Split from OPC UA client - error connecting.

Upgrade

I have done many test about this connection problem.

I found out that B&R certificate has not the IP Address included but only URL and DNS.

This can explain why is not possible create a connection.

I will test with a DNS server that resolve the name of the B&R panel. I will let you know.

PLC problem could be related to different CPU time?

Hello FedericoValle_RGA

do you have tested the OPC Server access with a common test client like UAExpert?

which Security settings do you use?

Do you have set date/time on every partner (server/client), because of certificate?

Bye Murof

I have tested OPC UA client connection with UA Expert and it works.

Also from "OPC UA Interface" of TIA portal I have been able to access the server interface data.

Security is disabled...I use "NONE" as option when connecting with UA Expert.

I have encountered another issue with a PLC S71215  on another net. This problem is because I have to pass through a secomea device by NAT to reach the OPCUA server.

Solution from Siemens to change IP on server certificate is not working.

I believe part of the problem could be the firmware of the OPC client and some configuration change you have to make.

I can't find the link to the manual, but it is simply called Programming and Operating manual.

NAT Comms will only work (if you're lucky) on V2.8 of firmware and above.

Quoting from it:

So the way I read that is that you should copy the start value in the ServerEndpointUrl tag of your Client Interface Configuration DB (found in System Blocks>Program resources) and paste that into the ServerUri field of the ConnectInfo structure above it. 

Having said all of that, I've done that and still nothing. Currently trying to use GET/PUT instead but again, nothing working....
