Abstract
Abstract A numerical control system in which an external computer such as a microcomputer is used for controlling and communicating with a numerical control device. A first memory is provided for storing data control character codes for the external computer, while a second memory is provided for accessing the contents of the first memory for translating communications data used in data communications between the computer and the numerical control device. The contents of the first memory are determined so as to allow the numerical control device to perform data communications with an external computer employing different data control character codes.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A numerical control device having a data transmitting function for performing data communications with an external computer, comprising: a first memory for storing data control character codes for said external computer; a second memory and processor means for accessing contents of said first memory for translating communications data used in said data communications; and interface transmission means for coupling said second memory to said external computer, contents of said first memory being determined so as to allow said numerical control device to perform data communications with another external computer employing different data control character codes, said first memory storing data code pairs wherein, in each of said pairs, one data code value corresponds to a code employed by said external computer and the other value corresponds to a code employed by said numerical control device for effecting a like function as said code value of said external computer.
Claim 2
Dependent Claim
148 words
A numerical control device having a data transmitting function for performing data communications with an external computer, comprising: a first memory for storing data control character codes for said external computer; a second memory and processor means for accessing contents of said first memory for translating communications data used in said data communications; and interface transmission means for coupling said second memory to said external computer, contents of said first memory being determined so as to allow said numerical control device to perform data communications with another external computer employing different data control character codes, said first memory storing data code pairs wherein, in each of said pairs, one data code value corresponds to a code employed by said external computer and the other value corresponds to a code employed by said numerical control device for effecting a like function as said code value of said external computer.
Claim 3
Dependent Claim
14 words
The numerical control device of claim 1, wherein said external computer comprises a microcomputer.
Claim 4
Dependent Claim
21 words
