Please note the following points:
• The controller generates the TLS certificate during its startup phase.
• The certificate uses the IP address of the Ethernet interface with PROFINET control-
ler function.
• The certificate is used for all Ethernet interfaces of the controller.
• Each IP address assigned to the controller must be permitted in the web browser
before a PLCnext Engineer HMI application is accessed via the address and there-
fore via the corresponding Ethernet interface.
• The certificate is regenerated after the controller is reset to factory settings.
• The certificate and a private key are located in the following directory:
– /opt/plcnext/Security/Certificates/https/https_cert.pem
– /opt/plcnext/Security/Certificates/https/https_key.pem
