Functions 5 and 6 ignore this field as they apply only to a single data point.
For functions 1, 2, and 15, this parameter sets the number of bits (inputs or
coils) to be transferred by the command.
For functions 3, 4, and 16, this parameter sets the number of registers to be
transferred by the command.

This parameter defines if and how the order of bytes in data received or sent is to
be rearranged. This option exists to allow for the fact that different manufacturers
store and transmit multi-byte data in different combinations. This parameter is
helpful when dealing with floating-point or other multi-byte values, as there is no
one standard method of storing these data types. The parameter can be set to
rearrange the byte order of data received or sent into an order more useful or
convenient for other applications. The following table defines the valid
Swap
Code
values and the effect they have on the byte-order of the data.
Swap Code
Description
N
ONE
No change is made in the byte ordering (1234 = 1234)
S
WAP
W
ORDS
The words are swapped (1234=3412)
S
WAP
W
ORDS
&
B
YTES
The words are swapped, then the bytes in each word are swapped
(1234=4321)
S
WAP
B
YTES
The bytes in each word are swapped (1234=2143)
These swap operations affect 4-byte (or 2-word) groups of data. Therefore, data
swapping using these
Swap Codes
should be done only when using an even
number of words, such as when 32-bit integer or floating-point data is involved.
Node IP Address
xxx.xxx.xxx.xxx
The IP address of the device being addressed by the command.
Service Port
502
or other port numbers supported on a server
Use a value of
502
when addressing Modbus TCP/IP servers that are compatible
with the Schneider Electric MBAP specifications (this will be most devices). If a
server implementation supports another service port, enter the value here.
Slave Address
