Product Overview

Industrial Edge Gateway runs at the industrial edge to bridge OT devices ↔ IT systems — unified southbound access, local edge processing, and flexible northbound integration in a single gateway. 13 southbound protocols write into ShadowCore (runtime SoT), then fan out to virtual devices, edge rules, persistence, and northbound — backed by industrial-grade SLA and Soak verification.

  • Unified access: heterogeneous PLCs, meters, building and network devices — one gateway for collection
  • Shadow SoT: in-memory ShadowCore shared by UI, edge compute, and northbound
  • Edge intelligence: local rules and derived tags for control linkage and reduced uplink traffic
  • Open integration: cloud platforms, SCADA, and enterprise apps with reverse write/control
  • Industrial-grade stability: built-in metric gates, Soak regression, and CI five-gate verification
