DATA TRANSFER SYSTEM FOR NUMERICAL CONTROLLER
Document Type and Number:
Japanese Patent JPH0442308
Kind Code:
A
Abstract:
PURPOSE:To increase the processing speed of a numerical control part by securing the residence of a library program at each function part and applying the direct accesses to the data area, etc., of the numerical control part. CONSTITUTION:A library program 23 that can have a direct access to a numerical control part 10 is previously transferred to a programmable machine controller PMC 20, etc., at application of a power supply. An application program 22 of the PMC 20, etc., gives a command to the program 23 to have the accesses to the necessary data. Thus the program 23 has a direct access tot he instructed data on the part 10 and transfers this data to the PMC 20, etc. As a result, the processing is carried out at a high speed at the part 10.
