Numerical control system with plural groups of miscellaneous functions
First Claim
1. A numerical control system for controlling a machine based on a machining program, comprising:
- a numerical control section for outputting numerical control signals based on the machining program, comprising;
memory means for storing miscellaneous function instructions divided into plural groups; and
interface means for outputting a specific miscellaneous function instruction from among the divided miscellaneous function instructions as well as a code read command signal including a group number to which the specific miscellaneous function instruction belongs; and
a programmable controller section, operatively connected to the numerical control section and the machine, for executing sequential control of the machine based on the numerical control signals from said numerical control section, comprising;
decoding means for decoding the specific miscellaneous function instruction on the basis of the code read command signal sent by the numerical control section; and
miscellaneous function executing means for executing the sequential control of the machine in accordance with a plurality of decoded miscellaneous function instructions.

Abstract
A numerical control system of a machine tool or the like has a numerical control section and a programmable controller section for executing sequential control of a machine based on control signals from the numerical control section. Miscellaneous function instructions from the numerical control section are divided into a plurality of groups and miscellaneous function code signals specified for each group are outputted in parallel. The programmable controller section executes sequential control of the machine on the basis of the miscellaneous function code signals of each group received in parallel from the numerical control section.
