Thanks Real Pars, as always, you guys describe complicated technical issues in a very simple and understandable language. I'm a huge fan of your videos.
Hey! Thanks a lot for your kind compliment! We are always extremely happy to hear such positive feedback! If you ever have any questions, feel free to reach out to us. Happy learning!
I feel both great joy and sadness watching these videos and it’s conflicting. Great joy in that I learn sooo much than in my own job in Operations, Process & Automation Controls. Great sadness and it saddens me to admit it here also in that I don’t learn this much in my own job in Automations dealing with all these components, devices, protocols and plc’s and that saddens me greatly. I started my career as a Operational & Mechanical Technician in Operations at Utility and Power Plants. I now more work in Field Service, Equipment Commissioning, Plant Startups and Automations. The engineers when they even try to explain stuff are never close to this clear in explaining anything at a simple level either. As my own company also don’t believe in training or sending anyone to training. Sadness to me. But great joy watching and learning to fill in the gaps in my knowledge watching these videos. Every video I see I can relate to something done in my job or where I wasn’t clear in how something worked. The easy explanations here fills in my knowledge greatly and with great joy. I can’t say just how much I enjoy watching the videos here and know it’s directly affecting my job and what I know as well when I look at the devices, components, plcs etc.

Thanks to REALPARS. This video is a high level and precisely explains the HART protocol. I will help to share in my Linkedin network and hope engineers will have a good understanding of the HART protocol and able to choose the correct instrument if they looking to collect the diagnostic data preparing for predictive maintenance.
RealPars. Appreciated for your offer. I am actually just completed introduce a good size of a instrument diagnostic system into my company and gained massive success. Am currently preparing another one for another project, I hope repeat my success but further embedded into the New Way of Working for my colleagues. I potentially having some question about the DD compatibility questions if you have in depth knowledge about that.
Hi Rohit! Thanks a lot for your kind compliment! We are always extremely happy to hear such positive feedback! If you ever have any questions, feel free to reach out to us. Happy learning!
I liked your video, you have made it in a concise and clear way that it is a HART protocol, its history and even how analog sensors work, the best part was when you explained the ASFK and gave an example of the telephone line.
Importants facts like the increase Plant Availability, Reduce Maintenance Costs and Improve regulatory compliance. Excellent work!!!!I will like more videos with good information about the protocols in the industry. Greetings from Ecuador!!
My god you are amazing at teaching. I was wondering why you were talking about bell 202 modem standard, until you linked that same concept to HART and then boom, I understood! Thank you for the video!
Cool video! You have 5 modules: 1) A power supply 2) CPU315-2 DP Power Supply 1P 6ES7 315-2AG10-0AB0 3) 6ES7331-7TF01-0AB0 | HART Analog Input Module 4) What is this module and it's function? 5) What is this module and it's function? On module 2) Does RS 232 connect to the PC with a USB and a HART modem?
The fourth and fifth modules are analog input modules just like module 3. They were added just to show that a CPU315-2 rack can have multiple I/O modules. The programming terminal is connected to the CPU using either a Profibus-DP connection or an MPI connection. These are both serial links that require a special modem or PCI card at the computer end. A HART modem is used to communicate with a HART device in order to configure the sensor. This connection is external to the PLC hardware setup.
Excellent video, really interesting known the protocol and also the history, the parallel view of the "bell 202" with the HART Protocol make clear the explanation!

