Rosemount 475 Working Principle

The 475 connects in parallel to a 4–20 mA loop carrying a HART-compatible instrument, or to a FOUNDATION Fieldbus segment. HART signalling superimposes a 1200 / 2200 Hz FSK waveform on top of the analog current, letting the communicator read and write device parameters without disturbing the primary measurement.

Once connected, the 475 loads the device’s DD (Device Description) from its system card, displays the live readings, and lets the technician configure range, damping, units, tag, and all device-specific settings. Configuration data can be saved, copied between identical devices, or exported to AMS Device Manager.

Compatible with HART 275, HART 375, and all imported / domestic devices running HART protocol on 1151, 3051, EJA, ABB, and similar platforms.

even when it is being used to power other devices in the field.

Intrinsic Safety to Follow You Anywhere

The Trex communicator is built to go wherever you may need to be.

Unlike consumer mobile devices that cannot be taken into hazardous areas,

without shutting down the processor pulling a hot work permit,

the Trex unit meets global Intrinsic Safety requirements:

  • ATEX
  • CSA (US/Canada)
  • IECEx
  • FISCO

Gain freedom and flexibility with a communicator,

that can go anywhere you need to, when you need to,

without worrying if the device will put you at risk.

Power the Loop

The Trex communicator includes built-in functionality to power a device.

Simply connect the communicator to an instrument to power it.

Technicians no longer waste time rounding up a power supply or confirming adequate loop resistance before testing,

speeding configuration on the bench.

Power the loop functionality allows device configuration in the field on new projects
—even before power and I/O infrastructure are in place.

Transmitter configuration no longer needs to be the last step of new projects.

Configure transmitters before the host system, wiring, piping,
and other project elements arrive,

keeping transmitter configuration from being a critical path item,

allowing more flexibility in new project scheduling and leading to faster startups.

Powering devices from the communicator,
allows you to isolate the device from the rest of the system,

helping you identify installation problems like power supply,
wiring, I/O card, and configuration issues.

Powerful Valve Diagnostics

Valve problems are particularly costly to diagnose and repair.

Field technicians are often required to pull a valve to investigate a problem,

and removing valves for inspection usually means shutting down the process.

Further complicating troubleshooting, technicians often need to disassemble the valve,

to determine the root cause of the problem.

This frequently leads to further damage to the valve,

ending in a more time consuming and expensive repair.

Using the ValveLink Mobile app on the Trex unit,

you can perform valve diagnostics in the field,

including valve signature, dynamic error band, PD one button sweep,

and step response,

without having to pull the valve or perform invasive troubleshooting steps.

ValveLink Mobile works with HART and Foundation Fieldbus Fisher® FIELDVUE™ digital valve controllers

and provides an intuitive user interface that is easy to understand and use.

The large touchscreen on the Trex communicator makes it easier

than ever to see all valve diagnostic details.

Diagnose Communication Problems

The Trex communicator can configure and troubleshoot Foundation Fieldbus devices,

and segments in your plant.

Use the communicator to create a quality segment,

by diagnosing the network DC voltage and average noise.

Detect power supply problems using the communicator’s power the loop functionality,

or by monitoring low-frequency noise on a segment.

You can also verify whether the DC voltage is correct in HART loops.

What is the default level of support for Trex units?

Beginner’s Guide for HART Protocol

Posted on by
RFQ

The HART protocol is the most trusted communication protocol in recent years. It combines the characteristics of analog systems and digital control systems.

Field instruments in process plants are beginning to be subject to more complex metrology regulations. Most new field instruments are now smart digital instruments. HART is widely used in process and instrumentation systems, such as smart HART pressure transmitters.

What is the HART protocol?

The full name of HART protocol is Highway Addressable Remote Transducer Protocol. This open standard for fieldbus communication was introduced by Fisher-Rosemount in the 1980s.

In order to solve the communication problem between industrial field intelligent instruments and control systems. The FSK (Frequency Shift Keying) frequency shift keying signal based on the Bell202 standard is used to superimpose an audio digital signal with an amplitude of 0.5mA on the traditional 4-20mA analog signal for two-way digital communication.

HART communication will not interfere with the analog signal transmitted to the control system. It ensures compatibility with existing analog systems. It is a transitional product in the process of transforming from analog systems to digital systems.

