What is Fieldbus?
Fieldbus is seen as many things by many people and some users incorrectly regard fieldbus and device networks as one and the same. It is important to clearly understand the differences.
The growth of digital communications technology has led to a vast array of device-level network options which can be categorized as either sensor/actuator bus networks or CAN-based I/O and control networks. While suitable for discrete automation tasks such as counting and sorting, these networks lack a User Layer that is necessary for PID and other process automation tasks.
Fieldbus, however, is an all-digital, serial, two-way communications system that interconnects measurement and control equipment such as sensors, actuators and controllers. At the base level in the hierarchy of plant networks, it serves as a Local Area Network (LAN) for instruments used in process control and manufacturing automation applications and has a built-in capability to distribute the control application across the network.
The demand for fieldbus technology is being driven by manufacturing end users' desire to move away from older, centralized plant control strategies to distributed control in the field. End users want an enabling technology that provides true device interoperability, enhanced field-level control and reduced installation costs. Suppliers want to base their new product developments on an open, non-proprietary fieldbus protocol that is available to any company that wishes to implement it. |

Some extract from filedbus.org
About FOUNDATION Technology
FOUNDATION fieldbus is an all-digital, serial, two-way communications system that serves as a Local Area Network (LAN) for factory/plant instrumentation and control devices. The fieldbus environment is the base level group of the digital networks in the hierarchy of plant networks. FOUNDATION fieldbus is used in both process and manufacturing automation applications.
Unlike proprietary network protocols, FOUNDATION fieldbus is neither owned by any individual company, or regulated by a single nation or standards body. The technology is controlled by the Fieldbus Foundation, a not-for-profit organization consisting of more than 100 of the world's leading controls and instrumentation suppliers and end users. |

FOUNDATION Fieldbus™ - the path to the future
The Internet is having a major impact on information flows. Yesterday's hierarchical systems with vertical information flows are being replaced by systems that have a flatter structure and more diverse information flow patterns. In today's world, it is essential to construct networks that are integrated with the Internet and can make use of the information available on it.
More and more today, process instrumentation is being field networked. As both the quantity and quality of field information increase, new instrumentation technologies will surely develop. The following table summarizes the key differences between conventional systems and field networked systems.
Field wiring Information flow Quantity of information Information type Control functionality Maintenance location Maintenance type
Conventional 4 to 20 mA system Point-to-point Unidirectional Single data value Measurement numerical value Centered on a control system Mainly in the field Corrective maintenance
Field network Multi-drop Bidirectional Multiple data values Various data types Optimally allotted to control system and/or field devices From a remote location Predictive maintenance
The field signals used in process instrumentation have been standardized so that control systems and field devices from a variety of suppliers can be interconnected using standard 4 to 20 mA analog signals. The FOUNDATION fieldbus™ standard developed by the Fieldbus Foundation™ constitutes the next level of standardization and it is designed to meet modern needs. In addition to having interconnectivity equivalent to that available using 4 to 20 mA analog signals in a conventional field network, FOUNDATION fieldbus™ allows multiple devices to be connected to a single FOUNDATION fieldbus™, permits the interactive communication of various types of information, and enables the distribution in the field of intelligent functions including self-diagnostics and control functionality.
When FOUNDATINO fieldbus™ was first proposed, more attention was given to its ability to convey multiple field signals over a single cable and the benefit this would have in reducing wiring costs. But now the focus is on its ability to transmit various types of information in addition to field signals and to distribute intelligence to distributed field devices. These features enable remote monitoring, real-time self-diagnostics, and proactive maintenance of field devices, as well as plant resource management using field communication. This will enable the costs of operating instrumentation systems to be greatly reduced.

