Hallo everyone,

I'm trying to using UaExpert to connect to the OPC/UA Server on my Raspberry Pi, but I get an error message

DiscoveryUrl of FindServers (opc.tcp://192.168.1.108) differs from the one received in GetEndpoints (opc.tcp://raspberrypi:4840)
Could not connect to server: BadCommunicationError

also showing in the following attachments.

Does anyone know how to connect to the OPC/UA Server on my Raspberry Pi?

Best Regards,
Leon

You should mandatorily use the ip adress. You can change the name into the ip and that should work;

opc.tcp://192.168.1.108:4840

Hallo h-hermsen,

thank you very much for yuor help.

You mean that I should change the name into the ip(opc.tcp://192.168.1.108:4840). I have done in Server Settings as the first screenshot in the added attachment. Is that right?

But I still can not connect UaExpert to OPCUA Server on Raspberry Pi and I get new error message as the second screenshot in the added attachment. Can you help me? This is very important for my work. Please...

Hallo,

I can only add one screenshot every time.

Above I add the second screenshot as I described.

Now I add the first screenshot as I described.

Hallo h-hermsen,

I have followed the instruction of the link you sent me.

But when I Click View -> Security Screen, I can not find the Devices tab as shown in the attachment.

use the CODESYS Installer ("c:\Program Files (x86)\CODESYS\APInstaller\APInstaller.GUI.exe" )
to install the Security Agent.
