23 Weight Used to scale register value when not in
engineering units.
Scaled = (weight * register value) +
offset 1.0
Floating point value – e.g. 0.25
Range -999999.0 to 999999.0
24 Offset Used to scale register value when not in
engineering units.
Scaled = (weight * register value) +
offset
0.0
Floating point value – e.g. -25.0
Range -999999.0 to 999999.0
27 Signed Indicates that the register contains a

25 Endian When reading double registers, this
defines the byte ordering in the register
pair.
Example: Double register value (hex) =
0x12345678
If order is Big Endian:
Register x = 1234
Register x+1 = 5678
If order is Little Endian:
Register x = 5678
Register x+1 = 1234
Big Endian
[1]
0 = Little Endian
1 = Big Endian
