The industrial AI edge gateway writes AI model update parameters to the PLC controller via the OPC UA server. OPC UA communication relies on Ethernet for real-time performance. It is recommended to add a common-mode inductor CMZ2012A-900T and an ESDLC3V3D3B on the PHY side. Since the PLC is often located in a high-interference environment, two levels of surge protection should be added to the gateway power port: a first-level varistor 14D391K and a second-level TVS 5.0SMDJ33CA. A common-mode inductor CML4532A-101T should be connected in series at the DC-DC input. Measured parameter transmission cycle is 10ms, EFT ±4kV with no timeout.
