I get to Establish connection to OPC server(page 68), and click on UA server. It displays" Local UA server Could not open UA TCP request channel" in red colour.

Any ideas?

Thanks

Hello,

maybe helps...

OPC Scout: UA server Find servers error: Could not open UA TCP request channel.

Thank you Smoky

Tried the suggestions on the link, no luck.

Also down loaded S7-1200 configuration using TIA V15.1 and PC-station configuration using Step7 5.5. With this method SIMATIC NET OPC server runs and shows under COM with DA access in OPC scout V10, but can not access any of the objects(I,Q,DB, ...) of the PLC (quality bad).

There is no antivirus software on the PC and all fire wall turned OFF

Hello Arcarc

so do you want to use OPC UA or OPC DA (DCOM Based)??

Because in your posts there are mentioned both