Benefits of HART protocol

Compatibility: HART protocol can be used to connect all types of field instruments, including temperature, liquid level, pressure, flow, analyzer, etc.

Reliability: HART protocol has full-duplex communication capability. The device can send and receive at the same time, ensuring the reliability of communication.

Ease of use: HART protocol can be transmitted through the existing 4-20mA signal. No additional hardware and cables are required, which is easy to use.

Working principle of HART protocol

HART protocol usually uses 4-20mA signal for two types of communication: analog signal and digital signal.

In analog signal, 4mA corresponds to the minimum value of instrument signal. 20mA corresponds to the maximum value of instrument signal.

In digital signal, the device can send digital instructions to the instrument. The instrument can also send complete measurement data and fault diagnosis information.

Digital signals can be separated and analyzed through HART system, which improves the performance of the system and reduces the cost of field instruments.

Application examples of HART protocol

  • Equipment adjustment: Through HART protocol, the parameters of field instruments can be adjusted remotely to achieve rapid adjustment of equipment.
  • Fault detection and diagnosis: HART protocol allows equipment to obtain the measurement data and fault diagnosis information of the instrument, which helps to find and solve equipment faults in time.
  • Valve control: According to the measurement data, the state of the inlet (outlet) valve can be controlled through HART protocol to achieve precise flow control.

If this article still can not explain the HART PROTOCOL for you, you can learn more about Highway Addressable Remote Transducer Protocol

HART protocol specification

As an open, compatible, stable and reliable communication protocol, HART protocol has been widely recognized and applied in the industrial field.

After decades of continuous evolution, multiple versions have been updated and improved. Each revision brings new technologies and functions while being compatible with previous versions to meet the ever-changing development needs of industrial automation.

The main functions and differences of the current mainstream versions HART 5, HART 6 and HART 7 are as follows:

①Protocols before HART 5:
Physical layer: RS485;
Link layer: Token master-slave question and answer mode;
Application layer: define some simple general commands.

②HART 5 version protocol:
Physical layer: analog current + FSK, 1200bps;
Link layer: token master-slave question and answer mode, adding a second master device and a slave device burst mode;
Application layer: further enriches general commands, ordinary commands, special commands, and short address range 0 to 15.

③HART 6 version protocol:
Physical layer: Added current C8PSK, 9600bps specification;
Application layer: Expanded command content, used extended user identification, added device cluster command, short address range 0~63.

④HART 7 version protocol:
Physical layer: Added 2.4G DSSS O-QPSK 10dBm 250kbps specification;
Link layer: Added time division multiple access (TDMA) link control mode;
Network layer: Added self-organization, multipath, mesh network specifications;
Application layer: Expanded device cluster command, added mesh network maintenance command.

hART protocol vs modbus

Modbus protocol and HART protocol are two different industrial communication protocols, which have the following differences:

Modbus protocol is a request/response protocol. That is, a master device can send request information or write data to multiple slave devices. The slave device will reply or execute only when it receives the request from the master device. HART protocol is a hybrid protocol that combines analog and data signals. That is, a digital signal is superimposed on the 4-20mA analog signal to achieve two-way data transmission and remote control.

Modbus protocol supports multiple physical layers and transmission modes, such as RS232/RS485/RS422, TCP/IP, wireless, etc. HART protocol mainly uses RS485 physical layer, and can also use wireless physical layer, but does not support TCP/IP transmission mode.

Modbus protocol can transmit multiple variables and information. The data type is limited and the number of nodes is limited. HART protocol can only transmit one primary variable and some secondary variables, device status and configuration data, with rich data types and unlimited number of nodes.

Modbus protocol is an open, compatible, flexible, easy-to-use protocol with no security guarantee. The HART protocol is an open, compatible, stable and reliable protocol with certain security guarantees.

More Measurement Solutions

HART is one of the most widely used bus protocols for industrial field devices. In addition, there are also common modbust protocols, Profibus protocols, FF Foundation bus protocols, etc.

Our simple introduction here cannot fully summarize such a protocol. There are still many details that are not included. For example, variable management, diagnostic definitions, etc. Please refer to the HART standard for specific development.

We Sino-Inst supply various process instruments with HART protocol. Including HART pressure transmitters, flow meters, level meters, etc. If you need to purchase, or have related technical questions, please feel free to contact our sales engineers!
