What is Modbus Communication Protocol? | Basics of Modbus TCP/IP and Modbus RTU

[@kencompton33]

This guy really makes it easy to understand Modbus and it’s configurations. Breaks it all down into simple terms we can all comprehend. This is by far the best video on the topic I have found. Thank you for helping us all out and greatly appreciate you sharing this!

[@engrnoumanali8005]

After a long time i cleared my confusion of Modbus

[@shyamsundram3430]

after long time clearly understand modbus protocol. thanx sir

[@emmanuelodoom3354]

Well explained video,however Client (Master): The client initiates communication by sending requests to the server. It reads and writes data by sending Modbus function codes and data frame requests. The client is typically a device like a SCADA system, PLC, or HMI that needs data from field devices or wants to control them. Server (Slave): The server is a device that responds to the client’s requests. It usually contains the data or the registers the client needs. Devices such as sensors, actuators, and PLCs are often servers in a Modbus TCP network. They hold registers or data that are read or written by the client. In this communication model, the client controls the communication by requesting data, while the server responds to those requests without initiating communication.So I believe per your presentation ,the PLC should be client requesting for data from field devices(Server) which have data of interest

I will wait for next video.Thanks this video very helpful for us.

[@insaafarmy786]

just wow wow wow excellent thank you for this video

[@WeconTechnology]

very good basic video for modbus.

[@girishrachh5843]

It is well explained difference

[@ardentdfender4116]

Another well explained video. It never goes wrong when a video is very helpful in understanding of a concept or protocol being explained in a simple to understand way to grasp the concept in basic understanding and you did that very well here. I understand what Modbus is, but i'll admit i'm also not closed minded at all in that someone else can explain it in a different way and i get a whole different understanding in my mind core or what I thought I understand, now understanding it much better. Such is learning.

[@mixme8655]

new subsciber always watching your videos ver interesting

[@muhammadnabilkhoirulrahman1476]

In several references, they said that In Modbus TCP/IP, the server is the field devices that provide data after the PLC (client) sends a command. This is the opposite of what you described. Can you explain this more? Thank you so much.

[@biswajitkhilar4042]

Very informative . I want to know about the modubus repeater . What is that device ?

[@mdmahtabalam925]

Holding registers or analog outputs that are for Modbus master or slave devices?

[@saiyadsakibali9640]

Mashallah

[@killekaryash2099]

Great work sir.. plz make videos on whole industrial networks like device net,profibus etc .plzz

[@ITandAutomationAcademy]

Ok sure

[@Callisto1969]

Great explanation - thanks very much! I know nothing about communications protocols, but this video has helped to answer some basic questions and give me a basic understanding.

[@munmunkumar9546]

Thanking you. Can you please explain Internet cable and ethernet cable

[@ITandAutomationAcademy]

Sure will create one in future

Many thanks.

If have only one of cootroller it mean not need to use protocal? It cas use only 4-20 mA signal? Please explain to me 😮

[@devendrabhagat2480]

Nice sir, how to connect modbus rs485 to three cables

[@srivasthavavenkatesh960]

How can you differentiate Profibus and ModBus? Since Profibus also follows Rs-485

[@engineerarsalan1832]

With profibus you can only connect 125 devices in segment while with modbus you are able to connect almost 245 devices at a time. -profibus and modbus both follow serial communication protocol. - both are two wired - modbus rtu and profibus dp is master slave. -both are asynchronous -baud rate of profibus start from 9.6kbps to 12 Mbps. Varies with length or use repeater.

modbus RTU is similar to profibus protocol?

[@Engr_Moznu_Sheikh]

Where are you from??

[@nadunipramudika7159]

[@muhalfiya]

Can this protocol send floating data?

[@rajkrishna336]

Yes

[@muhalfiya]

What Function Code we use for floating data?

[@shreyasj6437]

@@muhalfiya Function code is 16. Floating values are 32 bit. Modbus supports 16-bit word registers. So u need 2 16-bit registers

Please explain noman Sahab.

Kind sir is it good to learn deep learning for automation? I must learn deep learning for master degree in automation but I couldn't find a relevant subject on automation Is there any reference for relation between deep learning and automation Can you give me your website for the courses you make?

[@jon0-niel910]

Modbus between master and slave actually isn't an ethernet cabling system its a two wire system
