Dialog: Encrypted Communication Quick Setup

Function: Encrypted communication between an Edge Gateway and one or more PLCs can be set up in the dialog. First, the PLC is searched for a qualified certificate for encrypted communication. If no qualified certificate is found, then a certificate is generated on the PLC. Then the certificate is copied to the Edge Gateway so that the Edge Gateway can trust the certificate.
