hy guys, i want to make a connection between wincc advanced v13 and a plc from B&R using OPC UA.

opc scout connects ok, i can browse server. from WINCC editor i can also browse server, insert tags in editor.

but the runtime doesn't connect. it says connection interrupted

there is no security on the opc server.

there is no rejected certificate in c:\ProgramData\Siemens\CoRtHmiRTm\OPC\PKI\CA\ 

------------------------------------------------------------------------------------------
Split from opc ua client .

Hello

do you have checked also the other side. Rejected Folder or Certificate store at the Server side.

Check also my Post in this Topic with Name resolution.

 Hy,

i edited host file on my client PC. without it, scout and editor don't connect to server. 

tia portal editor brings the certicate in c:\ProgramData\Siemens\Automation\Portal V13\HMI\13.0.0.6_201.1\ReadWrite\OPC\PKI\CA\certs\

i do not have acces on the server side (B&R opc ua server...)

but presuming scout and tia portal editor connect successfully, why the runtime doesn't ?

fixed.

the problem was my windows 10.

moved to windows 7, and now everything is working.

the only thing i did is to enter in file system32/drivers/etc/hosts the ip and the name of the opc server (B&R plc name)

Hello which opc server you used I need to make this communication too and I don't know where to start

fixo.

o problema era meu windows 10.

mudou-se para o Windows 7, e agora tudo está funcionando.

a única coisa que fiz foi inserir no arquivo system32 / drivers / etc / hosts o ip e o nome do servidor opc (nome B&R plc)
