Hello Everyone,

I'm interested in learning the Modbus communication protocol by conducting practical experiments. To get started, I'd like to know which parts would you recommended for Modbus communication.

I currently have a PIC18F45K80 microcontroller and two pairs of TTL to RS485 converters. Can I use these RS485 converters for Modbus communication, or do you recommend other components?

I don't see why not. What is the PIC18F45K80 going to communicate with via Modbus?. What is the model of the TTL to RS485 converter so we can make an informed determination.

In Modbus communication setup with the PIC18F45K80 microcontroller and RS485 converters, the sender and receiver can be defined as follows:

Sender:
The PIC18F45K80 microcontroller is typically the sender in this context. It sends Modbus requests to the device we want to communicate with.

Receiver:
The Modbus device (e.g., another microcontroller .) is the receiver. It receives the Modbus requests sent by the PIC18F45K80 and responds accordingly.

 

What modbus software are you using for the controllers for master and slave functions?
