Extended status/con-
trol mode
0 = no
1 = yes
If the Extended status/control mode is activated, the
diagnostic messages are mapped into byte 6 of the
process input data (independent of parameter ”deacti-
vate diagnostics”).
Byte 6 of the process output data contains two bits
which may be set to flush the transmit- or the receive-
buffer.
Byte 7 contains the status or control byte. User data are
represented in Bytes 0 - 5.
Deactivate all diagnos-
tics
0 = no
1 = yes
Sending of diagnostics activated/deactivated:
This affects the separate fieldbus-specific diagnostic
message – not the diagnosis embedded in the process
input data.
Stop bits 0 = 1 Number of stop bits.
1 + 2
Parity 00 = none
01 = odd The parity bit is set so that the total number of bits (data
bits plus parity bit) set to 1 is odd.
10 = even The parity bit is set so that the total number of bits (data
bits plus parity bit) set to 1 is even.
Data bits 0 = 7 The number of data bits is 7.
1 + 8 The number of data bits is 8.
Data flow control 00 = none The data flow control is
switched off.
01 = XON/XOFF Software handshake (XON/
XOFF) is switched on.
XON character
(RS422)
0 - 255
(17)
XON character
This character is used to start the transmission of data
from the data terminal device if the software hand-
shake is active.
XOFF character
(RS422)
0 - 255
(19)
XOFF character
This character is used to stop the transmission of data
from the data terminal device if the software handshake
is active.
