The core role of industrial Internet routers in the Industrial Internet of Things (IIoT) is to achieve reliable collection and transmission of massive data from industrial equipment. At Siemens’ Amberg smart factory in Germany, over 1,500 production devices are connected via industrial Internet routers, processing more than 50 million pieces of equipment status information daily (such as motor vibration frequencies within the range of 0-200Hz, temperature readings from -20°C to 150°C with an accuracy of ±0.5°C). And it transmits 1.2GB of machine vision data per second with low latency (<10ms) to the edge computing node. Compared with traditional serial communication (such as RS-485 with a maximum rate of 115kbps), this type of router supports Gigabit Ethernet (10/100/1000Mbps adaptive) and 5G modules (theoretical peak rate of 2Gbps), which increases the data acquisition frequency of sensors in the stamping production line from the minute level to the millisecond level. The visibility rate of equipment status has increased from 35% to 98%. The 2023 research report indicates that the data integrity rate of wind power projects adopting industrial Internet routers can reach 99.99%, which is much higher than the average level of 85% of traditional SCADA systems.
The key function is to perform edge computing tasks to reduce cloud load and achieve real-time control. The industrial Internet router deployed by a certain chemical enterprise is equipped with a quad-core ARM Cortex-A72 processor (with a computing power of 2.4TFLOPS) and 8GB of memory. It can run algorithm models (such as the LSTM neural network for predicting pump and valve faults) on the device end, and compress 10TB of raw sensor data per day by 98% before uploading. Michelin Tire Factory’s actual measurement shows that directly analyzing the vulcanization pressure curve at the edge of the production line (with a fluctuation threshold detection of ±0.35MPa) has shortened the time for identifying quality defects from 15 minutes to 800 milliseconds, and reduced the scrap rate by 15%. In the Intel case study, edge routing processed machine vision images (2000×1500 pixels) in just 150ms, which was 10 times faster than the cloud solution while reducing network traffic costs by 50%.
Ensuring the deterministic network performance of time-sensitive applications is of vital importance. The automotive manufacturing workshop uses industrial Internet routers with Time-sensitive networking (TSN) to allocate the priority channels defined by the IEEE 802.1Qbv standard for the control instructions of welding robots, ensuring that 128 devices synchronize their motion trajectories within a 2ms cycle (position error <±0.05mm). After the deployment of the BMW Leipzig plant, the standard deviation of the body welding accuracy was reduced from 0.8mm to 0.12mm. In the power monitoring scenario, Schneider Electric’s PM8000 series electricity meters, equipped with routers based on the IEEE 1588 precision clock protocol (±50ns accuracy), achieve millisecond-level synchronous monitoring of the voltage phase Angle (0-360°) of substations, providing real-time dynamic data with fluctuation frequencies of 0.1-2.5Hz for the smart grid.
Industrial Internet routers build a security barrier to prevent network threats. This device integrates a hardware-level firewall (throughput ≥5Gbps) and a VPN encryption module (supporting IPsec/AES-256 algorithms), protecting the transmission of PLC programming instructions in food packaging plants from man-in-the-middle attacks (ransomware attacks targeting the manufacturing industry increased by 87% year-on-year in 2022). Referring to the attack incident of a certain water plant in Ukraine in 2025, industrial Internet routers can achieve physical separation (such as the dual independent network interfaces of the Moxa EDR-G9010 series), isolate the office network (threat detection rate 30%) from the production control network (attack blocking rate 99.6%), and simultaneously record complete session logs (store 90 days of audit records). Meet the safety level requirements of IEC 62443-3-3 SL2.
The remote management function supporting the intelligent operation and maintenance system significantly optimizes resources. Through the TR-069 remote management protocol of industrial Internet routers, a certain mining group enabled engineers to manage 200 routers in the Siberian mine (distributed within a 15-kilometer radius) from the Moscow control center. The firmware update time was compressed from an average of 45 days to 8 hours. Based on predictive maintenance modules (such as ABB Ability™ solutions), the internal temperature of routing equipment (within the range of -40°C to 85°C) and power fluctuations (recording ±15% voltage deviation) are continuously monitored. Fan failures are warned 7 days in advance (with a confidence level of 95%), and the maintenance response time is shortened to within 4 hours. The application practice of Shell’s oil platform shows that this technology reduces operation and maintenance costs by 39% and increases the efficiency of network fault location by 90% (the average location time is shortened from 120 minutes to 15 minutes).
