Parameter name Value Meaning
transmission rate 0000 = 300 bps
0001 = 600 bps
0010 = 1200 bps
0100 = 2400 bps
0101 = 4800 bps
0110 = 9600 bps
A
0111 = 14400 bps
1000 = 19200 bps
1001 = 28800 bps
1010 = 38400 bps
1011 = 57600 bps
1100 = 115200 bps
RS422/RS485 0 = RS422
1 = RS485
Parameterization of the module as RS422 or RS485-
interface.
Extended status/con-
trol mode
0 = no
1 = yes
A
If the Extended status/control mode is activated, the
diagnostic messages are mapped into byte 6 of the
process input data (independent of parameter "deac-
tivate 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 diagnos-
tics
0 =no
A
1 = yes
Sending of diagnostics activated/deactivated:
This affects the separate fieldbus-specific diagnostic
message – not the diagnosis embedded in the pro-
cess input data.
Stop bits 0 = 1 Number of stop bits.
1 = 2
A
Parity bit 00 = none
01 = odd
A 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
A 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.
