  • By accessing the Server's stored data repository
  • From the Flex Station during a process disturbance
  • What advantage does the Orion Console provide in terms of operator ergonomics?

  • It has small, standard definition screens that reduce eye strain
  • It requires operators to share screens for collaborative tasks
  • It allows for individual operator positions but lacks large displays
  • It features large 55-inch 4K screens for enhanced contextual displays (correct)

    Study Notes

    Operator Touch Panel

    • Primary interface for process control
    • Supports HMlWeb (Human Machine Interface Web) displays
    • More intuitive, direct, and faster than a mouse
    • Important for quick action in case of equipment failure

    Orion Console

    • Adjustable desktop height for sitting or standing positions
    • Reduces operator fatigue

    Distributed System Architecture (DSA)

    • Enables multiple Experion servers to share data, alarms, alerts, events, messages, and history
    • Extends a single database to very large systems
    • Effective for distributed systems, logically separate Experion systems, and combinations of the two
    • Fully utilizes redundant servers, networks, Fault Tolerant Ethernet (FTE), and is simple to configure
    • Supported across multiple software releases

    DSA Example

    • Operators at different stations connected to the same server can share graphic data
    • Servers automatically find data owners and create temporary cache points for quicker access

    Console Stations

    • Get data directly from controllers via Fault-Tolerant Ethernet
    • Provide a live window to alarms, events, and process data during redundant swaps or server failures
    • Require server for history, SCADA information, and console extensions

    Console Station Extension

    • Similar to Flex Station, but gets data from the Console Station
    • Provides live information of process controllers during redundant swaps
    • Server and Console Stations discover tags and have a dynamic cache

    Dynamic Cache

    • Synchronized automatically between Console Stations and the Server
    • Console Station still depends on the Server for SCADA data and alarms

    Experion Orion Console

    • Control room furniture for process operators, engineers, and managers
    • Honeywell's next-generation control room furniture
    • Features 55-inch, ultra-high definition 4K screens
    • Allows for contextual displays
    • Enables faster operator response
    • Incorporates an Alarm Fight panel for visual notification across the control room

    Experion Orion Console Specifications

    • Available in two sizes: 2 operating positions and 3 operating positions
    • Each operating position has a separate computer, mouse, thin client, and monitor
    • Separate power feeds for each operating position to avoid single points of failure

    TPS Integration with Experion

    • TPS points can be auto-discovered by the Experion Server TPS (ESVT) and seen by the Experion Station TPS (EST)
    • No duplicate tag configuration or maintenance required
    • TPS database automatically becomes part of the Experion PKS global database

    TPS Functionality in Experion

    • TPS process alarms appear in the Experion Alarm Summary
    • TPS alarms can be acknowledged from an Experion Station
    • TPS system alarm appears in the Experion System Status display
    • TPS events appear in the Event Summary
    • TPS messages appear in the Message Summary
    • TPS data can be incorporated into Experion PKS history and trends (requires configuration)

    Station Types and Data Flow

    • Servers receive data from their controllers
    • ESVT also connects to Local Control Network (LCN) for automatic TPS point discovery
    • Servers provide information to Flex Stations and each other through DSA
    • Console Stations get data from the Server and have a direct connection
    • ESCs can be connected to C200/C200E, C300, and UOC/vUOC controllers
    • Console Stations connected to the LCN are ESTs, connecting to UOC/vUOC, C200/C200E, C300, and LCN
    • Console Stations require the Server for information not directly accessible
    • Extension Stations get data directly from the Console Stations they're configured on
    • The dynamic cache synchronizes point information between Console Stations and their Server

    Fault Tolerant Ethernet (FTE)

    • Patented technology that makes standard Ethernet compatible with process control
    • Eliminates single points of failure
