how to solve mismatch data types

as the attachment I have tried to convert the input data type "double" to the output data type "int32" to meet the final requirement of "out_dac_1", but appear errors as attachment. I think this error kind of related to the mismatch data types, and how to convert the data type correctly? thanks very much for help.
