NUMERICAL CONTROLLER AND NUMERICAL CONTROL SYSTEM IN WHICH THE CONTROLLER IS CONNECTED BY NETWORK

摘要

A numerical controller in the present invention includes a bus trace circuit configured to fetch a bus cycle satisfying preset conditions, an alarm history, an alarm data acquisition table in which whether to acquire trace data is recorded for each alarm, and a trace circuit setting table in which fetching conditions of the bus cycle of the bus trace circuit are recorded for each alarm, and identifies an alarm for which the trace data is to be fetched from the alarm history and the alarm data acquisition table, reads the fetching conditions of the bus cycle corresponding to the alarm from the trace circuit setting table, sets the fetching conditions to the bus trace circuit, and acquires the trace data of the bus cycle based on the fetching conditions that are set through the bus trace circuit.

1. A numerical controller having a data acquisition function that acquires trace data of a bus cycle of an internal bus,
the numerical controller comprising: a bus trace circuit configured to fetch the bus cycle satisfying preset conditions; an alarm history; an alarm data acquisition table in which whether to acquire the trace data is recorded for each alarm; and a trace circuit setting table in which fetching conditions of the bus cycle of the bus trace circuit are recorded for each alarm, wherein the numerical controller identifies an alarm for which the trace data is to be fetched from the alarm history and the alarm data acquisition table, reads the fetching conditions of the bus cycle corresponding to the alarm from the trace circuit setting table, and sets the fetching conditions to the bus trace circuit and the bus trace circuit acquires the trace data of the bus cycle based on the fetching conditions that are set.
