Numerical controller for communication with I/O units |
摘要 |
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. |

1. A numerical controller for communication with I/O units, wherein the numerical controller is chain-connected with the 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 comprising:
a timer circuit configured to generate a signal every predetermined period; a counter unit configured to count the number of signals generated by the timer circuit up to a predetermined number; an I/O unit transfer order setting unit configured to set, from among the I/O units, an I/O unit with which transfer of the DI/DO signals is to be performed for each count value of the counter unit; an I/O unit transfer period group setting unit configured to divide the I/O units into groups according to the transfer period of the DI/DO signals; and an automatic setting unit configured to automatically perform the setting of the I/O unit transfer order setting unit, based on contents set by the I/O unit transfer period group setting unit; wherein the DI/DO signals of the I/O units set in the I/O unit transfer order setting unit are transferred according to the count value of the counter unit, wherein information set in the I/O unit transfer period group setting unit comprises order information of the I/O units according to a distance from the numerical controller, and wherein the automatic setting unit sets the I/O units to which the DI/DO signals are transferred in the I/O unit transfer order setting unit, based on the order information. |
