HART Communication protocol: Tips, Tricks & Recommendations to optimize your workload.

30/1/2023

0 Comments

 
Firstly, What is HART?
​Highway Addressable Remote Transducer, known as HART, is a communication protocol that allows users to communicate with smart devices. This is achieved by using analog wiring to communicate directly with a smart device i.e. a Burns Engineering T55 Temperature Transmitter.
This standard has been implemented since the mid-1980s and is the most popular communication protocol used today.

​Before HART was established, older devices traditionally had to be adjusted and set up by either:
  • Adjusting the span and range screws at the device.
  • Removing the casing of the device and changing out the range jumpers on the PCB.
With the establishment of the HART communication protocol, users can simply connect up to the device (as displayed below) and communicate to either a single or a multiple number of devices.

---- TIP 1 ----
Establishing the type of work and determining
what you need to achieve it
This is probably the most important aspect to consider when using or choosing the right HART communication device for your application.
With the various amounts of HART communicators available, it sometimes can be difficult to choose the correct job for the tool. For example, if a calibration technician would like to perform a pressure calibration on a transmitter, wouldn’t it be much more beneficial to have a pressure calibrator with built-in HART comms, rather than a separate communicator and calibrator?
Considerations like this will save you time and money.
Some worthwhile questions to ask yourself when choosing a viable HART communicator may be:
  • Is my HART communicator flexible and can I do other tasks with it?
  • Is it user friendly?
  • Do I have good technical support that I can trust and rely on?
  • Is there more communication protocols available like ISA100, Profibus etc.?

​---- TIP 2 ----
Don’t forget your 250 OHM Resistor!
This tip is definitely worth paying attention to! Speaking from experience there is nothing worse than preparing to do a calibration on a smart device and then suddenly realizing that there is no 250Ω resistor in the loop.
You would be correct to think that not all communicators require a 250Ω resistor within the loop but that is not always the case. If you can, always have a couple of 250Ω resistors in your pocket just in case!
​Why is it 250Ω resistor?
HART Communication technology has a very low power requirement (less than 3.8mA).
HART utilizes a frequency shift keying (FSK) modem to communicate over the primary variable analog signal wires.
By imposing the digital signal on top of the 4-20mA analog loop, HART allows for a simultaneous analog signal with a continuous digital communication signal that has no effect on the analog signal.
A minimum resistance of 230Ω is required to create an impedance with in the loop to allow for HART communication, so typically a 250Ω resistor is recommended as its easily available.
IPP’s Recommendation:
A Recommendation for a HART communication tool that is both reliable and cost conscious is Yokogawa’s Field Device management tool: FieldMate.
FieldMate  is a PC based configuration tool that performs numerous tasks, including:
  • initial setup,
  •  daily maintenance,
  • troubleshooting,
  • configuration backup for device replacement.
These task are streamlined by FieldMate's intuitive operation and integrated environment, which is independent from communication protocols and device vendors.

FieldMate supports the following communication protocols:
o BRAIN
o 
FOUNDATION™ fieldbus H1
o HART
o PROFIBUS
o 
ISA100.11a
o Modbus
​

Its user friendly design allows users to complete more complex tasks with confidence and ease. For example, with the ISA100 communication function, users can easily configure and provision wireless instruments in a matter of minutes which cuts down on installation and commissioning times greatly!
