Description

[Detailed description of the invention] The present invention relates to a programmable oscilloscope.

In this specification, a programmable oscilloscope refers to the selection of the channels necessary for waveform display on the oscilloscope main body, the setting of the trigger mode, the setting of the measurement range, the positioning of the reference mechanism of the displayed waveform on the vertical axis, and the vertical axis. Sensitivity setting, horizontal axis time value setting (%) 9G polarity setting The setting contents of each setting section are stored in advance in correspondence with the waveform to be observed, and the setting contents are read out and read out in correspondence with the observed waveform. This refers to an optical scope that displays waveforms by setting each setting section according to the specified settings.

In addition, the settings for each of the above settings can be made using the programmer tool, the setting device corresponding to each setting section provided on the sysyscope, or the knobs of each setting section on the main body of the oscilloscope, which constitutes a part of the programmable oscilloscope. is set, and the position of the setting device or knob is read and stored in the storage device.

The setting contents corresponding to each setting section are referred to as setting data in this specification. Also, perform this setting operation for each waveform to be observed and store it in the storage device.
In this specification, all setting data for one waveform to be observed is referred to as a program step, f. Therefore, a plurality of program steps consisting of a plurality of setting data are stored in the storage device, and normally several dozen program steps are stored.

On the other hand, in order to identify each program step, f, for example, a number is attached corresponding to each program step,
Program steps are read from the storage device by specifying the number mentioned above. By specifying this number, the program step is stored and the program step is read from the storage device according to the observed waveform. Waveform observation is performed by selectively recalling the selected program step, setting each setting section, and then observing the waveform.For example, when observing the same waveform on multiple production lines, conventional Regarding scopes, the programmer pull oscillator installed in each production line had the disadvantage that the settings for the four scopes had to be done independently, requiring duplication of time to set the program steps. In view of the above, the invention is - Progera! At the same time as setting the program steps of Bluo and Ciroscope, other Grogramma Pluo,
It is an object of the present invention to provide a programmable ascilloscope that allows the same address specification to be made to a sequence control device or the like that controls a controlled object using information read from a cilloscope or a storage device.

The present invention will be explained below with reference to Examples.

FIG. 1 is a block diagram showing the main parts of an embodiment of the present invention.

1 is the main body of the ship scope that displays waveforms, 2 is the storage device in which program steps are stored, and 3 is the number assigned to the program step to read the selected program step from the storage device 2. By setting by a control device (not shown), the address of the storage device storing the program step corresponding to the number + register or address counter (
Hereinafter, the oscilloscope body 11, the storage device 2, and the register 3 constitute the -llS' of a conventional programmable oscilloscope, and the program step numbered in the register 3 is stored. When the data is read out from the device 2, each setting section of the oscilloscope body 1 is set according to the setting data constituting the read program steps.

In this embodiment, between the register 3 and the storage device 2,
Output of register 3 and independently set register 4
A selector 5 inputs the output of the selector 5 and selects and outputs one of the inputs, a buffer 6 receives the output of the selector 5 as an input, and converts it into a binary signal as an output tube input of the node 7a 6. It is connected to the converter 7 which outputs the data to the storage device 2 through t. Table registers 3 and 4 are arranged to produce an output in a binary coded 10-adic code. The converter 7 is therefore a binary coded IO code/binary code converter.

The output of the buffer 6 is also outputted to another programmable oscilloscope as a signal in place of the output signal of the register 4.

In this embodiment configured as above, if the input from the register 3 is selected by the selector 5 according to the island select signal,
The output of the register 3 is inputted to the converter 7 via the selector 5 and the buffer 6, converted into a binary code by the converter 7, and applied to the storage device 2. On the other hand, the output of buffer 6 is applied to other programmable oscilloscopes and program steps specified by register 3 are output from the memory of other programmable oscilloscopes. , is output to the oscilloscope body that forms part of another programmable oscilloscope.

