Certificates |
During E3 installation, a certificate relative to this instance of an E3 OPC UA client is installed. This certificate is needed whenever using a connection with a server whose security mode (the SecurityMode property) is not equal to None, that is, a secure OPC UA connection.
This certificate can be found on CertificateStore/certs folder of E3 installation, as a file called Elipse E3 UA Client [xxx].der, where xxx is a random-generated code.
If this certificate is deleted, a new one is automatically generated whenever an OPC UA Driver tries to establish a connection with a server.
NOTES |
•Deleting a certificate may imply in updating OPC UA servers with a new certificate, or else a secure connection with E3 client may be denied. •This certificate corresponds to a client's instance, not to an E3's OPC UA client, that is, it CANNOT be copied from one machine to another. Every installation has its unique certificate. •E3's OPC UA client accepts any valid server certificate, that is, no configuration is needed for an E3 client to accept a certain instance of an OPC UA server. |
