Very few of the members of the forum have an Engineering Kit V2 so we do not know of what you write. Nor do we have a clue what a Simulink 5.4 is.
So, please, post the code here. Read the forum guidelines to see how to properly post code and some hints on how to get the best from this forum.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.
Post a schematic also.
