SWAP WORDS
SWAP WORDS & BYTES
SWAP BYTES
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.
No change is made in the byte ordering (1234 = 1234)
The words are swapped (1234=3412)
The words are swapped, then the bytes in each word are swapped
(1234=4321)
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). All
other service port values will generate a Modbus command message
encapsulated in a TCP/IP packet.
Slave Address
0 - Broadcast to all nodes
1 to 255
Use this parameter to specify the slave address of a remote Modbus Serial
device through a Modbus Ethernet to Serial converter.
