    HOST PROFILES, CLASSES & FEATURES

    A host profile defines a minimum set of FOUNDATION-specific features that must be implemented by a host to achieve compliance to a specific host class. A host may incorporate one or more hardware and software components as defined by the host manufacturer. Currently, FieldComm Group defines five profile classes. Each of these host classes has its own set of characteristics, primary end users, and use cases. These include:

    1. Class 61 – Integrated Host: Primary, on-process host that manages the communication and application configuration of all devices on a network
    2. Class 62 – Visitor Host: Temporary, on-process host with limited access to device parameterization
    3. Class 63 – Bench Host: Primary, off-process host for configuration and setup of a non-commissioned device
    4. Class 64 – Bench Host: Primary, off-process host with limited access to device parameterization of an off-line, commissioned device
    5. Class 71 - SIF Integrated Host: Primary on-process host for Safety Instrumented Functions

    FEATURES OF EACH HOST CLASSIFICATION

    In addition to the various host classifications, each classification also has its own set of Mandatory, Optional, or Prohibited features. View the Host Features Table below for a full breakdown of Mandatory, Optional and Prohibited features of each host classification.

    TECHNICAL PAPER

    It is important to understand what host testing and registration means to the end user. We have created a technical paper specifically to help better understand the process.

    BUILDING A STRONG FOUNDATION FOR INTEGRATION

    EDDL and FDI (Field Device Integration) are the building blocks of today's and tomorrow's modern process control systems.

    EDDL

    Electronic Device Description Language (EDDL) is a programming language used to create Device Descriptions (DDs) to describe the attributes of field devices in an Operating System (OS). It is a universal, proven and state-of-the-art method of accessing diagnostic, real-time and asset management information contained in more than 30 million compliant field instruments from a host of manufacturers, and to provide optimum data and device interoperability. DDs provide device functions such as generic digital and analog input/output modules, HMI displays and transmitters, on-off and regulating valves, and closed-loop controller diagnostics.

    With EDDL technology, a user can calibrate instruments, diagnose problems, provide data for user interface displays, identify process alarms and obtain information needed for high-level software, such as MES, UI/SCADA, plant historians, asset management and ERP.

    FDI

    FDI, put simply, is the rationalization of benefits of EDDL and FDT/DTM technologies. Users requested a uniform device integration solution for process industries that combines the broad benefits of EDDL with the enhanced feature sets of FDI. This solution must also span across all host systems and devices regardless of manufacturer. Thus, FDI was born. FDI device packages make it easier for automation suppliers to develop and integrate intelligent devices, because suppliers only need to create a single, unified package for each intelligent device that can work with all host systems and tools. This reduces overall development costs, while preserving and expanding existing functionality. Users will also find it easier to manage information from intelligent devices with a single device package, instead of juggling different technologies and investing significant capital in custom integration efforts to connect multiple technology platforms.

    FIELDBUS AT THE SPEED OF ETHERNET

    FOUNDATION Fieldbus High Speed Ethernet (HSE) enables tight integration and a free exchange of information needed for the plant enterprise. HSE is a superior solution to proprietary, Ethernet-based technologies since it provides end users with interoperability between disparate controllers and gateways in the same way that H1 supports interoperability between transmitters and actuators from different suppliers. And like H1, HSE is an international standard (IEC 61158).

    HSE functions as a control network technology specifically designed for process automation to connect higher-level devices such as controllers and remote-I/O, high-density data generators, etc., and for horizontal integration of subsystems.

    FOUNDATION HSE is ideally suited for use as a control backbone with capabilities for device, subsystem and enterprise integration. The HSE implementation employs a transfer rate of 100 Mbit/s and can be used for connecting hosts like Distributed Control Systems (DCSs) and linking devices via standard Ethernet cabling including fiber optic. It employs a full-fledged redundancy scheme giving control systems greater availability than systems using simple ring-topology. Use of unmodified Ethernet and standard IP makes HSE systems more cost-effective than other Ethernet solutions and proprietary networks. Since HSE is a standard, it enables simple and tight integration between package units and the main control system. The HSE network is easier and cheaper to manage based on common network knowledge and standard SNMP tools.
