Modbus - 32-bit integers

The long integers are implemented in the same manner as the floating-point numbers.

Register	Mapping	Swap mode	Bytes in 2 16 - bit registers	Resulting 32 - bit floating point
Hd	Holding registers	N/A	[a b][c d]	[a b c d]
Hds	Holding registers	Byte and word swap	[a b][c d]	[d c b a]
Hdsb	Holding registers	Byte swap	[a b][c d]	[b a d c]
Hdsw	Holding registers	Word swap	[a b][c d]	[c d a b]
Rd	Input registers	N/A	[a b][c d]	[a b c d]
Rds	Input registers	Byte and word swap	[a b][c d]	[d c b a]
Rdsb	Input registers	Byte swap	[a b][c d]	[b a d c]
Rdsw	Input registers	Word swap	[a b][c d]	[c d a b]
