FOUNDATION Fieldbus Technical Specifications

FOUNDATION FIELDBUS TECHNICAL SPECIFICATIONS

The FieldComm Group is the developer, owner and standards organization for the FOUNDATION™ Fieldbus technology, establishing and controlling new developments and enhancements that support the needs of the process automation industry. FieldComm Group manages the FOUNDATION Fieldbus Technical Specifications and other related documents and provides related services and development tools to product manufacturers.

The FOUNDATION Fieldbus Technical Specifications is a complete, bookmarked, word-searchable software package that includes the latest FOUNDATION Fieldbus H1, High Speed Ethernet (HSE) and Physical Layer technical specifications. These specifications are essential for field device and controls manufacturers requiring implementation of fieldbus-based control solutions. The package also includes the latest application guides as well as technical and application notes.

      The purpose of this specification is to support the standardization of a common file format for use in configuring and maintaining fieldbus devices and their function block applications. The scope of this specification is the definition of file formats for two different purposes:

      1. Transporting information that describes all of the visible information built into a device by the device manufacturer.
      2. Transporting data about specific devices configured for specific applications.

      This specification contains the technical overview, architecture, format definition, and content of files that are common to all FOUNDATION Fieldbus host computer applications.

      The scope of this document is to establish requirements for design, implementation, test, and interoperability verification of a set of communication protocols in HSE Devices on High Speed Ethernet media. These protocols together define the Ethernet Stack.

      The HSE Presence in a HSE Device provides services for Ethernet Stack initialization, general-purpose communication over the Ethernet media, time synchronization, and HSE Presence management.

      The HSE Presence is an addition to the Fieldbus Foundation H1 system and network management model. The HSE Presence does not replace this model, but rather adds services for HSE Presence management.
      This specification is intended to encompass all the physical media and signaling rates described in IEEE Std 802.3 and IEEE Std 802.3u.

      However, conformance tests are only defined for 100 Mbit/s Fast Ethernet (IEEE 802.3u).

      Management of the HSE Presence is employing SNMP augmented to support Fieldbus Foundation unique Ethernet Stack parameters.

      The scope of this specification is redundancy as it applies to device connections to LANs and redundancy as it applies to HSE devices themselves.

      Redundancy as it applies to HSE LANs addresses communication paths that contain repeaters, bridges, switches and hubs and device connections to those communications paths. However, because routers interconnect LANs, they are not included within redundant HSE LAN communication paths. The HSE LAN redundancy addresses communication paths among HSE Devices as well as non-HSE devices.

      Redundancy as it applies to HSE devices themselves addresses devices that operate as backups to other devices.

      This document provides a technical overview of the approach to LAN and device redundancy followed by details of the mechanisms for achieving LAN redundancy and the behaviors of redundant devices. The annexes provide a copy of relevant message contents, together with informative discussions of the LAN redundancy mechanism, LAN topologies, LAN redundancy implementation considerations, the responsibilities of a configuration application and a summary of the effects of the configuration parameters.

      The intent of this document is twofold:

      • to apply the appropriate parts of the IEC 61158-2 standards to Fieldbus Foundation devices by referencing those parts without changing any of the defined signaling and electrical (or optical) parameters. The IEC 61158-2 standards take precedence over this Fieldbus Foundation profile in the event of any conflict of requirements.
      • to address Intrinsic Safety applications using either the traditional Entity model or the newer Fieldbus Intrinsically Safe Concept (FISCO). The mixing of the Entity model with the FISCO approach in the preparation of a system design is not recommended.

      The scope of this documentation is limited to conformance testing and excludes performance testing and interoperability testing. The introductory part presents a framework and methodology, based on ISO/IEC 9646, for testing conformance to the FOUNDATION Fieldbus specification. This provides sufficient information to facilitate test laboratory facility and equipment planning. The approach is independent of the test tools (equipment and software) which the users of the documentation might select for the purpose. Guidance for procurement of such tools is provided by indicating key parameters and their test equipment requirements. The present FOUNDATION™ Physical Layer profile is limited to a bit rate of 31.25 kbit/s. Future bit rate increases to 1 Mbit/s and 2.5 Mbit/s will require higher specification test equipment.

