Output signal for monitoring
The user can monitor a "Select success" signal at the output point "S4301_OSL_CSF", when
the SOFTSW1 function determines that the received "Remote-ON-Control" signal is true. If
the SOFTSW1 function determines that the "Remote-ON-Control" is not true, the SOFTSW1
function returns to the "Wait for a command" stage.

Figure 4.3-7 shows the logic when a "Select command (Remote-OFF-Control)" signal is applied
at the SOFTSW1 function. The input-point "S4301_CONTROL_REQ" is used for the reception
of the select command (Remote-OFF-Control).

Output signal for monitoring
The SOFTSW1 function, in Figure 4.3-7, can issue a "Select success" signal at output point
"S4301_FSL_CSF" when the SOFTSW1 function determines that the input signal "Select

"Remote-OFF-Control" is not true, the SOFTSW1 function returns to the "Wait for a command"
stage.
