Help me connect arduino with HMI Weintek!

Now, i have HMI Weintek MT6070iP. But when i connect HMi with arduino by Modbus RTU then display show"PLC no response".
Please help me.
I follow manual:

File is my HMI project!

New folder.zip (361 KB)

I refuse to go through the hassle of downloading and unzipping a file just to help you.

Learn to post code.

Hi!
I did it :slight_smile: I use Modbus RTU protocol over RS485 and it work correctly! (HMI master <-> Uno slave)

When I back home, I will write you more about this, if you want :slight_smile:

In future I want to do Smart home using FATEK PLC + Weintek HMI + arduino modules. Everything communicated over this protocol :slight_smile:

Hi, Im trying to do the same but I dont know how I have to proceed because is my first time using Weintek HMI and arduino, if you could upload your project to guide me, I would greatly appreciate it.

Thank you so much

Is anyone Make it to Communicate Arduino Slave with Weintek hmi?
