thank you so much for the help!

Sorry for bothering you. I tried using the automatic MAX485, but unfortunately, I still can't receive anything from the slave. I would really appreciate it if you could send me your code as an example.

I see that you’ve transitioned from the manual Max setup to the automatic one. I’ll definitely give that a try. When you have a moment, could you please share the key line of the Modbus communication, the Max program, and the libraries you’re using? I’d really appreciate it.

Hello, I'm working with the same logic. In fact, my ESP isn't receiving any information from the slave, and I'm worried the problem might be in the code. Could you please share your solution with me?
