Abstract

PURPOSE:To set a control switch to be selected by a parameter by performing operation based on the parameter, which is housed to a first memory, and a signal at the time of non-operation, outputting an operating signal when the operating signal is effective and outputting the signal at the time of non- operation when the operating signal is ineffective. CONSTITUTION:The parameter, for which a specified value is given in correspondence to control switches 11-15 to be regarded as effective, is housed to a first memory 24a. The state of the signal at the time of non-operation is stored to a second memory 23. The operating signal is inputted and the prescribed arithmetic is executed based on the parameter, for which this operating signal is housed to the first memory 24a, and the signal at the time of non-operation. By this arithmetic, the operating signals of the control switches 11-15, which are set effective by the parameter, are outputted. However, for the control switch to be set ineffective, the signal at the time of non-operation is outputted. Thus, since the control switches 11-15 to be regarded as effective can be selected by the parameter, it is not necessary to separate the control switches 11-15 by a protection cover, etc.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a function selection method for an operation switch provided on an operation panel etc. to select whether or not to enable the function of the operation switch, and particularly to The present invention relates to a function selection method for an operation switch in which the operation switch is set by a parameter.

[Conventional technology] In recent years, as the functionality of numerical control units (CNC) has improved and machine tools have become more sophisticated, a large number of operation switches have been installed on the operation panels of numerically controlled machine tools (NC machine tools). ing.

On the other hand, even if such a large number of operation switches are provided, only a limited number of operation switches are operated during normal operation, and the number of operations is large. Therefore, there is a risk that carelessness or erroneous operation by an inexperienced operator may occur. Therefore, when performing such a simple operation, conventionally, operation switches that are not necessary for the operation are covered one by one or in blocks together with a protective cover.

[Problem to be solved by the invention]

However, not only for such simple operations but also for operating other operation switches, the protective cover must be removed, and the removed protective cover must be stored in another location, which is troublesome. Further, the operating switches used may differ depending on the type of operation, and in such cases, protective covers grouped into blocks cannot be used unless the shape of the protective covers is changed.

The present invention has been made in view of these points, and it is an object of the present invention to provide a function selection method for an operation switch in which seven operation switches to be selected are set by parameters.

[Means to solve the problem]

In order to solve the above problems, the present invention provides a function selection method for an operation switch that selects whether or not to enable a function of the operation switch, in which an operation signal of the operation switch is enabled in correspondence with the operation switch. a parameter setting whether or not to operate is stored in a first memory, a signal when the operation switch is not operated is stored in a second memory, the operation signal is input, and the determination means determines whether the operation signal is Performing a predetermined calculation based on the parameter and the non-operation signal to determine the validity of the operation signal, outputting the operation signal if the result of the determination is valid, and outputting the operation signal as a result of the determination. Provided is a function selection method for an operation switch, which outputs the non-operation signal when the operation switch is invalid.

[Effect]

Parameters to which specific values are given in correspondence with operation switches to be enabled are stored in a first memory.

Further, the state of the signal at the time of non-operation is stored in the second memory.

The operation signal is input manually and a predetermined calculation is performed based on the parameter stored in the first memory and the signal at the time of non-operation. As a result of this calculation, the operation signal of the operation switch set as valid by the parameter is output, but the operation signal of the operation switch set as invalid is output when the operation switch is not operated.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a partial configuration diagram of a PMC (programmable machine controller) to which the operation switch function selection method of the present invention is applied, and shows the input portion of operation signals. IO is an operation panel for operating machine tools,
There are operation switches 11-15. Operation switch 11-1
When 5 is operated, a predetermined digital signal is output.

20 is a PMC. Reference numeral 21 denotes a determination parameter, which stores determination parameters P given predetermined logical values, which will be described later, in correspondence with each of the operation switches 11 to 15.

When the power is turned on, first, the initial state signals of the operation switches 11 to 15, that is, the signals when not operated, are transferred to the initial state memory 23 via the input receiver 22', and the initial signal 1 is transferred to the initial state memory 23 via the input receiver 22'.
be memorized as

When any of the operation switches 11 to 15 is operated, an operation signal C is input to the determination means 24 via the input receiver 21. The determination means 24 converts the operation signal C into a determination parameter P.
and performs a logical operation with the initial signal I. With this logical operation,
If the operation signal C is an operation signal of an operation switch set as valid in parameter P, it will be output as is, but
If the operation signal of the operation switch is set to be invalid, the signal at the time of non-operation is output.

Note that the determination operation selection means 25 can select whether or not to perform the determination operation of the determination means 24 described above. This is determined by the values of parameters within the determining means 24. The parameters are arbitrarily set by the operator.

Next, the determination method will be specifically explained using an example. FIG. 2 is a schematic diagram of each signal in one embodiment of the present invention. In the figure, the determination parameter P is composed of 5 bits, and each address A1, A2, ---1---...
---A5 has operation switches 11 and 12 in order from the left.
, -...-1...-15 are stored. Note that the initial signal (2) and the operation signal C, which will be described later, are similarly composed of 5 bits, and correspond to the operation switches 11, 12, . . . , 15 in order from the left in the figure.

Here, the determination parameter corresponding to the operation signal of the operation switch or switch to be made valid is set to "1".

In this embodiment, the operation signals of the operation switches 11 and 12 are set to be valid, and the operation signals of the operation switches 13, 14 and 15 are set to be invalid.

Further, the initial signal (2) stored when the power is turned on is stored as rQJ for operation switches 11 and 15, and rlJ for operation switches 12, 13 and 14.

As for the operation signal C, only the operation signal of the operation switch 14 is ro.
J and other operation switches are all output in the logic state of trIJ.

Next, the above-mentioned determining means calculates the logical product of the determined parameter P and the operation signal C. As a result, only the logical values of the addresses corresponding to the operation switches 11 and 12 are r l J, which is the same as the operation signal C, and the other logical values are rOJ
becomes. Furthermore, the logical product E of the negative logical value of the determination parameter P and the initial signal I is calculated. * in the diagram represents negation. As a result, the logical values of the addresses corresponding to the operation switches 13, 14 and 15 become the value of the initial signal I.

Next, the logical sum F of the logical product and the logical product E is calculated, stored in the execution signal memory, and output as an internal signal of the PMC. As a result, the operation switch 11 and 12 which set the parameter P to "rl" output the operation signal C as it is, and the operation switch which set the parameter P to FOJ outputs the initial signal I.

FIG. 3 shows an overall configuration diagram of hardware for implementing the present invention. In the figure, the PMC 20 is the processor 2
6, a ROM 27, a RAM 28, and an interface 29 with the outside.

The ROM 27 contains a management program that controls the PMC 20.
Ladder programs etc. that control the machine are stored.

The RAM 28 stores input/output signals and various data. A machine and an operation panel are connected to the interface 29, and input signals (DI) and output signals (DO) are exchanged.

30 is a numerical control device (CNC), and only the processor 31 and shared RAM 32 are shown in the figure, and other elements are omitted. PMC20 and numerical control device 30
can exchange data with each other via the shared RAM 32.

Note that although the above description has been made using the operation switch of the PMC, the application of the present invention is not limited to this. Further, the number of operation switches can be increased or decreased as necessary.

[Effects of the Invention] As explained above, in the present invention, since the operation switch to be enabled can be selected by the parameter, there is no need to separate the operation switches with a protective cover or the like. In addition, since each operation switch can be enabled or disabled as desired, it is possible to respond flexibly even if the driving pattern etc. is changed.
