Industrial Applications

1. Branch-to-HQ Secure Industrial Network Aggregation

Industrial enterprises with distributed pump stations, telemetry sites, or branch warehouses need to send real-time SCADA and ERP data back to the central server. The TL-ER6110G utilizes its support for up to 100 IPSec VPN tunnels and its hardware-accelerated dual-core 1GHz 64-bit network processor to establish secure, encrypted site-to-site tunnels. It can aggregate data from multiple remote PLCs and RTUs without degrading network throughput.

Problem Solved

Addresses the threat of industrial espionage and unauthorized control over WAN connections by providing hardware-encrypted, low-latency VPN tunnels (IPSec, L2TP, PPTP) that secure telemetry and control traffic between central systems and remote industrial nodes.

2. Distributed Factory-Floor Wireless Infrastructure Management

Modern smart factories employ automated guided vehicles (AGVs), handheld barcode scanners, and IoT sensors that require seamless wireless roaming across the production floor. The TL-ER6110G features an on-board Access Controller (AC) that automatically discovers and manages up to 100 TP-Link enterprise wireless Access Points (APs). It distributes configurations, manages VLANs (IEEE 802.1Q), and maintains high-density coverage across the plant floor.

Problem Solved

Eliminates the complexity and high cost of separate wireless controllers on the factory floor while guaranteeing high-speed roaming and network segmentation (VLANs) to prevent industrial broadcast storms from interrupting critical automation tasks.

3. Substation Control Room Gateway with Fanless Rackmount Reliability

In power substations or municipal water treatment facility control rooms, networking hardware is mounted inside standard 19-inch server racks and must operate continuously without active air filtration. The TL-ER6110G features a 1U steel rack-mountable enclosure with passive natural cooling (fanless design) and a wide 100-240V AC universal power input. It acts as the local area network gateway, handling up to 150,000 concurrent sessions from diagnostic equipment and logging PCs.

Problem Solved

Prevents hardware failure caused by dust buildup in cooling fans, a common point of failure in dusty or harsh industrial server racks, while ensuring stable gateway performance under continuous, heavy logging and diagnostic data flows.
