pyModbusTCP - the easy way to a Modbus TCP server with Python

nice! good for me

someone can help me, i am trying connect the ELIPSE E3 Client - Modbus Server with python.

Dear Sir,
1) kindly share the sample code for schneider EM6400NG Smart Meter, i have tried so many ways still i got nothing, myself use pymodbus library and payload library to decode the output but no response, (Error: Attribute has no registers). kindly help me sir (Modbus RTU over TCP Client)

Wow what is up with your line numbers? 😅

thanks a lot its very usefull information

Perfect tutorial, precise and concrete explanation.

A note to anyone trying this now. The class method DataBank is deprecated and you should use the attribute data_bank of the server object instead. Also the set_words and get_words is also deprecated and has been replaced by set/get_holding_registers.

server = ModbusServer()
server.data_bank.set_holding_registers(0,[5])

Good evening! Please, when I put it to run, "none" appears. What is happening? thank you.

Fantastic video. Exactly what I needed

Amazing, thank you.

I needed to implement a simple modbus server for developing options but couldn't make it with pymodbus only, this modbusTCP is amazing, thank you very much

I am glad your doing it the python way also. I love C but some things are just easier and quicker with python.

Hello thank you for the video.. When I try to execute python server code server immediately shutdowning. The code is exactly same of your code

Wow just amazing dude! Great work keep it up!

How do you setup a client as a VM?

Very good tutorial, thank you!

Thank you so much, I discovered your channel recently and I am learning so much from your content, keep going

how you installed?? what program i have to use?

Hwo to capture the modbus by wireshark?

I'm a newbie in python, only prior experience is vanilla arduino IDE.. I tried various other tutorials with no luck, this one worked! I'm trying to replicate a modbus server/client I made with an arduino. This video really helped me thank you.

hey i have a question, you didn't mention the exception is raised when you press ctlr c, but why does it work like that , is it default.
and how can I raise exceptions with particular conditions.

Good evening, very good your explanation, I am starting to carry out a project with pyModbusTCP and you have helped me a lot with this video. I have a question, what would be the next step to connect my PLC as a client and that he is the one that passes the records to my server, in addition to being able to save those records later in a database, thank you very much in advance

A question, if there is a linux kernel driver for a particular device and I want to write a userspace program to talk with that device, can I simply call the existing kernel driver and use that or should I write a userspace driver from scratch?

Thank you ! Greetings from berlin ❤️

It saved a lot of time for me. thanks for sharing

Damn , Python is gorgeous !

Thanks, works like a charm - I could easy simulate a device which is under development with a few lines of code

Awesome video !! Helps a lot

Hello! I am using this library, and I observed a problem, the library doesn't work with negative numbers!
I noticed that the -1 value is read as 65535, the function to read a holding register is supposing that is an unsigned int with 16 bits. To correct and read the correct negative value I transform the bit using the complement of two.

i cant get my client to see any server devices (i just plugged a device into my client through ethernet and used the ip address from the connection).

Thats awesome! Is there also a video of serial ASCII communication? Speaking of using an Modbus RS485 connection.

Hey, ich habe ein Problem eventuell hast du einen Rat für mich. Mein Server fährt direkt wieder herunter ohne das ich ihn per Eingabe ausschalte. Anscheinend stimmt etwas mit der continue Anweisung nicht...:( komme aber nicht darauf, es sollte eig alles passen

Good video and simple explanation...
I need to read register values from a meter register. The meter I am using is "MFM383A" Selec meter which is connected to my PC through an ATC converter using RJ45. Is it possible for me to read the register values of the meter using this method. Please help.

how get unit_id of clients

hi sir i'm very new to this python-modbustcp thing. first, thankyou for the explanation! but i have a question, when i try to start the server with the instruction you give, my server is offline.. again n again.. (im using windows pc as client) i also connect my plc with ethernet cable directly to my laptop. do u have any idea about this? thankyou in advance!

I really needed this! thank you so much! very easy to understand and do. I setup mine between two Raspberry Pi's and controlled a server motor via modbus... Thanks again.

Hello! Thanks a lot for your insightful video. I would like to ask you something: I haven´t been able to find the complete documentation for pyModbusTCP. I'm interested in exploring which other functions does Databank offer. Could you please indicate me where did you find that info?

Thanks again! Viele Grüsse!

Hi,Great video!!
I had a question. Will this work as a simulation of communicating with a PLC by imagining the PLC as the server and my laptop( sending values) as the client?

Thank you very much for posting this!

Hi, will you make more videos on modbus TCP in Python? I have a Dryve D1 controller for a linear axis and it can be controlled via modbus tcp, but i have no experience in that matter, so at the moment i am controlling the axis via webinterface (comes with the controller). Or can you suggest any literature where i can get up to speed on modbus TCP to be able to use it with python scripts?

Great video, been looking for something like this! Keep up the good work!

Is different module from pymodbus? And is this module compatible with python3?

It is brilliant explanation!
Thank you for posting this!
