Industrial Applications

1. Secured Site-to-Site VPN Gateway for Industrial Branch Offices

Establish secure encrypted links between remote warehouses, utility stations, or manufacturing plants and the central corporate headquarters. The router handles up to 10 IPSec VPN tunnels simultaneously, allowing secure data acquisition and industrial control monitoring over public networks [1.2.6].

Problem Solved

Protects sensitive telemetry and operational data over public internet networks without requiring a separate high-cost firewall appliance.

2. Integrated Local Network and Wireless AP Control for Manufacturing Floors

Deploy robust, reliable Local Area Networks on shop floors where multiple machinery and tablets need connection. The TL-R476G controls up to 50 external TP-Link APs and serves up to 100 concurrent devices, enabling seamless handover for automated guided vehicles (AGVs) and staff handhelds.

Problem Solved

Eliminates the complexity and hardware cost of dedicated wireless LAN controllers by embedding AP management functionality directly into the network edge router.

3. Regulated Edge Gateway with Traffic Control for Distributed PLC Networks

Install as a localized control room router to partition industrial automation networks. Using built-in access control lists (ACLs), MAC filtering, and advanced internet behavior management, engineers can restrict PLC and HMI terminals from unauthorized external connections while keeping firmware updates manageable.

Problem Solved

Prevents operational disruptions and cyberattacks caused by unauthorized internet access from field-deployed HMI panels or PLCs.
