In TIA15.1upd4 I have a 1511-PN with OPC UA server enabled. No security is enabled.
I´m using PLCSIM Adv. 2.0 to simulate the PLC.
When I try to get FIO to connect to PLCSIM Advanced 2.0 SP1 using OPC Client DA/UA I get an error
I’m able to connect other OPC UA clientst to PLCSIM Advanced, like UaExpert1.5.1 using this endpoint url opc.tcp://192.168.1.200:4850 with out any problems. But it does not work in FIO.
Both FIO and PLCSIM is running with Admin rights.
Welcome to the forum!
Can you confirm that No security is the only security policy set on OPC UA > Server > Security > Secure Channel
After looking this up, it looks like the error 10013 is a Windows error (WinSock error). I found a similar issue reported at Microsoft support forum.
A common cause can be a firewall or antivirus software denying the connection to the socket. Please check whether the machine where Factory I/O and TIA Portal is running has a firewall/antivirus software installed and whether outbound TCP connections are allowed.
Hi,
Thank you for your patience and your time.
It is working now, it was a Firewall issue 
I was pretty sure that I did disable my firewall when I first experienced this issue, but apparently I did not.
(Yes I feel really stupid 
)
Thanks again for your support…
Can I somehow mark this thread as “Solved”?
There is no way to mark a thread as solved.Your feedback is enough.
Thank you
