Step-by-Step Siemens Remote Access Setup
- Hardware Integration: Connect the Siemens PN/IE interface port to HUBBOX LAN. Ensure the HUBBOX device is online via Ethernet, 4G/LTE, or 5G cellular connection.
- Virtual Subnet Mapping (Anti-IP Conflict): Avoid IP collisions with plant networks. HUBBOX automatically handles 1:1 NAT and virtual IP translation so you can connect to `192.168.0.1` Siemens PLCs across multiple sites simultaneously.
- Secure Tunnel Activation: Log into HUBBOX Connect app with 2FA authentication. Select your target Siemens site to open a secure TLS 1.3 encrypted tunnel.
- TIA Portal Direct Online Connection: Open Siemens TIA Portal > Extended Go Online > PG/PC interface type:
PN/IE> PG/PC interface:VPN Adapter. Click Start Search and connect directly.
Pro Tip for Automation Engineers: HUBBOX supports full ISO-on-TCP (Port 102) transparent forwarding, allowing full block upload/download, firmware updates, and PLC diagnostic traces through TIA Portal as if you were physically connected on-site.
