Here end character(s) may be defined or the length set in the FB may be specified as
soon as "End character" is activated at the end ID.
Description
For communication with end character(s) maximally 2 end
characters may be defined.
The length of the respective telegram is limited by an end
character.
n
Range of values: 0...7Fh/FFh (7/8 data bits)
Here the transfer speed may be selected from a selection list.
Description
Transfer speed in bit/s
n
Range of values: 300, 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600, 76800
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 onto which a character is mapped.
n
Range of values: 7, 8
When data is transmitted, stop bits are appended to each
character to be sent in order to signal the end of a char-
acter.
Range of values: 1, 2
n
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.
n
Range of values: none, odd, even
Data flow control synchronizes data transmission when one communication partner works
faster than the other with ASCII. Here the type of data flow control may be set and its
associated parameters.
At half-duplex parameterization with RS485 data flow control is not pos-
sible.
