What type of ethernet switch did you use?

thank you very much

very instructive tutorial, thanks a lot

MB_Unit_ID was very important to me 🙏 I swear such simple info doesnt exist on tia forums or anywhere else on youtube.. wtf

How do you now witch port is free? Or witch one to use?

hello sir, i did everytihng same but connection not establish. how can i find the way

thanks for this great video :))

Although this tutorial unintentionally hides a lot of details about Ethernet for the uninitiated, that doesn't stop it from being an excellent tutorial.

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?

Hi, that is helpful. thank you.

My friend , thank you for the video. Everything was clear until 6:28 ( you work in DB2, ok. Then you jump to arduino to see the IP, and when you come back to DB2 THERE A LOT OF NEW VALUES CAME FROM NOWHERE ( I am beginner in TIA). So at 6:28 I see DB2 with some values, but 6:33 the same DB2 has 16739101 new values. How? From where ? I am desperate ….

Can't see anything clearly on your screen, which makes this video less useful.

so connect both wires to the same port the negative and positive of sensor both to the 1M port

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

Thank you for your video But i have issue. I use a IP for Ethenet Shield and use mac [ ] same you and make code same you. However Status of MB_CLIENT show is 16#7002. Disconnect Arduino with PLC You have any solve for me. Thank you so much

great

groso

thank you so much,!!

When I connect TCP IP device just to SocketTest v 3.0.0, I receive string [1]T000000000003 in SocketTest as Client Then I connect separately PLC to SocketTest v 3.0.0. and I receive also string [1]T000000000003 on PLC Client and SocketTest as Server. But when I connect just PLC and TCP IP server device to read string on PLC, I receive in PLC on TCON block STATUS 16#7002 »Connection is being established (REQ irrelevant).« But connection is not established. TCP IP server device is connected directly to PLC. What could block the connection?

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.?

Thanks for the video. Really good. Is there any way to conect the PLC to any Python aplication? thanks

Hi sir, can I use your code as a server ? I have a application need send a string from PLC (Server) to a app (Client) . Thank you !

ModbusIP_ENC28J60, where to find this library?

Thanks for the video

Hello and thanks for your helpful video. When I click on the link for the tool, it doesn't lead to a link for downloading or buying the software. Is there any other link you can share here to download? Thanks a lot.

when you enabled clock you must install that page if you dont install and fast make main your clock not work. sorry for my english

I had to stop/start the CPU, works great, thank you.

is it possible to implement ascii over tcpip using this method? do you have any video on that

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?

Thank you for your work and video!

thanks a lot for the well illustrated and explained video, really appreciated. what is the name of the modbus tool i need to download it

thanks ^^☺☺☺

Awesome

Hi bro, my english not well, can you tell me on s7 1200, how many blocks TCP Client can we use, thank so much

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?

Hi sir thank you for sharing tutorial. I have one question. Can i use this system for multiple program?

The firewall of my private network has blocking the communication, but i can connect the modbus poll and modscan with the modbus tool when my firewall is on, but not my plc, thx for the video!

After receiving string, Data receive had additional 2 characters $R and $L. How can i fix it, sir ?

Is it nesessary to turn off window firewall before making connection, Sir?. I downloaded ur project but it didn't work

Hello Bro. I have followed your step but when i pressed "listening button", I couldn't have connection. A message pop up "cannot assign requested address jvm_bind". Many thanks ^^

And if I want set my computer as client and the Siemens CPU 1200 as server how I can configurate?

Thank you for your sharing. it is great information.

Excellent tutorial. Side note... If you are having trouble getting a response from the SocketTest app, disable your firewall.

What are the application in realtime based on that , Siemens to modbus tcp/ip to Windowns

Hi, why do you pronounce PLCSIM as "ploksim" instead of "pee-el-see-sim" ? Did you use a "speaking-machine" software for narration?

I cant get connection. Do you have any idea why? Same adress and port on the socket test and tcon and it still it does not connect. Could you help me?
