Modbus Modbus RTU interface 0 / 1
If one of the two Modbus RTU interfaces is set to Slave, the following input fields
are available:
Baud rate
The baud rate influences the transmission speed between the individual
components connected in the system. When selecting the baud rate, en-
sure that it is the same at both the sending and receiving end.
Parity
The parity bit can be used to check the parity. It detects transmission er-
rors. A parity bit can safeguard a specific number of bits. The value (0 or 1)
of the parity bit must be calculated by the sender and is checked by the
recipient using the same calculation. The parity bit can be calculated for
even and odd parity.
