==Prerequisites==
[[File:UI_OPCUA_Certificate.png|border|thumb|Export Certificate]]
The {{UBIK}} OPC UA components are acting as an OPC Client, therefore a secure connection to the respective OPC Server needs to be established in order to be able to communicate. The security standards that need to be applied are highly dependent on the server configuration and security infrastructure, but normally at least a client certificate needs to be issued that has to be trusted by the server:
# Open a command box on the {{UBIK}} server with administrator privileges (''"Run as administrator..."'')
# Run the program ''CreateCertifcate.exe'' from the archive {{FileLink|CreateCertificate.zip|CreateCertificate.zip}}
# Open the program ''Manage computer certificates'' (typically ''C:\WINDOWS\System32\certlm.msc'')
# Navigate to ''Personal - Certificates'' and find the certificate named ''UBIK OPCUA Interface''
# Export the certificate and trust it on your OPC server