Glossary of FF Terms
Basic Device:
- A Basic Device is any device not having the capability to control communications on an H1 fieldbus segment.
Capabilities File:
- A Capabilities File describes the communication objects in a fieldbus device. A configuration device can use Device Description (DD) Files and Capabilities Files to configure a fieldbus system without having the fieldbus devices online.
Communications Stack:
- A Communications Stack is device communications software which provides encoding and decoding of User Layer messages, deterministic control of message transmission, and message transfer.
Connector:
- A Connector is a coupling device used to connect the wire medium to a fieldbus device or to another segment of wire.
Control Loop:
- A Control Loop is a group of Function Blocks (FBs) that execute at a specified rate within a fieldbus device or distributed across the fieldbus network.
Coupler:
- A Coupler is a physical interface between a Trunk and Spur, or a Trunk and a device.
Data Link Layer (DLL):
- The Data Link Layer (DLL) controls transmission of messages onto the fieldbus, and manages access to the fieldbus through the Link Active Scheduler (LAS). The DLL used by FOUNDATION fieldbus is defined in IEC 61158 and ISA S50. It includes Publisher/Subscriber, Client/Server and Source/Sink services.
Device Description (DD):
- A Device Description (DD) provides an extended description of each object in the Virtual Field Device (VFD), and includes information needed for a control system or host to understand the meaning of data in the VFD.
Fieldbus:
- A Fieldbus is a digital, two-way, multi-drop communication link among intelligent measurement and control devices. It serves as a Local Area Network (LAN) for advanced process control, remote input/output and high speed factory automation applications.
Fieldbus Access Sublayer (FAS):
- The Fieldbus Access Sublayer (FAS) maps the Fieldbus Message Specification (FMS) onto the Data Link Layer (DLL).
Fieldbus Messaging Specification (FMS):
- The Fieldbus Messaging Specification (FMS) contains definitions of Application Layer services in FOUNDATION fieldbus. The FMS specifies services and message formats for accessing Function Block (FB) parameters, as well as Object Dictionary (OD) descriptions for those parameters defined in the Virtual Field Device (VFD).
Flexible Function Block:
- A Flexible Function Block (FB) is similar to a Standard FB, except that the function of the block, the order and definition of the block parameters, and the time required to execute the block are determined by an application-specific algorithm created by a programming tool. Flexible Function Blocks (FBs) are typically used for control of discrete processes and for hybrid (batch) processes. A Programmable Logic Controller (PLC) can be modelled as a Flexible Function Block device.
H1:
- H1 is a term used to describe a fieldbus network operating at 31.25 kbit/second.
H1 Field Device:
- An H1 Field Device is a fieldbus device connected directly to an H1 fieldbus. Typical H1 Field Devices are valves and transmitters.
H1 Repeater:
- An H1 Repeater is an active, bus-powered or non-bus-powered device used to extend the range over which signals can be correctly transmitted and received for a given medium. A maximum of four Repeaters and/or active Couplers can be used between any two devices on an H1 fieldbus network.
High Speed Ethernet (HSE):
- High Speed Ethernet (HSE) is the Fieldbus Foundation's backbone network running at 100 Mbit/second.
HSE Field Device:
- An HSE Field Device is a fieldbus device connected directly to a High Speed Ethernet (HSE) fieldbus. Typical HSE Field Devices are HSE Linking Devices, HSE Field Devices running Function Blocks (FBs), and Host Computers.
HSE Linking Device:
- An HSE Linking Device is a device used to interconnect H1 fieldbus Segments to High Speed Ethernet (HSE) to create a larger network.
HSE Switch:
- An HSE Switch is standard Ethernet equipment used to interconnect multiple High Speed Ethernet (HSE) devices such as HSE Linking Devices and HSE Field Devices to form a larger HSE network.
Input/Output (I/O) Subsystem Interface:
- An Input/Output (I/O) Subsystem Interface is a device used to connect other types of communications protocols to a fieldbus Segment or Segments.
Interchangeability:
- Interchangeability is the capability to substitute a device from one manufacturer with that of another manufacturer on a fieldbus network without loss of functionality or degree of integration.
Interoperability:
- Interoperability is the capability for a device from one manufacturer to interact with that of another manufacturer on a fieldbus network without loss of functionality.
Link:
- A Link is the logical medium by which H1 Fieldbus devices are interconnected. It is composed of one or more physical segments interconnected by bus Repeaters or Couplers. All of the devices on a link share a common schedule which is administered by that link's current LAS.
Link Active Scheduler (LAS):
- A Link Active Scheduler (LAS) is a deterministic, centralized bus scheduler that maintains a list of transmission times for all data buffers in all devices that need to be cyclically transmitted. Only one Link Master (LM) device on an H1 fieldbus Link can be functioning as that link's LAS.
Link Master (LM):
- A Link Master (LM) is any device containing Link Active Scheduler (LAS) functionality that can control communications on an H1 fieldbus Link. There must be at least one LM on an H1 Link; one of those LM devices will be elected to serve as LAS.
Link Objects:
- A Link Object contains information to link Function Block (FB) Input/Output (I/O) parameters in the same device and between different devices. The Link Object links directly to a Virtual Communications Relationship (VCR).
Network Management (NM):
- Network Management (NM) permits FOUNDATION Network Manager (NMgr) entities to conduct management operations over the network by using Network Management Agents (NMAs). Each Network Management Agent (NMA) is responsible for managing the communications within a device. The NMgr and NMA communicate through use of the Fieldbus Messaging Specification (FMS) and Virtual Communications Relationship (VCR).
Object Dictionary:
- An Object Dictionary (OD) contains all Function Block (FB), Resource Block (RB) and Transducer Block (TB) parameters used in a device. Through these parameters, the blocks may be accessed over the fieldbus network.
Physical Layer:
- The Physical Layer receives messages from the Communications Stack and converts the messages into physical signals on the fieldbus transmission medium, and vice-versa.
Resource Block (RB):
- A Resource Block (RB) describes characteristics of the fieldbus device such as the device name, manufacturer and serial number. There is only one Resource Block (RB) in a device.
Schedules:
- Schedules define when Function Blocks (FBs) execute and when data and status is published on the bus.
Segment:
- A Segment is a section of an H1 fieldbus that is terminated in its characteristic impedance. Segments can be linked by Repeaters to form a longer H1 fieldbus. Each Segment can include up to 32 H1 devices.
Splice:
- A Splice is an H1 Spur measuring less than 1 m (3.28 ft.) in length.
Spur:
- A Spur is an H1 branch line connecting to the Trunk that is a final circuit. A Spur can vary in length from 1 m (3.28 ft.) to 120 m (394 ft.).
Standard Function Block (FB):
- Standard Function Blocks (FBs) are built into fieldbus devices as needed to achieve the desired control functionality. Automation functions provided by Standard FBs include Analog Input (AI), Analog Output (AO) and Proportional/Integral/Derivative (PID) control. The Fieldbus Foundation has released specifications for 21 types of Standard FBs. There can be many types of FBs in a device. The order and definition of Standard FB parameters are fixed and defined by the specifications.
System Management (SM):
- System Management (SM) synchronizes execution of Function Blocks (FBs) and the communication of Function Block (FB) parameters on the fieldbus, and handles publication of the time of day to all devices, automatic assignment of device addresses, and searching for parameter names or "tags" on the fieldbus.
Terminator:
- A Terminator is an impedance-matching module used at or near each end of a transmission line. Only two Terminators can be used on a single H1 segment.
Transducer Block (TB):
- A Transducer Block (TB) decouples Function Blocks (FBs) from the local Input/Output (I/O) functions required to read sensors and command output hardware. Transducer Blocks (TBs) contain information such as calibration date and sensor type. There is usually one TB channel for each input or output of a Function Block (FB).
Transmitter:
- A Transmitter is an active fieldbus device containing circuitry which applies a digital signal on the bus.
Trunk:
- A Trunk is the main communication highway between devices on an H1 fieldbus network. The Trunk acts as a source of main supply to Spurs on the network.
User Application:
- The User Application is based on "blocks," including Resource Blocks (RBs), Function Blocks (FBs) and Transducer Blocks (TBs), which represent different types of application functions.
User Layer:
- The User Layer provides scheduling of Function Blocks (FBs), as well as Device Descriptions (DDs) which allow the host system to communicate with devices without the need for custom programming.
Virtual Communication Relationship (VCR):
- Configured application layer channels that provide for the transfer of data between applications. FOUNDATION fieldbus decribes three types of VCRs: Publisher/Subscriber, Client/Server, and Source/Sink.
Virtual Field Device (VFD):
- A Virtual Field Device (VFD) is used to remotely view local device data described in the object dictionary. A typical device will have at least two Virtual Field Devices (VFDs). |

