Role of LAN in SCADA

  • Enables communication between SCADA servers, PLCs, RTUs, HMIs, and operator stations
  • Supports data sharing, monitoring, and control across the plant network
  • Provides a reliable infrastructure for real-time industrial communication

What is a LAN?

A local communication network connecting computers, controllers, and devices within a limited area (e.g., plant or facility)

  • Allows multiple users and systems to share resources and data
  • Operates at high speeds (Mbps and above) with full device connectivity
