What are you trying to do? is it a PLC? Are you wanting to set an output from a macro or a button or?

Hi£¬Hood£º
    Now£¬I design a board like ModIO, the input signal is test ok, but I cann't understand the output signal setup.
I want set the output like the input and can from a macro.

Well for me with the PLC it is as simple as

Call SetModOutPut (19,1)

That would turn on output 19

I have no idea about what is sent, the registers in the PLC start at 2048 for inputs (PLC Inputs, Mach Outputs) and thats what I have set up in the above screenset.
