    Study Notes

    Fault Tolerant Ethernet (FTE)

    • A robust networking solution for Honeywell's Experion PKS, providing fault tolerance, performance, and security for industrial control applications.
    • FTE leverages IT technology to reduce costs on FTE network infrastructure, connectivity to IT networks, connection to third-party Ethernet devices, and maintenance and support.
    • Provides a single network resulting in a rapid response time with a switchover time typically under one second.
    • Offers full hardware redundancy in a single network simplifying management and providing consistent configuration and performance.
    • Enables analytical, diagnostic, and security tools to access the entire network from a single connection for a comprehensive view of the communication system.
    • Designed for determinism and security, ensuring each device only sends and receives appropriate message traffic, guaranteeing sufficient bandwidth for all devices.
    • Security is deeply embedded in the FTE network - the Series C Control Firewall prevents inappropriate messages from reaching Level 1 control and I/O devices.
    • Switches are configured to allow only servers to be accessed from higher-level networks.
    • Firewall or router configuration ensures only designated plant information network (PIN) nodes can access Experion servers.
    • Known for its flexibility and performance with each switch port configurable for 10 or 100 Mbps.
    • A fully switched network without hubs enables multiple messages to be processed simultaneously.
