Administration - Certificate tab

On the CERTIFICATE tab you make all settings around the certificates.

CA certificate

If you use the internal GDS, the CA certificate is already pre-entered. 

The CA certificate is the root certificate from which the Device and Update Management derives further certificates. If you regenerate the root certificate, the Device and Update Management practically has a new identity. Therefor, you should only enter it once or regenerate it after a security incident. 

If you don't have a PKI and don't want to use the certificate management from the Device and Update Management, you can upload your own certificates. 

For the certificate you have to enter a validity duration. 

The GDS server is also the OPC UA® server used by the Device and Update Management client. The server needs an own certificate. Based on the above CA, a certificate is generated for the GDS server. 

When all certificates are set, they are visible in the OPC UA® applications area in the certificate details. 

Certificate management

In this area you see all applications which have received a certificate from the DaUM GDS.

With the Revoke button you can revoke the respective certificate of the device.

Note: After you have used the Revoke button, the device is then no longer accessible via the Device and Update Management because it is no longer trusted. To be able to reach it again, you must reset the device.
