How many industrial communication protocols can an industrial AI edge gateway support simultaneously?

The industrial AI edge gateway software architecture supports simultaneous operation of eight protocols, including Ethernet, IP, Modbus, TCP, Profinet, OPC, UA, and CANopen. This concurrent protocol stack places a heavy load on the main CPU and network controller, potentially inducing power supply noise and radiation. Countermeasures include:

1) Adding LC filtering to the CPU core power supply using a common-mode inductor CML4532A-101T and a 220μF capacitor;

2) Providing independent isolation with a PBZ1608E600Z0T ferrite bead for each Ethernet PHY; 

3) Using copper braided tape for chassis grounding with an impedance <0.1Ω.

Tested by the State Grid, it passed EMC Class A for all eight protocols.
