Parameter

Range

Description

Swap Code

0, 1, 2, 3

This parameter defines if the data received from the slave is to be
ordered differently than received from the slave device. This

parameter is helpful when dealing with floating-point or other multi-

register values, as there is no standard method of storage of these

data types in slave devices. This parameter can be set to order the
register data received in an order useful by other applications. The

following table defines the values and their associated operations:

Swap
Code

Description

0

None: No Change is made in the byte ordering (1234
= 1234)

1

Words: The words are swapped (1234=3412)

2

Words & Bytes - The words are swapped then the

bytes in each word are swapped (1234=4321)

3

Bytes: The bytes in each word are swapped
(1234=2143)

Node Address 1 to 255

(255 =
broadcast)

This parameter specifies the slave node address on the network to

be considered. Values of 1 to 255 are permitted. If the value is set

to 255, the command will be a broadcast message on the network.
The DF1 protocol permits broadcast commands for write

operations. Do not use this node address for read operations.
