Abstract
A numerical control system exchanges input/output signals between a numerical controller and an IO unit and the IO unit includes a first control unit that changes an idle signal output from the IO unit using an input signal as a trigger to a specific waveform pattern signal and when the specific waveform pattern signal is received, transmits the specific waveform pattern signal to a former side. The numerical controller includes a second control unit that outputs an interrupt signal when the specific waveform pattern signal is received.
Claims10
A numerical control system having a numerical controller and one or a plurality of IO units connected to the numerical controller and in which input/output signals are configured to be exchanged between the numerical controller and the IO unit via serial communication, the IO unit comprising:
- a first control unit configured to change an idle signal output from the IO unit using an input signal as a trigger to a preset specific waveform pattern signal and, transmit the specific waveform pattern signal to a former side when the specific waveform pattern signal is received and,
- the numerical controller comprising:
- a second control unit configured to output an interrupt signal when the specific waveform pattern signal is received.
A numerical control system having a numerical controller and one or a plurality of IO units connected to the numerical controller and in which input/output signals are configured to be exchanged between the numerical controller and the IO unit via serial communication, the IO unit comprising:
- a receiving unit configured to determine a type of an input signal input into the IO unit;
- and,
- a third control unit configured to preset a specific waveform pattern of an idle signal output from the IO unit for each of the types of the input signal and output the preset specific waveform pattern of the idle signal output from the IO unit in accordance with the type of the input signal as a trigger;
- and,
- the numerical controller comprising:
- a fourth control unit configured to determine the type of the input signal in accordance with a specific waveform pattern signal when the specific waveform pattern is received.
