Abstract

PURPOSE:To make the program for plural microcomputers same, by setting the same program for each microcomputer and selecting a processing routine among the programs based on the signal which is set from outside. CONSTITUTION:An input port 9-A of a microcomputer of group A is set at a high level, and an input port 9-B of a group B is set at a low level. A CPU1-A reads the signal of the port 9-A and selects the processin routine of the group A and a common processing routine of both groups A and B based on the program stored in an ROM3-A. An A group process and then the A/B group common process are carried out to the data given from a machine tool via an input/ output port 7-A, and this data is fed to the machine tool via the port 7-A. For the microcomputer of the group B, the A group process plus the A/B group common process are carried out to the data fed via an input/output port 7-B. Then the data is fed to the machine tool.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system comprising a plurality of microcomputers that controls a machine tool, and more particularly to a control method and apparatus for a machine tool in which each microcomputer uses the same processing program.

Conventionally, in machine tools, failures and malfunctions have been prevented by mutually monitoring various controls using multiple microcomputers.

However, in each microcomputer,
Even if the addresses of the input/output board, data memory, etc. are exactly the same as those of other microcomputers, if the processing performed in each microcomputer is even slightly different, the processing program may be different from the program memory of the other microcomputer. It was necessary to prepare a program memory to store the data, which was a disadvantage in terms of management, and also caused an increase in costs in the case of mass production.

The present invention has been made in view of the above, and its purpose is to make the programs of a plurality of microcomputers that control a machine tool completely the same. In order to achieve the above-mentioned clause (1), in a device in which a machine tool is controlled by a plurality of Mitaro convenience stores, a program memory including the aforementioned 6h Mitaro computer in which the same program program is stored; @ in Pudatsumu
The present invention is advantageous in that the micro combinator KA is configured to include testing means provided in each of the micro combinators KA to which a signal for routine selection is input.

Hereinafter, using the diagram, I will explain about 111f'aK of Tono.

III shows an example of this threat, and j19. One is the Mu type and the other is the 1 type. l-m, 3-m, tom 4゜γ-m, and 9-m are 凰011 [(leadσsly M*vm*
rl), temporary data storage layer 凰M (shii・ugim@@@@llid@ff1lr7), an input/output port for exchanging signals with the machine tool, an input port that constitutes the lIP setting means. It is. On the other hand, t1゜$-1, 1-1,'
1f-1 and 11-1 are the CPUs of the L-series Mitaro computer, the LOM which stores the same program as that stored in the M-series 凰0M3-M, the ROM for temporary storage of data, and the work. It is an input/output port for exchanging ministerial regulations with machines, and an input port that constitutes a crotch means.

The address assigned to each instruction in the 11KE of processing contents and 11KE of the 1OMB-1 and 1-1 of the 11KE of the MU system and 1 KE is the address assigned to each instruction, and the program is, for example, a MU system layer routine, They are broadly divided into l-system processing routines and mu/waki common processing l routines.

The input ports 9-1 of the system and l system are the upper [
In order to select the processing routine stored in the ROMK, the same address is set for the above input ports. For example, the input port for the system system is set to 7-level (2), and the input port for the system 1 is set to level (2). When the signal IJ is inputted, the CPU 1-A and the CPU 4 select the processing routine to be processed.

In detail, the number of input signals is not limited to one; the number of input signals can be increased according to the number of microconvenience stores used, and multiple signals can be input by combining the signals. There is no need to worry about being able to select a processing routine.

No.! (2) shows a flowchart showing the process idleness of the CPU 1 of the M system and the I system.

Next, to explain the operation of this invention along with the second part, first, in the A-series miterrocomputer, the input port 9
Since the signal being applied from the CPU 1-2 is at the 1st level, the CPU 1-2 will be able to read the scissors signal. Perform routine routines and routine processing. Then, regarding the data inputted from the machine tool (II not shown) through the personnel support arm,
After doing the Mu-based treatment as shown in the chart, do the Mu-door common procedure, $11! The machine tool kI and layered signals are outputted through the input/output port 7-me.

Next, in the %1 series microcombiator, since the signal applied to input port 4 is at a temporary level (transition), CIFυ port 1 reads this signal.
诱0M3-IK Selects the %l system processing routine and the M/l joint processing routine from the stored program programs. Then, as shown in the 71-chart in *2■, the machine tool (I
Regarding the data input through the input/output port 1 (input/output port 1), after performing the system processing, the common processing is performed on the data input/output port 1). -1, the machine tool ecast signal is output.

Therefore, according to this embodiment, since the processing routine is selected from among the logs stored in the fragile 0M11C by the ministerial ordinance 41juC from the input port, both the A base axis and the 1 system are @mory ) K
The program modules to be stored can be the same.

Furthermore, KJI and the system's pipe layer ■ are met.
In the case of large quantities of Imamaro, there is a point that it leads to cost reduction.

**Since the configuration is as in III of the above-mentioned request for permission, it is possible to use the same program for a plurality of microcomputers that control the machine tool.

Note that the present invention is not limited to the above-mentioned embodiments, and may be implemented in other embodiments by making appropriate changes.
