Make a program containing all the common communication code. Now use a case structure to select between the three different data constructs.

Your code is overly complicated. There is way too much unnecessary stuff (e.g. (1) Use a U8 array diagram constant instead of building U8 arrays from dozens of scalar U8s. (2) In some places you convert to a string and back to U8 array for no reason at all, (3) etc...)

my code is depend on the instruction book of dispense unit, i think that better use a SUBVI to combine them

I don't know what that means. Can you explain?

Yes for example the command for the pressure is stx 0EPH_ _CH200P[][][][]?? ,[][][][] means the pressure,?? is the checksum. therefore if want to set the right command should calculate the cheksum. my program include these

can you teach me how to combine them on one front panel?
