LIN Pack block can't handle signals with offset

when i use lin pack block to pack signals with offset, i find the lin pack block can only handle uint8 sig, that can't represent signed or float data.

so, how can i do with the sig, whitch has offset or factor?

Are you dealing with signals with bias https://www.mathworks.com/help/simulink/slref/bias.html or signals with sample rate offset https://www.mathworks.com/help/comm/ref/samplerateoffset.html

No. For example, I have a signal with -45 offset and 90 maximum, we can see that:

When I give it zero, the output data is 45, I can not represent less then 45 because it only accepts uint8 as input.

Even I give it 245, try to make it overflow, the output data will also limit in 90.

That sounds like you are using a bias block, but you say "No" to my question of whether you are using a bias block?

Is that a LIN pack block? The LIN pack block that I find only accepts a single input port, and does not have any sort of bias ?

[Lucas]

It is the LIN pack block.

When you select a LDF file, it can parse the file and generate ports of all the singles of the selected frame. I'm not mean to hanle a single signal with offset witch you said "bias" block. I want use LIN pack block to parse LDF file and auto handle all signals of a lin frame, and output a LIN Data. I dont know it is a bug of the "LIN pack block" or there are something i dont find.
