Copying Certificates to the Trusted Certificates Store
When establishing the connection to an OPC server, you may be required to copy the DeviceXPlorer OPC Server and FrameWorX™ Server certificates to the OPC Foundation trusted certificates folder.
To copy certificates to the OPC Foundation trusted certificates folder:
-
Get the Device Explorer certificate file from the OPC UA server properties saved in a folder in C:\ProgramData. In our example setting, it is C:\ProgramData\TAKEBISHI\DeviceXPlorer OPC Server 7\pkiserver\own\certs\DxpOpcUaServer.der.
-
Get the FrameWorX Server certificate file from C:\ProgramData\ICONICS\11\pki\own\certs.
-
Copy and paste both files to C:\ProgramData\OPC Foundation\UA\pki\trusted\certs.
If you need to revert the changes, just delete the certificates from the C:\ProgramData\OPC Foundation\UA\pki\trusted\certs folder.
