Secure, remote monitoring and control of a PLC from AWS

This comprehensive article details how to create a secure, remote monitoring and control system for a Programmable Logic Controller (PLC) using AWS cloud technologies. The solution demonstrates an edge-to-cloud architecture for industrial operational technology (OT) environments.

• Key hardware components include:
  • Allen-Bradley Micro850 PLC
  • Teltonika RUT956 industrial cellular router
  • Revolution Pi Core SE edge device
• Major technical steps include:
  • Creating AWS Private Certificate Authorities
  • Establishing a Site-to-Site VPN with BGP routing
  • Installing Ignition Edge on the edge device
  • Configuring PLC communication
  • Setting up a cloud-hosted Ignition Gateway in AWS
• Security features involve:
  • IPsec encryption
  • Certificate-based authentication
  • Dynamic VPN tunnels

The architecture enables secure, remote monitoring and control of industrial assets across geographically distributed sites, demonstrating the potential of cloud-enabled operational technology.
