The OPC UA connector installs a self-signed certifcate that identifies this specific installation of the connector. OPC UA servers need to trust this certificate before a data exchange can occur. The certificate is different for each installation and is sent to OPC UA servers when the connector connects. The self-signed certificate is issued with a validity period of three years.
View instance certificate¶
Goto the configuration node in the navigation tree to view the instance certificate. The instance certificate is always trusted by the OPC UA connector itself.
Configure instance certificate¶
You can renew the certificate, import a different certificate as a replacement, or export the currently used certificate by clicking on the corresponding toolbar button. Be careful when renewing or replacing a certificate because OPC UA servers that trust the old certificate will not recognize the new certificate. A warning is shown before renewal or import of a certificate and you have to confirm that you wish to proceed.
