A significant exception to this rule is the Constant block,whose output data type is determined by the data type of its parameter. If the output of a block is a function of an input and a parameter,and the input and parameter differ in type,the Simulink software converts the parameter to the input type before computing the output. .In general,a block outputs the data type that appears at its inputs.

The elements of a signal array connected to a port of a nonvirtual block must be of the same data type. The signals connected to the input data ports of a nonvirtual block cannot differ in type.
