Protocol compatibility: Supports both EtherNet/IP (Industrial Ethernet) and Modbus TCP (Universal Industrial Protocol), seamlessly integrating multiple brands of devices.

Network Expansion: Three Ethernet ports support daisy chain cascading, reducing the number of switches and lowering cabling costs; Support ring network redundancy to enhance network reliability.

Diagnosis and maintenance: LED indicator lights display real-time module, network, and I/O status; Support remote diagnosis, firmware upgrade and configuration, simplify maintenance.

System integration: Adapt to the full range of Quantum I/O modules (discrete, analog, and special function modules) to build a flexible distributed control system.

5、 Typical application scenarios

Process industry: chemical, water treatment, oil and gas, energy (power plants/stations)

Factory Automation: Automotive Manufacturing, Electronic Assembly, Food Packaging, Logistics Sorting

Infrastructure: Rail transit, building automation, large-scale HVAC systems

High reliability system: occasions requiring redundant communication, remote monitoring, and distributed control

6、 Installation and configuration points