      The purpose of this specification is to allow the field devices of any manufacturer to receive software upgrades from any host. The software upgrade for a device may consist of one or more binary images. The following sections describe the procedure for downloading one or more binary images without regard to their purpose or content.

      This Common Software Download Specification (CSDS) is independent of the device architecture. The specification only specifies the services, objects, and the object behavior associated with downloading software to a device. It does not address system issues such as security, user interfaces, etc. This addendum does not preclude alternate means of upgrading software. The format of the binary image (syntax and semantics) is outside of the scope of this specification. Vendors may have proprietary syntax and semantics in this image to support, for example, incremental downloads or downloads of specific blocks.

      Support for this Common Software Download procedure is optional.

      The purpose of this specification is to support the standardization of function block definitions for use in function block applications. The scope of this specification is to define:

      1. the characteristics of function block applications and their function blocks
      2. a base set of function block types, and
      3. a mechanism for the definition of specialized function block types by user groups and device vendors.

      This specification consists of five parts:

      • Part 1 - contains the introduction, technical overview, architecture, formal models, operation descriptions, and mapping to FMS.
      • Part 2 - contains the block parameter and implementation details for an initial set of ten function blocks and the resource block. These definitions meet basic measurement and control requirements.
      • Part 3 - contains the block parameters and implementation details of blocks to address more advanced calculation. Also, blocks are included for device control and discrete processing which meet many requirements of the process industry.
      • Part 4 - contains components added to the Part 1 architecture and model to address special requirements of manufacturing automation.
      • Part 5 - contains components added to the Part 1 architecture and model to address special requirements of user applications.

          This document provides a conversion from HART engineering unit codes to FOUNDATION™ fieldbus engineering unit codes. Since some HART engineering units  are not represented in FOUNDATION™ fieldbus, the conversion for those engineering  units is blanks (no units). The table does not provide a reverse mapping from  FOUNDATION™ fieldbus to HART since it is intended to permit only a HART configuration or maintenance tool to change the engineering units in the HART device. Therefore, the FOUNDATION™ fieldbus viewer has a read-only view of the engineering units converted into FOUNDATION™ fieldbus engineering units.

            The purpose of this document is to describe application guidelines for building devices and hosts and to identify specification enhancements which improve the user experience when replacing devices. It is also expected that less end-user’s knowledge about Foundation Fieldbus intricacies are required and that such replacement becomes faster and does not disturb the network. The intention is to simplify the functionality of reproducing a existing FF device configuration (all FBs and parameters) onto a new FF device to allow quick device replacement (FCG_AG30181).

            The main purpose of this document is to provide a common set of test cases to reduce multivendor interoperability issues in end user systems and assist in meeting end user  expectations from multivendor solutions. These common tests will allow device and host developers an expectation of what areas may be tested with a host system with a particular device. These test cases will allow the developer to test their product in an
            effort to progress development of their device before release or allow for expected standards for external testing with host systems. These test cases are to assist in identifying usability and interoperability issues in the integration of multivendor system solutions and are developed independent of any host system and any caveats of any particular system design. This document is an ongoing process and is expected to be updated with the latest functionalities within the Fieldbus specifications.

            The purpose of this document is to provide guidelines for device vendors as they develop Device Description version 4 (DD4) files for support with legacy host systems. Device Description Services (DDS) version 4 has certain size-limitations with regards to the structure of the DD binary files. A device vendor must implement and test DD4 files—to be compatible with legacy host systems—in order to register their device. In a few cases, a device’s DDs may become large enough where the Tokenizer will give error when trying to build the binary file and the vendor will not be able to proceed with registering their DDs. This document will provide details on the problem that can be encountered as DDs grow in size during development and it will provide guidelines that can be followed to reduce the size of the DD sufficient to build the binary and support compatibility with legacy host systems.

            The purpose of this application note is to illustrate how discrete variable values as defined by the DS-66 data type, are interpreted in conjunction with state tables. While this is fundamental to DO and DI blocks, it is not limited to those blocks, but will be used in conjunction with all DS-66 data types that have a unit relationship that is either a constant or defined by a unit relationship with a state variable.
