The data between the communication partners are transferred via the serial interface by
means of a character frame. This means that each character may be recognized at the
receiver and the transmission may be checked for errors.
Please regard that all the following parameters must have the same set-
tings on every communication partner.
Description
Number of bits that are displayed on a character. On
Modbus RTU protocol 8 data bits are preset.
n
Range of values: 8 (fix)
When data is transmitted, stop bits are appended to each
character to be sent in order to signal the end of a char-
acter.
n
Range of values: 1, 2
The addition of its value "0" or "1" brings the value of all
the bits (data bits and parity bit) up to a defined status.
