Abstract
In a numerical control system including a numerical controller and a plurality of I/O units, a serial communication signal monitoring circuit is included inside the I/O unit to monitor a serial communication signal (data and an idle signal). When a state is detected in which a serial communication signal is high or low for a predetermined time or longer, the numerical control system acknowledges the state as disconnection of the serial communication signal, and generates a reset pulse signal to reset an internal register of the I/O unit. With this configuration, when the power supply of the numerical controller is turned off/on, it is unnecessary to turn off/on the power supply of the I/O unit.
