OPERATOR INTERFACE
The operator interface, commonly known as the Human Machine Interface (HMI), is a sophisticated system integral to industrial operations. Typically, it operates as a PC powered by the Microsoft Windows NT operating system, offering extensive functionality and compatibility.
CORE COMPONENTS
Operating System: Microsoft Windows NT provides a stable and robust foundation for the HMI system's operations.
CIMPLICITY Graphics Display System: This system enables the creation and visualization of graphical displays essential for monitoring and controlling processes.
Control System Toolbox: A specialized toolbox designed for maintenance purposes, aiding in diagnostic and troubleshooting tasks.
Software Interface: Facilitates seamless communication and integration with the Mark VI and other control systems within the network, ensuring interoperability and data exchange.
APPLICATIONS
The HMI system finds diverse applications across various operational scenarios:
Primary Operator Interface: It serves as the primary interface for one or multiple operational units, allowing operators to monitor and control industrial processes efficiently.
Backup Operator Interface: Capable of acting as a backup to the plant's Distributed Control System (DCS) operator interface, ensuring redundancy and continuity in operations.
Communication Gateway: Functions as a gateway for establishing communication links with other control systems, enabling seamless data exchange and interoperability.

Engineer's Workstation: Provides engineers with a dedicated platform for system analysis, development, and testing, enabling the configuration and enhancement of operational systems.
TIME SYNCHRONIZATION
All controls and HMIs on the UDH can be synchronized to a Global Time Source using time synchronization (GTS). The most common GTSs are time-processing devices like the StarTime GPS Clock or other GPS (Global Positioning System) receivers. Although GPS or UTC are the preferred time sources, a GTS that uses local time as its base time reference is also supported by the time synchronization option.
One or more HMIs equipped with a time/frequency processor board receive a time-link network from the GTS. The Mark VI(s) are synchronized to within +/-1ms time coherence using Network Time Protocol (NTP) when the HMI receives the time signal. Local signals, IRIG-A, IRIG-B, 2137, NASA-36, and other time sources are supported.
UNIT DATA HIGHWAY FEATURES
The Unit Data Highway (UDH) stands as a crucial link between Mark VI control panels and the Human Machine Interface (HMI) or HMI/Data Server, forming a foundational network for efficient data transmission. This network is established through the utilization of unshielded twisted pair cables or fiber-optic Ethernet, enabling seamless and rapid data exchange between interconnected components.
A distinguishing aspect of the UDH lies in its optional redundant cable operation, a feature designed to ensure continuous system functionality even in the face of cable faults or disruptions. This redundancy guarantees uninterrupted unit operation, as the system seamlessly switches over to an alternative cable, maintaining operational integrity. This redundancy feature holds true even in configurations employing dual cable networks, wherein the UDH operates as a unified logical network, preserving cohesion and operational efficiency across the system.
Much akin to the redundancy mechanisms found in the Plant Data Highway (PDH), the UDH system can be equipped with redundant network switches, each independently powered. This redundancy fortifies the reliability of the network infrastructure by providing failover options, minimizing the risk of system downtime due to switch failures. Furthermore, the incorporation of fiber-optic communication within the UDH system serves as an additional layer of reinforcement, elevating the robustness and efficiency of the entire network. The utilization of fiber-optic technology enhances data transmission capabilities, offering higher speeds, increased bandwidth, and greater resistance to electromagnetic interference, thereby contributing to the overall resilience and reliability of the UDH infrastructure.
THIRD-PARTY CONNECTIVITY OPTIONS FOR THE MARK VI SYSTEM
Modbus Link: The Mark VI system offers a Modbus link from the Human-Machine Interface (HMI) Server's RS-232C port to the DCS. This connection enables data exchange between the Mark VI system and the DCS using the Modbus protocol, allowing for efficient communication and control.
High-Speed Ethernet Link - Modbus over TCP/IP: Alternatively, a high-speed 10 Mbaud Ethernet link can be established between the Mark VI system and the DCS, utilizing the Modbus over TCP/IP protocol. This protocol leverages the capabilities of Ethernet communication to facilitate rapid data transmission and real-time control between the two systems.
High-Speed Ethernet Link - TCP/IP with GSM: Another option for connectivity involves utilizing a high-speed 10 Mbaud Ethernet link with the TCP/IP protocol, complemented by an application layer known as GEDS Standard Messages (GSM). This approach enhances communication efficiency and reliability by employing standardized messaging formats tailored to the requirements of the Mark VI system and the DCS.
