Description
Specifying end detec-
tion
After character delay
time elapses
On receipt of fixed num-
ber of characters
On receipt of the end
delimiter(s)
After character delay
time elapses
Specifies the end detection of a received frame:
• After character delay time elapses:
The frame has neither a fixed length nor de-
fined end delimiters. The end of a frame is
indicated by a gap in the character se-
quence. The size of this gap is specified by
the character delay time.
• On receipt of fixed number of characters:
The length of the received frames is always
the same. When data is received, the end of
the frame is recognized when the set num-
ber of characters has been received.
• On receipt of the end delimiter(s):
At the end of the frame, there are one or
two defined end delimiters. When data is re-
ceived, the end of the frame is recognized
when the configured end delimiter(s) is/are
received.
No. of end delimiters
1
2
1
Selection of the number of end delimiters.
A maximum of two end delimiters can be con-
figured. When data is received, the end of the
frame is recognized when the selected end
delimiter combination is received.
1st end delimiter
0...255
3
Entry of the first end delimiter of a maximum of
two end delimiters for the end criteria "On re-
ceipt of the end delimiter(s)". The selected end
delimiter or the selected end delimiter combina-
tion limits the length of the frame.
Parameter value depending on the "Data bits"
parameter.
2nd end delimiter
0...255
0
Entry of the second end delimiter of a maximum
of two end delimiters for the end criteria "On
receipt of the end delimiter(s)". The selected
end delimiter combination limits the length of
the frame.
Parameter value depending on the "Data bits"
parameter.
Frame length
1...233
233
Entry of the frame length in bytes for the end
criterion "On receipt of fixed number of charac-
ters".
Character delay time
0...65535
150
Entry of the time [ms] that can elapse until a
frame end is recognized. Select the character
delay time dependent on the sending behavior
of your communication partner. Depending on
the data transmission speed the character delay
time is limited to a minimum value.
Note that applications also pause between two
frames during transmission.
