RS485, also known as TIA/EIA-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. It enables the creation of robust, multi-point networks capable of long-distance communication up to 4000 feet (about 1.2 kilometers) and supports data transmission rates up to 10 Mbps. RS485 is widely used for its ability to connect multiple devices over a single pair of wires, making it ideal for industrial environments, building automation, and networked communication in complex systems. Its differential signaling helps to resist electromagnetic interference, ensuring reliable data transmission even in challenging conditions.
I would like to monitor the status of my ABB Aurora inverter (formerly Power One now Fimer). So with a WeMos D1 mini I create a monitoring station with web interface, notifications and more.
Now we are going to wire our Arduino to the Inverter.
Here my library that implements the complete communication protocol of ABB (ex PowerOne) Aurora Inverter suitable with Arduino, esp8266 and esp32.

Here we will explore the infrastructure of the project.
RS-485 work as a broadcast; when you send a message, all devices connected to the wire receive that, so peoples use It is better to implement a lot of protocol to send a message to a specified device or a broadcast address. This article uses regular communication from two devices in a very simple way.
