Overview

The devices connected to a Modbus RTU bus communicate using a half-duplex RS485 link with the following standard parameters:

• ModBus RTU communication protocol
• Settable communication parameters
• Default communication parameters:

o Baud rate: 19200

o Data bit: 8

o Stop bit: 1

o Parity: Even

A single frame of data is called PDU and in RS485 configuration its maximum size is 253 bytes (256 – server address - CRC).

Every connected device must manage its own RS485 transceiver, enabling and disabling it in order to achieve the correct data exchange over the wire without errors and conflicts.
