Use the RS485 properties to configure the baud rate for communication and control pin connections of the RS485 network.
You can set these parameters to configure the RS485 properties.
Select the type of serial module or port that the block will use for MODBUS® communication.
Set the baud rate of the serial port on the Arduino® hardware for the RS485 serial communication.
Select the data frame configuration for the RS485 MODBUS communication blocks. The first digit indicates the number of bits in each data packet. The second digit indicates the parity bits present in the data packet. The last digit indicates the number of stop bits in each data packet. For example,
SERIAL_8N1 indicates 8-bit data
communication with no parity bits and one stop bit
SERIAL_5E1 indicates 5-bit data
communication with even parity bits and one stop bit
SERIAL_6O2 indicates 6-bit data
communication with odd parity bits and two stop bits
