HTTPS Connections
When making a connection to the Vertex™ VC4 HMI PC via HTTPS, it will be necessary to accept the certificate. A
message like the one using Google Chrome will be shown:
Tap on the Advanced button, and select "Proceed to <some IP> (unsafe)."
External Network Security Considerations
The Vertex™ VC4 HMI PC is intended ONLY for connection to a private network – no connections from the
internet should be allowed. All services not explicitly named above are disabled and filtered via the iptables
rules. Access control is via users and roles defined in the security configuration. By default, anyone can view
system state information, but elevated permissions are required for any configuration, control, or
maintenance.
NOTE
Router with IPSec or Peer-to-Peer (P2P) Network is recommended to enhance security on Modbus TCP/IP
communication.
