Hello @CZ_FB,
Unfortunately, this requirement is not possible right away, because it requires a serious update/patch coming from the MBDT team. We have to redesign and modify the blocks from the toolbox to accept both the CID and the Instance as a block input. I will open a ticket for such changes, but because we have no roadmap to cover a new release for the MBDT for S32K1, I cannot promise this will be implemented.
To faster help you with such requirements, I can identify 2 options:
1. You could use a switch case, and in each case place a block to handle the CID and Instance you need to cover.
2. The second option would be to create a block that uses custom code, after a template or method described in this article https://community.nxp.com/t5/NXP-Model-Based-Design-Tools/How-to-use-your-own-C-code-in-our-Toolbox-...
How many BCCs do you need to cover?
Regards,
Marius
