Abstract
A numerical controller is chain-connected with a plurality of I/O units so that it transmits DI/DO signals to and receives DI/DO signals from the I/O units by master-slave communication. The numerical controller counts signals generated by a timer circuit up to a predetermined number and sets, from among the plurality of I/O units, an I/O unit with which transfer of the DI/DO signals is to be performed for each count value. The DI/DO signals of the set I/O units are transferred according to the count value.
