Abstract
In a numerical control system in which a numerical controller and an I/O unit perform serial data communication through a communication line, a counter of the I/O unit starts time measurement with an input signal from an in-machine measurement device as a trigger and stops counting at the start of transmission of DI data. The I/O unit transmits a flag indicative of input of the input signal as a trigger and a value in the stopped counter to the numerical controller. Based on a time value measured by a timer and the counter value, the numerical controller calculates the time of input of the input signal.
