CW Edge Computing Gateway
CW Series
100+ industrial-protocol acquisition, 4G/Wi-Fi/Ethernet cloud channels, edge computing and rule engine, supporting source-grid-load-storage coordinated scheduling.
Product Overview
The CW Edge Computing Gateway is a smart edge access device developed by FEXLINK for industrial IoT scenarios. It comes with a built-in edge computing development engine and an open data acquisition development engine, enabling secondary development of data and custom protocols. Downstream, it collects data from PLCs, HMIs, meters, sensors and other devices via 2 RS485 channels or Zigbee; upstream, it connects to the cloud platform via wired Ethernet or wireless 4G. It delivers core capabilities including millisecond-level alarm prediction, offline buffer & retransmission, traffic saving, data encryption, and routing/switching. The metal housing supports standard 35mm DIN rail mounting, suitable for various industrial control cabinets.