The Host Interoperability Support Test (HIST) Description
The HIST Procedures document (FF-569) provides generic test procedures that would be performed or witnessed by qualified Fieldbus Foundation staff on FOUNDATION fieldbus systems as part of the Host Interoperability Support Testing (HIST).
FF-569 does not intend to define the features and components of a FOUNDATION fieldbus host. Each host is defined by the manufacturer to provide specific functions within a fieldbus network. A host could be a configuration tool, a recording device, alarm display panel, human machine interface or a combination of functionality.
In order to implement a set of applicable test procedures, FF-569 defines a set of generic FOUNDATION fieldbus host features that may be implemented within the host. A host will conform to some, or perhaps all, features as defined by the host feature checklist. However, because hosts can have various definitions, not all features may be applicable to a host implementation. Therefore, it is not expected that every host should support each feature.
Each feature contains a set of test procedures that are to be run against the host or the fieldbus system using the host. In order for a host to claim support of a feature, the host must be able to pass the test procedures defined by the feature. The features themselves are generic, therefore manufactures will derive test cases, or actual implementation steps necessary to meet the requirements of the test procedure.
Many test procedures require both features supported from both the device(s) as well as the host. Test administrators should refer to the HIST Device Data Sheet to determine if the test procedure is applicable to that specific device on the segment.