Remember, in a power outage, an analog phone will keep working as it has its own power supply. good to have a backup 'dial' phone without the battery. you can still call emergency, do not need batteries or power.
I've no words to thank you for your these useful videos. Plz upload some videos on control valves , positioners, its calibration, commissioning and trouble shooting as well
Great explanatory video, it helps me a lot to understand where HART communication comes from and actually gives me an idea of support and maintenance implementations in the industrial area.
I wish to have a clarification, how to connect non-hart field transmitter having output 4-20 mA with HART communication network or HART enables PLC? Whether i can go with adapter to make my field device into HART enabled?
A HART-enabled transmitter still requires a 2-wire connection at the Analog I/O card. PLC cards typically allow selection of HART mode and non-HART mode (i.e., HART enabled or disabled) for HART-enabled analog cards. If you have a transmitter capable of HART communication, you can choose to use the HART functionality or not, but enabling or disabling HART communication at the I/O card. Leaving the I/O channel with HART disabled allows traditional 4-20ma loop-powered signals to be sensed at the analog input card. You should refer to the manufacturer's I/O card documentation for verification of this feature. An analog or digital transmitter cannot be converted to a HART transmitter with an adapter. A transmitter must be manufactured as a HART device.
Dear, please make a video on why only 4-20mA current loop and 0 to 10VDC are bacame as a instrumentation signal what is the practical reason and how n from where these values are derived .
Not quite. If you recall, a rectified dc voltage is not quite flat, it has its peaks and troughs like ac voltage, but they average out to a dc voltage above zero. Rewatch at around 12 minutes.
Great video, i would like to know which PLC are you using... and if you can use the HART protocole with any Siemens PLC (more specifically with the S7-1200 and S7-300).
The video did not specify the PLC model since it is showing how HART is used in a universal, generic way. For use with an S7-1200 or S7-1500, you just need to make sure that your analog input card is one that supports HART protocol. There are HART-enabled AI cards (and AO cards) available for most all of the Siemens S7 PLC models.
1200 Hz. The graphic is correct. The narration was not. I believe someone else pointed this out last year, but it is worth repeating again. Thank you for your comment.
HART protocol is based on the older Bell 202 protocol. In this node-based protocol, only Master nodes can send data requests. Sensors (nodes) do not have the facilities to generate interrupts or initiate communication.
Hi there, Thank you for your question, and our apologies for the delay in our response. To ensure a reliable engineering setup, here are a few key steps I would recommend: 1. Select the Right Cable: Begin by choosing the recommended cable for your specific application. It should invariably be a shielded cable. 2. Conduit for Long Runs: If you have an extended cable run, it's advisable to encase the cable within a conduit. This practice is typically endorsed by the HART device manufacturer. 3. EMF Signal Isolation: For optimal performance and minimal electromagnetic interference (EMF), adhere to the distance recommendations outlined in the data sheet. Maintaining adequate separation from EMF sources is crucial. Following these steps is standard procedure for the installation of HART or any 4-20mA signals, and it helps to minimize the risk of EMF interference. Happy learning!
One question with the Profibus communication network, can you send analog data? If it is not possible then the profibus cannot regulate the process, therefore it only sends information from the sensor to the plc but does not regulate the process, is this correct?
Hi there, Thank you for your question, great one! Profibus communication converts all the signals in the communication protocol needed and transmits them, then converts them back to the receiving end. The PLC regulates the process as needed. Happy learning!
Thanks, very informative. Question: Can an Ultrasonic flow sensor with HART output been connected to an analogue input card that does not support hart, if only the 4-20 mA signal is used?
Yes, but the HART capability will not be available to the control system. However, the HART signal is still being communicated, so using a handheld or PC-based interface can still make use of the HART signal. Many plants use this approach. The advantage of using a HART-enabled PLC or DCS analog input card is that you will have the secondary PV, SV, and TV all available to the control system, as well as the primary PV and diagnostic info about the device.
Is it possible to read the process values digitally, i.e. skipping the A/D in the PLC I/O module, using HART? (Meaning the 4-20 mA is not used for anything really)
Yes. When HART is enabled, it is used to collect the PV data. The 4-20ma loop current is used to power the device, even though the analog signal is not used to develop the PV value.

Dear, please make a video on why only 4-20mA current loop and 0 to 10VDC are bacame as a instrumentation signal what is the practical reason and how n from where these values are derived .
Hi Hara,
Thanks for sharing your suggestion with us! I have sent this over to our course developers.
Happy learning!
So since the Hart signal is a frequency wave, is it AC voltage riding on the DC 4-20mA?
Not quite. If you recall, a rectified dc voltage is not quite flat, it has its peaks and troughs like ac voltage, but they average out to a dc voltage above zero. Rewatch at around 12 minutes.
Such a good video, i liked how did you explain this useful tool.
Thank you, Kevin! We appreciate that
Great video, i would like to know which PLC are you using... and if you can use the HART protocole with any Siemens PLC (more specifically with the S7-1200 and S7-300).

Muy interesante y claro, es un protocolo super útil para el mundo de los programadores.
Gracias, David!
never measured the output of emf on devices, good reminder video, takes me back to GM days..
Is there any way to have sensors send interrupts to masters? or can sensors only respond once told by the master?
HART protocol is based on the older Bell 202 protocol. In this node-based protocol, only Master nodes can send data requests. Sensors (nodes) do not have the facilities to generate interrupts or initiate communication.
how are HART sensors shielded from unwanted outside emf/radio waves/purposeful fault creation
Hi there,
Thank you for your question, and our apologies for the delay in our response.
To ensure a reliable engineering setup, here are a few key steps I would recommend:
1. Select the Right Cable: Begin by choosing the recommended cable for your specific application. It should invariably be a shielded cable.
