I understand the title seems too broad but it's a bit specific and I'm totally new to the communication stuff, so please bare with me. If the question is too broad, please provide some suitable links that I can look upon.
Now I'm given a simulator pyModSlave and a USB driver, that has two output pins.
and an ESP32 .
Interface ESP32 with RS485 annd run ModBus library of Arduino IDE with RS485.
- What is the difference between RS-485 and MODBUS?
- How does data get transmitted in this type of system? For example, say I've a temperature sensor, that gives out data in RS-485. What does this mean? All I know about transmitting data is as a binary number as 1s and 0s. What does MODBUS do in all this?
