Siemens S7 1200 Modbus TCP/IP Communication with Arduino

Hello!

Nice video. I have a problem I am using the files you uploaded. But I have a problem with the block of send data to arduino. I don't saw the number reflected on the serial port of arduino, only the number 1. Do you know which is the problem?

Really nice tutorial, thanks a lot for your time. I have question, why sometimes we have to add 4000 or 3000 (depend on the type of register) to the server data address, and sometimes not, for exp. you did not add, but I saw on the few turotials people added. Does that depand on the modbus library version?

Hello, thanks for your video. Im trying to make it work on a Mega but the program get stuck in the mb.config line. I have tried almost everything I found on the internet but it wont work. Can you give me some advices please? Thank you.

wish arduino library we use ?

why do i download the modbus library file and add it via IDE, it says the file is not valid

groso

thank you so much,!!

hello, there are some esp32 modules that have ethernet port. Can we use that port to modbus communication with plc and then upload data to the internet with help of the esp32's ability to connect wifi.?

ModbusIP_ENC28J60, where to find this library?

Hello Sir, Thanks for your Video, I have a question about the connect PLC S71200 with Arduino. How to connect 2 Arduino with PLC S71200 using Modbus TCP/IP? Please Answer my disturbance..

Do we need a plc hardware to accomplish this?

When i start the script for esp (with if (c=4) (send 40 for reg1 for exemple and if c=5 send 30 for regs1 ) i have the same value in plc data block all time ( with c=5 i have 40 also ) what the prblm!!

Can I use plc emulator?

Any chance you did this with a M340?? ahah. still trying to figure out how to send data to Arduino using a M340? any help is welcome. Thank you.

Good tutorial,
I can read from Arduino, but when i send data to the Arduino the serial monitor gives only 3 times 1 like is set in the program from the Arduino.
I think something is not right with the program.
Hopefully you can help me with this issue.

mb.addHreg(reg5_HREG, 1);
mb.addHreg(reg6_HREG, 1);
mb.addHreg(reg7_HREG, 1);

The upper 3 lines are a little strange.
The three 1 is what i see in the serial monitor, and not the values what i put into the send array from my siemens.

its the first time that i work with the arduino thus maybe i be wrong.

Thanks in advance
Frans

modbus.h library need

please give same concept with esp8266 with siemens plc

can I sent also string? thanks

Thank you very much.

Hello Sir! Can you provide some wiring information about ENC28J60 for arduino mega? I searched everywhere and found nothing :(

Thanks for the video. I just want to know if such a communication can be established using a virtual plc ( Plcsim or Plcsim Advanced) instead of a real physical S7-1200.

Hello sir, i want to communicate s7 1500 as Client with s7 200 smart as server over Modbus TCP/IP
There is lack of documentation and examples of 200 smart on internet n industry mall can u pls help me in the communication between both the plc

Does anybody have problem with ping Arduino IP address? I upload program without any problem, but I can't ping Arduino. I managed IP address to be in same subnet. Any tips and help? Tnx.

Alguém sabe como se faz isso, só que com um PLC Omron ?

Hi, thanks for video. Can you say how you physically connect PLC and arduino? Did you use only RJ45 between these two devices?

Does that work with the basic Arduino AG ETHERNET SHIELD 2 ?

Hello sir , i don’t know that what is the function of switchPin13 ?

Hello sir... can you help me set up ip address and Mac of arduino shield... I did it follow you but It don’t run and arduino cant sent data to plc :( ...i hope you can help me !

hello, I downloaded your files and only change my IP, but the blocks are both in error, can you help me understand why? thanks

Hey, buddy! Can you help me, please? I'm following the example of your video, but when I insert in Step 7 the second block Modbus Client and Do the settings to write in arduino nothing happens. My second Modbus communication block never works... The "Done" status of the block always becomes false.... Would you have any tips to give me? I'm using an S71200 with an Arduino and a shild ethernet.

Can you make the same video with a siemens Logo 8 ?
