Parameter name Function Data type
Valid range
(Default)
Validation timing
Write_Buffer_Address
_Offset
Set the offset of the
starting register of the
master sending data.
The setting value 1
means the offset is 1
word if the word
address of the slave is
written.
The setting value 1
means the offset is 1 bit
if the bit address of the
slave is written.
USINT
0~255
（0）
When Execute
changes from
FALSE to TRUE
Write_Destination_Ad
dress
Set the starting address
of the MODBUS slave
receiving the data from
the master
UINT
Standard Modbus
address
When Execute
changes from
FALSE to TRUE
Write_Length
The length of data to be
written
UINIT
Word register: 0~100
Bit device: 0~256
When Execute
changes from
FALSE to TRUE
Read_Buffer_Address
The starting register of
the master where data
received are stored.
UINT
%MW0~%MW32767
%QW0~%QW63
When Execute
changes from
FALSE to TRUE
Read_Buffer_Address
_Offset
Set the offset of the
starting register of the
master receiving data.
The setting value 1
means the offset is 1
word if the word register
of the slave are read.
The setting value 1
means the offset is 1 bit
if the bit register of the
slave are read.
USINT
0~255
(0)
When Execute
changes from
FALSE to TRUE
Read_Destination_Ad
dress
Set the starting address
of the MODBUS slave
to be read by the
master
UINT
Standard Modbus
address
When Execute
changes from
FALSE to TRUE
Read_Length
The length of data to be
read
UINT
Word register: 0~100
Bit register: 0~256
When Execute
changes from
FALSE to TRUE
Read_FunCode
Select the function code
used for reading Bit
address.
USINT
1: function code 01
2: function code 02
(2)
When Execute
changes from
FALSE to TRUE
Timeout
Set the time for the
master to wait for the
slave’s response. The
slave timeout occurs if
the slave does not
respond to the master
