S5-115U Manual
Mode number
The table below explains the mode numbers. The default refers to word 7 in the ASCII parameter
set (see Table 12-10). The mode numbers must be defined in system data word 55 (see
Section 12.4.5).
Mode
Send n bytes; n
mailbox.
1
Receive m bytes; m
Send or receive data until the end character (low-order byte) defined
2
in the parameter set is sent or received. The end character is also
transmitted.
Send or receive data until the two end characters defined in the
parameter set are sent or received. Both end characters are
3
transmitted.
End of text is recognized only when the character defined in the
high-order byte is sent or received before the character defined in
the low-order byte.
Same as mode 2. The following ASCII characters are interpreted upon
reception:
4
RUB OUT : delete last character
XON
: forward
XOFF
: interrupt send and wait for XON
Same as mode 3. The following ASCII characters are interpreted upon
reception:
5
RUB OUT : delete last character
XON
: forward
XOFF
: interrupt send and wait for XON
Printer Output
Transmit send mailbox until an end character defined in the
6
parameter set (low byte) is reached. The end character is not
transmitted.
Only XON and XOFF can be received. These characters are also
interpreted.
Printer Output
Send n bytes; n must be specified in the first word of the Send
7
mailbox. (n is not transmitted.)
Only XON and XOFF can be received. These characters are also
interpreted.
As in mode 1; the following ASCII characters are also interpreted
when received
8
RUB OUT
***
XON
XOFF
*
n is variable when sending
**
m is fixed when receiving
***
If a received message frame of m bytes contains a RUB OUT, correspondingly less data is entered in the receive mail-
box and the character delay time activates error 01 in CBR.
