It is recommended to use a firewall between the Internet and the MindConnect Elements, this is also recommended for communication to the automation network.
In the direction to Automation Network a firewall supporting NAPT (in case of DMZ, see section “List of abbreviations”) or supporting the “Ghost-Mode” is required. Siemens offers many types of Firewalls for fulfilling these requirements.
① Corporate / Office Network with route to the internet or direct internet access, e.g. via a DSL modem
② Production / Machine Network
“Ghost-Mode”, also known as “Transparent Mode”, is used to protect individual, event alternating, devices by dynamically taking over the IP address.
