When a wireless slave station is added during startup, the
error can be determined by the LEDs (WS LED, LED display)
of the wireless master station, which is the master station of
the network. Since wireless communication errors cannot be
determined by the LEDs due to the interference wave in the
middle of communication, this is made possible by using the
test function of the wireless unit, etc.
