摘要： A numerical control system for controlling a machine tool includes a central processing unit, a first memory for storing a first control program, a second memory for storing a second control program, and a third memory for temporarily storing data. Each of the first memory, second memory and third memory is connected to the central processing unit. An interface circuit couples a machine tool to the central processing unit. The interface circuit sends signals to and receives signals from the machine tool. The first control program sends signals to and receives signals from the third memory based on a standard interface with the machine tool. The second control program sends signals to and receives signals from the machine tool via the interface circuit based on an interface corresponding to the machine tool. The second control program also sets a signal from the machine tool in the third memory after converting it to a signal based on a standard interface.

摘要： Disclosed is a signal transfer control system of a programmable controller for transferring I/O signals between the PC and an external device. An I/O unit (26) includes an I/O signal region (1) for storing I/O signals transferred or received to or from an external device, and mapping data (2) for defining the mapping of the I/O signal region (1). Further, a RAM (23) of the PC includes point data (3) for defining the address to which I/O signals from the mapping data (2) are to be transferred, and an I/O data region (4) for storing the I/O data. Input signals are stored in the I/O signal region (1) and each of the I/O signals is mapped by the mapping data (2), and the point data (3) determines the address to which each of the mapped input signals is to be transferred. Namely, the addresses to which the input signals are to be transferred are determined by the mapping data (2) and the point data (3), and the input signals are then transferred to the I/O data region (4). Conversely, the input signals are transferred from the I/O data region (4) to the I/O signal region (1) by the point data (3) and the mapping data (2). Therefore, even if the arrangement of these I/O signals is changed, the change can be dealt with by changing the point data or the mapping data, without the need to change a sequence program.

摘要： A bidirectional communications link, termed a customization window, comprises a series of routines including functions, procedures and status flags implemented in software, interfaced between a machine control logic (MCL) operating to control the auxiliary functions of a computerized numerical control (CNC) system and a numerical control (NC) operating to control the multi-axis motions of the system whereby the MCL, implemented in software, can access the NC, also implemented in software, and control the system but only under conditions dictated by the NC and enforced by the routines of the customization window so that, for example, the integrity of the NC software will not be compromised by any of the MCL software which is of a user programmable type. Additionally, machine setup data and the availability of optional system control features are routed from the NC to the MCL through the customization window. Also the customization window conveys the status of the various operational conditions of the NC to the MCL.
