When Xi terminal signal source is input as virtual terminal, whether the corresponding function of this
terminal is effective depends on the control of the host computer and has nothing to do with the real
status of the current Xi terminal.
When Yi, Y2 and relay terminals are output as virtual terminals, the real outputs of these terminals
depend on the control of the host computer and have nothing to do with whether the output terminal
function set is effective.
It defines the validity of the input and output status of the multifunctional digital terminals.
