BYTE ORDER
MODBUS register:
Data type:
Access:
6305
4915
Integer
read/write
For selecting the byte transmission sequence for the Integer, Float and String data
types.
Options:
0 = 0-1-2-3
1 = 3-2-1-0
2 = 2-3-0-1
3 = 1-0-3-2
Factory setting: 1-0-3-2
! Note!
• The transmission sequence must suit the MODBUS master.
• More information can be found in Operating Instructions BA107D under the
keyword “Byte transmission sequence”.
DELAY TELEGRAM
REPLY
MODBUS register:
Data type:
Access:
6306
4916
Float
read/write
For entering a delay time after which the measuring device replies to the request
telegram of the MODBUS master. This allows communication to be adapted to

WRITE
PROTECTION
MODBUS register:
Data type:
Access:
6307
4918
Integer
read
Indicates whether write access to the measuring device is possible via local
operation or MODBUS RS485.
Display:
0 = OFF (write access via MODBUS possible)
1 = ON (write access via MODBUS blocked)
Factory setting: OFF
! Note!
Hardware write protection is activated and deactivated by means of a jumper on
the I/O module (see Operating Instructions BA107D).

5051 to 5081.
User input: 0 to 9999
Factory setting: 0
! Note!
More detailed information and examples of using the auto-scan buffer are
provided in Operating Instructions BA107D.
