Just realized that I have some weintek hmi sitting in my attic for 4yrs now... and that would be huge to make it work with arduino mega. Thanks for this video. It is funny how many things it is possible to do with those tiny cheap arduinos!

I csnt find any resources on making Arduino communicate tcp/ip.

Hi,thanks for this useful video. Can you provide link to the video reading integer from HMI with arduino, you mentioned it in the last part of this video. PS I think i found it, is the robot arm video

Hi, I am using Easybuilder 8000 for MT6070ip, and connecting with arduino uno. I am following the same process as in this video but it's not'working out. Moreover, there is no option for "MODbus RTU, RTU over TCP" in easybuilder 8000, that's why I am selecting "MODbus RTU". Need your help.

Can i read data in a Elevator system's MODbus or Canbus so that i can find out the floor number shown in the display using arduino? Please help

@rickdalton7907 Год назад

The MAX485 module that you connected at 3:17 is not the same as you have in the picture at 0:48, which has DE and RE pins. The only modules I can find are the type you show at 0:48. Can you share where you bought the module that you used in the project? ... The one we see at 3:17.

@user-pb6pk7mv2k 2 года назад

I use RS485 connector (in video 00:40) to connect it to arduino there are 4 pins: di(tx) ,de ,re ,ro(rx) and vcc ,gnd . Where to connect de,re ? Doesn't work without them

Hi thanks for the tutorial , please tell me how do I change the serial on the modbus library . I bought a plc arduino mega that has rs 485 on pin DI 14, RO 15, RE 11, DE 46 can you help me? Thanks in advance

Thanks for the great video. Can you please add the links for the example projects?

@WeintekUSATeam.0 3 года назад

Hi there, We've placed links for both the example project and the libraries within the description.

@ibrahimaliabbasi5188 2 года назад

thanks for clear explanation. Just one thing. What's the purpose of that white cable attached to your HMI besides RS-485 adapter at 8:50???

@WeintekUSATeam.0 2 года назад

Hi Ibrahim, The white cable at 8:50 is an Ethernet cable that was connected to our PC. It allowed us to monitor and control the HMI remotely.

Thanks for your video..can we use rs232 communication..from hmi to arduino.?without conversion board rs485

@WeintekUSATeam.0 2 года назад

Hi Uge, For your application you will likely need an RS232 to TTL adapter or shield in order to communicate over an RS232 interface.

@user-zj2wm1hy4q 4 месяца назад

Can we do it using an ethernet shield using an ethernet cable to any iP weintek series.

@pdelettronica 3 года назад

I forgot to mention that no icons appear on the HMI

@arbazansari7647 2 года назад

Did you use tags or registers for communication. Because you didn't show it in video.

@WeintekUSATeam.0 2 года назад

Hi Arbaz, Within this project, we reference Modbus registers within the Arduino while building the HMI project.

Could you please help me in this part as I'm using same RS485 to TTL converter what you have used so that it will be helpful in my project?

Good morning I repeated the example to the letter. I use an MP8071iP. I get the error message: "Device No Response". Why this mistake?

@WeintekUSATeam.0 3 года назад

Hi Davide, In order to assist you, we will need more information about how you've designed your project. Please send an email to support@weintekusa.com with a brief description of this issue and your HMI's serial number.

@rovivo 3 года назад

There is a mistake in the video by the Display connection settings. The Arduino library in the description is hard set to 8N1. (Line 22 in modbusSlave.cpp "// defaults to 8-bit, no parity, 1 stop bit") So set the Display connection settings to 8N1 and check the station nr. of the display, it must match the number in the arduino code line 15.

@WeintekUSATeam.0 Год назад

Hi Mostafa, The mT8050iE supports the "Modbus RTU, RTU over TCP" driver as well. You can certainly use this HMI within a similar application.

is it worth reading a 32 bit register?

@WeintekUSATeam.0 2 года назад

Hello Robin, If the data that you are trying to read is held within a 32-Bit register (Example: The number 1,000,000) then it will be necessary to read a 32-Bit register.

Sir i used your libraray and code but in compiling too many errors. Like wprogram.h not found. I rectify this error with replacing wprogram.h with arduino.h and now i am receving eeprom.h not found
