Siemens S7-1200 to Arduino Modbus TCP/IP Communications Part 3.

Thanks for this great tutorial. Are you sure about the the terminology you explained in the beginning of the video? I think Modbus server and Modbus Master are almost the same thing. It is correct for Modbus client and Modbus slave. But you mentioned something different. Could you check that please?

Have you ever used the library Settimino to make a conection Arduino - PLC?
Great tutorial btw

can you show me how to code when i have two more potentiometer, please help me

Wait whut, slave = server and master = client. Who thought that was a good naming scheme.

Great tutorial

thanks sir for the nice video.
how do i configure my Arduino as master in tia potal?
thanks

Sir, can I connect arduino shield straight to my laptop,So that it acts as the real plc? I don't have enough money to buy s7-1200.

I’m hoping this works over WiFi connection between S7 and Arduino?

I have an Arduino Braccio shield on top of a Uno WiFi R2, adding the Ethernet shield causes the Braccio (robot arm) to fail.

do have one on esp32 serial2 modbus rtu rs485 19200n1 master read input-registers 30001 30002 from slave-1 digital panel-meter-modbus then display the values serial monitor?
great modbus video, thank you 🙂

Hello sir, can you please help me on how to communicate the laptop and arduino using modbus protocol.

hello please can you help me about communication between esp 32 arduino and interface HMI

I have tried to port this code to the rp2040. The rp2040 uses ‘C’ code and I needed to modify the headers. Unfortunately I was not able to adapt the code.

I wonder if anyone else has tried to port the Modbus tcp code to stm32 or rp2040 (I feel I’ve that they are both arm cortex M0).

would be really helpful if you would give us the link for the libraries you downloaded in Arduino IDE

Thanks for the tutorial, im using ESP32 instead of arduino with ethernet shield. Thank you so much

Hi, at home my code is working but when I do a ping test, I don't have any signal you have any idea?

Hello sir, first i would like to thank you for all your videos.
If you don't mind i have a question for you: actually i'm working on a project where i need to use Tia Portal as an HMI (with an S7-1200 which is already done and works for me), but the problem is i that can't connect my PLC directly to my system, so i have to use an Arduino between the PLC and my system. For that, is there a way to make the connection you already made between Aduino and PLC but these time conversly? what i mean is i need to send data from PLC (specifically my HMI) to my Arduino.
And thank you again for your time.

Hi! Today, I've done a prototype to measure high currents (80kA) through a shunt and an external ADC, then the Arduino send that to a PLC 1200. Thanks to your (great) tutorial, I've done that in few hours.
Thank you very much!
