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!
hola a conseguido hacerlo funcionar con arduino mega?? a, un coHol
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
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
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
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, 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.
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.
Is there any way to choose serial3 output for those with a mega/controllino board?
If I want to change serial port to Tx1, Rx1 or pin 19 and 18 on Arduino Mega other than default port then how can it be done?
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???
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.
@@WeintekUSATeam.0 oooo right right thanks
Hi can you write simple connection code between arduino rs485 to plc fx3u ?? Thank you
Can we do it using an ethernet shield using an ethernet cable to any iP weintek series.
I tried code as like you but I'm getting error at slave.SetBaud stage as it is asking me to fill 2 unsigned char , word and hardware serial and I don't know what to type in the bracket. 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?
The libraries are not complete and compiled, can you send a new link please
Thanks for your video..can we use rs232 communication..from hmi to arduino.?without conversion board rs485
Hi Uge,
For your application you will likely need an RS232 to TTL adapter or shield in order to communicate over an RS232 interface.
Thanks for the great video. Can you please add the links for the example projects?
Hi there,
We've placed links for both the example project and the libraries within the description.
Great
Help me to compile this code.my arduino ide is 2.2
Did you use tags or registers for communication. Because you didn't show it in video.
Hi Arbaz,
Within this project, we reference Modbus registers within the Arduino while building the HMI project.
how to acces (write and read) data value ? is there example code?
Hi Eng,
We have placed a download link for this application within the description.
not working, this example you show on you movie doesn't exist in arduino modbus library
Cannot upload your code to my device, i have this error message in Arduino IDE " exit status 1
no matching function for call to 'modbusSlave::setBaud(int) "
Hello,
Did you retrieve this code from the Github link in the description? If so, were you able to resolve this issue?
can i connect this system modbus with MT8050i HMI..???
Hi Mostafa,
The mT8050iE supports the "Modbus RTU, RTU over TCP" driver as well. You can certainly use this HMI within a similar application.
Cannot download the Arduino library
I forgot to mention that no icons appear on the HMI
is it worth reading a 32 bit register?
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.
@@WeintekUSATeam.0 hello
How can I read a 32-bit register?
Good morning
I repeated the example to the letter.
I use an MP8071iP.
I get the error message: "Device No Response".
Why this mistake?
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.
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.
@@rovivo that right! thank for your comment!
@@rovivo I've changed the display connection setting to 8N1 but still get error message: "device no response", and i dont understand about station nr.. can u help me please ?
Yellow light did not light up, red and green light does.
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
