Configures the baudrate of the Modbus communication. The following are available:
▪
1200 bits/s
▪
2400 bits/s
▪
4800 bits/s
▪
9600 bits/s
▪
19200 bits/s
▪
38400 bits/s

Parity
Here the Modbus frame is parameterized with regard to parity and stop bit. The following options
are available:
▪
Even (1 stop bit)
▪
Odd (1 stop bit)
▪
None (2 stop bits)
▪
None (1 stop bit)
Byte order
Defines the order for the transmission of 2 byte values:
▪
MSB first (high byte is sent first)
▪
LSB first (low byte is sent first)
Register address
Here it is set on which address basis the register address is defined:
▪
0 based
▪
1 based
