The following tables present all configuration language objects for communication Character mode. These objects are not integrated in the IODDTs, and may be displayed by the application program.

%KWr.m.c.0
|
INT
|
R
|
The byte 0 of this word corresponds to the type. Value 3 corresponds to Character Mode.
|
|
%KWr.m.c.1
|
INT
|
R
|
The byte 0 of this word corresponds to the transmission speed. This byte can take several values:
-
Value -2 (0xFE) corresponds to 300 bits/s
-
Value -1 (0xFF) corresponds to 600 bits/s
-
Value 0 (0x00) corresponds to 1200 bits/s
-
Value 1 (0x01) corresponds to 2400 bits/s
-
Value 2 (0x02) corresponds to 4800 bits/s
-
Value 3 (0x03) corresponds to 9600 bits/s (default value)
-
Value 4 (0x04) corresponds to 19200 bits/s
-
Value 5 (0x05) corresponds to 38400 bits/s
-
Value 6 (0x06) corresponds to 57600 bits/s (can be taken only for BMX NOM 0200 module)
-
Value 7 (0x07) corresponds to 115200 bits/s (can be taken only for BMX NOM 0200 module)
The byte 1 of this word corresponds to the format:
-
Bit 8: number of bits (1 = 8 bits (RTU), 0 = 7 bits (ASCII))
-
bit 9 = 1: parity management (1 = with, 0 = without)
-
Bit 10: parity Type (1 = odd, 0 = even)
-
Bit 11: number of stop bits (1 = 1 bit, 0 = 2 bits)
-
Bit 13: physical line (1 = RS232, 0 = RS485)
-
Bit 14: DTR/DSR/DCD modem signals. For BMX NOM 0200 module and if RS232 is selected, this bit can take 2 different values: 1 means that modem signals are managed, 0 means that they are not (default value for BMX P34 or if RS485 is selected)
-
Bit 15 : RTS/CTS hardware flow management signals. If RS232 is selected this bit can take 2 different values: 0 for RX/TX and 1 for RX/TX + RTS/CTS. If RS485 is selected the default value is 0 and corresponds to RX/TX
|
|
%KWr.m.c.2
|
INT
|
R
|
Entered value in ms of stop on silence (depends on the transmission speed and format selected). Value 0 means no silence detection.
|
|
%KWr.m.c.3
|
INT
|
R
|
This word correcponds to the polarization type:
-
Value 0 on both bit 14 and bit 15 corresponds to no polarization (This is the default value for BMX P34 or if RS232 is selected)
-
Bit 14: value 1 corresponds to low impedance (Modbus like) polarization and can be taken only for BMX NOM 0200 module and if RS485 is selected
-
Bit 15: value 1 corresponds to high impedance polarization and can be taken only for BMX NOM 0200 module and if RS485 is selected
|
|
%KWr.m.c.5
|
INT
|
R
|
This word corresponds to RTS/CTS delay time in hundreds of ms from 0 to 100 if RS232 is selected. If RS485 is selected the default value is 0.
|
|
%KWr.m.c.6
|
INT
|
R
|
Bit 0 of Byte 0 can have 2 values:
-
value 1 corresponds to the stop checkbox in the Stop on reception area for character 1 when checked
-
value 0 corresponds to the stop checkbox in the Stop on reception area for character 1 when unchecked
Bit 1 of Byte 0 can have 2 values:
-
value 1 corresponds to the Character Included checkbox in the Stop on reception area for character 1 when checked
-
value 0 corresponds to the Character Included checkbox in the Stop on reception area for character 1 when unchecked
Byte 1 of this word corresponds to the entered value of stop on reception of character 1 from 0 to 255.
|
|
%KWr.m.c.7
|
INT
|
R
|
Bit 0 of Byte 0 can have 2 values:
-
value 1 corresponds to the stop checkbox in the Stop on reception area for character 2 when checked
-
value 0 corresponds to the stop checkbox in the Stop on reception area for character 2 when unchecked
Bit 1 of Byte 0 can have 2 values:
-
value 1 corresponds to the Character Included checkbox in the Stop on reception area for character 2 when checked
-
value 0 corresponds to the Character Included checkbox in the Stop on reception area for character 2 when unchecked
Byte 1 of this word corresponds to the entered value of stop on reception of character 2 from 0 to 255.
