P7.T4
It controls the action of the multi-function input terminal or output terminal by the host computer.
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 no relationship with the real
status of the current Xi terminal.
When Yi, YT and relay terminals are output as virtual terminals, the terminal output depend on the control
of the host computer and have no relationship with the parameter setting.
P7.T5
It defines the validity of the input and output status of the multi-function digital terminals.

When the digital input Xi terminal and COM terminal are short together, whether the input status is valid
by judging whether there is current flowing through the terminals.
When the digital output Yi terminal acts as open collector output, whether the output status is valid by
judging whether there is current flowing through the terminal.
Whether the relay output status is valid by judging whether the relay is in the magnetizing status.