How do I catch the Fieldbus?
By : Jim Pinto,
San Diego, CA.
USA
A wide variety of networks is available in the industrial automation environment and confusion arises because their capabilities overlap. So, which "fieldbus" should YOU use? It all depends on your needs - cost, speed, complexity, compatibility with already-installed devices and future expansion requirements.

Nice huge link collection for one topic
Post them in our link section too when you get time
Also if possible contact them to get an image for their links and if possible link exchange of our site with them (I will try the same too later)
PM me the companies you will contact so that I should not contact them again
Keep up nice work of posting such good information and will make this place best for engineers |

There are certain confusing terms related to fieldbus devices.
Firmware revision - like an application version, if this is incremented (ie the manufacturer makes changes) that requires the device revision to increment.
Device revision - the overall revision of the device, these should be integers, usually represented by a hexadecimal (ie 0x02)
Device ID - a unique identifier for the device on a FOUNDATION TM Fieldbus network. This is part of an FMS Identify response message. The structure of this number is as follows:
manufIDdevicetypeserialnumber
00012310010001ABC012345678954321
Device Description file revision - each version of the DD should be tested and registered with the Fieldbus Foundation, and are then available to download from our Registered Product Catalog. The file name is made up of two parts, the device revision and file revision, the CFF has an additional file revision:
aabb.ffo aabb.sym aabbcc.cff
aa = device revision
bb = DD file revision
cc = CFF file revision
This is simple description for above terms.
I will put link of dd files for FF devices so you people can manipulate above terms. |

There is often some confusion on this. Part of the confusion may be that FF does not deal with "firmware version". FF parameters only exposes device revision and DD revision.
Firmware is the embedded software in the device. It handles FF communication but also measurement, actuation, or whatever the device is doing. It is quite possible that changes are made to the device which has nothnig to do with the FF communication. For example, a pressure transmitter may get a new verison with a better temperature compensation algorithm or better diagnostics etc. Therefore you may in fact find that a device type have different firmware version yet may still have the same device revision and DD revision.
When significant changes are done to the device, maybe new hardware, or a change that affects FF communications, the device revision will be incremented.
The DD files have a revision separate from the device itself because it is possible that some anomaly (bug) is detected in the DD file and the manufacturer may need to make a new file.
Similarly, there is also a revision number for the capability file.
It would be nice if there was a standard parameter in the resource block informing the firmware version. SMAR devices have an additional block with parameters containing firmware version and other nice to know information.
I can find only SMAR devices with this type of additional block. |

Some nice information H1 profile class
To quote FF-940:"This profile defines the minimum level of communication functionality and features that shall be supported by each of the classes. The functionality and features are chosen in a way to enable the building of fieldbus systems by the mixing of devices of different profile classes from different vendors. The communication functionality and features in each of these profile classes represents a specific combination of functionality and features selected from the Fieldbus Foundation’s Physical, Data Link, FAS, FMS, Network Management and System Management specifications. FF communications stack software can be certified as meeting one or more of these profiles. Devices may also be certified as meeting one or more of these profiles, although proper behavior of the service interfaces enumerated in this document as mandatory for a class can be tested only by inference, and not by direct observation."
A brief explanation of "H1 Profile Class":
Class 31 - Has an FBAP, is a server and will: publish data (P) and/or subscribe to data (S) and/or is a client (C)
Class 32 - link master(L) and/or system time keeper (TM)
Class 33 - supports FMS client functions
Class 34 - supports System and Network Management client functions
Class 35 - provides bridge functions |

I guess you have uploaded all the files in download section
Normally when you upload files in download section, it needs staff approval before it can appear in download section
so normally give atleast few hours to max a day before they are approved |

Dear Hemant,
Just Now, I had completed uploading all 12 parts of Foundation Fieldbus which covers all aspects of this particular communication protocol.
I think its better to delete from the forum section these 3 files above my answer.
By the way, it depends upon ur wish.
Have a nice time.
One question is there space limitations for each member for uploading files? |

As Kaushal (funduinstru) said you can edit your posts yourself and delete the files and replace them with links to your files in download section
and there is no space limitation of any kind so go ahead and post more in upload and forum section |
