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.