Also, when the selector 5 selects the input from the register 4 by the select signal, the output from the register 4 is similarly converted to a binary code by the converter 7 and applied to the storage device 12. , the program status specified by the register 4 from the storage device 2 is output to the oscilloscope main body l, and at the same time the other programs
The program step specified by the register 4 is output from the storage device of the scope to the other programmable oscilloscope body 1.

Therefore, it is possible to select program steps for the programmable ascilloscope as well as for other programmable ascilloscopes.

When selecting a program step using register 4, select the program step specified by register 3.
Next, other embodiments of the present invention will be described.

FIG. 2 is a block diagram showing main parts of another embodiment of the present invention.

In another embodiment of the present invention, the programmable ascilloscope according to the embodiment of the present invention shown in FIG.
As shown in FIG. 2, between the register 4 and the selector 5, the output of the child circuit 10 and the latch circuit 1O is inputted to be latched by the output rough lock pulse CK of the register 4, and output as is. The output is compared with the output of the setting device 15, and when the output of the latch circuit 10 is equal to the output of the setting device 15, the output is output to the upper limit comparator 17 (no-goo) 17.The output of the upper limit comparator 11 is input and output as is. and a lower limit comparator 1 which compares the output of the upper limit comparator 11 with the output of the setter 16 and generates an output to the node f-) 17 when the output of the upper limit comparator 11 is less than the output of the setter 16.
2 and the output of the output tube and dart 18 of the lower limit comparator 12 are connected to the latch circuit 13 which outputs to the selector 5. The output of Noah r-) 17 is applied with black and cross CK as well as AND dirt 1BK.

The setter 15 sets the program step of the storage device 2, and the upper limit of the storage address of 'f' is stored in the setter 16.
It is set in O-adic code.

Therefore, the output of the register 4 is latched in the child circuit IO, and is compared with the set value of the setter 15 in the upper limit comparator 11, and is compared to see if it is less than a certain value set by the setter 15tC, and then the lower limit The comparator 12 compares the set value of the setter 16 with the set value of the setter 16 to determine whether the value is greater than or equal to the value of the setter 16.

Therefore, when the output of the child circuit IO is below the set value of the setter 15 and above the set value of the setter 16, the latch circuit 13 outputs a clock pulse CK. is checked and output to the selector 5.

Further, when the output of the latch circuit 10 exceeds the set value of the setter 15, the upper limit comparator 11 outputs an output to the far gate 17, and this output is applied to the AND gate 18, and the AND? -) Close the dart of 18 and goo) Is 18 a clock tsuelus CK? No output, 2) The output of the child circuit 13 is outputted via the lower limit comparator 12, 2) The output of the child circuit 1O is not latched, and the output of the child circuit 13 is below the setting value of the setter 15. When is less than the set value of the setter 16, the lower limit comparator 12 outputs an output to the Noah ff-) 17, this output is applied to the AND gate 18, and the dart of the AND f-) 18 is closed and the AND r-) 18 is Clock Tsutsurus C
1l is not output, and the child circuit 13 does not latch the output of the latch circuit 16 that is output via the lower limit comparator 12.

Therefore, if the output of the register 4 is not more than the setting value of the setting device 15 and is not more than the setting value of the setting value 16, the output can be output to the selector 5 only when the output value of the register 4 is less than the setting value of the setting device 16. Even if it is set to a value less than the setting value of the setting device 15, it will not be output to the selector 5, making it possible to avoid erroneous operation.

In each of the above embodiments, the case where a binary coded decimal code is used has been explained, but there is no need to limit it to this.
The evolved IO-adic code can be set with the smallest number of v4 codes.

First, in each of the above embodiments, when specifying the program step of another programmable ascilloscope by the program step of the - programmable ascilloscope, it was explained to the operator that the program step of the - programmable ascilloscope is specified. By specifying four scope program steps,
It can also be used to specify the address of a sequence control device or the like that controls a controlled object based on the information read from the storage device.

As described above, according to the present invention, it is possible to simultaneously set the program steps of the - programmable or ascilloscope and to set the same program steps for the other programmable or ascilloscopes.

Further, when making the settings, it is possible to avoid erroneous operations when an address in the storage device where no program step is stored is specified.
