Q16 To Byte SI
Converts Q15.16 to four byte SI
Category: Conversion
Description:
In situation where it is necessary to use CAN Output or RS485 Output, the payload data must be split into bytes. If it is necessary for the information to retain its data in their respective bits, the Q16 To Byte SI block can be used. Figure 1 shows the difference between Q16 To Byte SI and Q16 To Byte.

As can be seen, there is a difference in the output of the blocks. Consequently, only the Q16 To Byte SI block has the capability to convert negative and fractional values into bytes while preserving their information. Figure 2 shows an example.
