Abstract

(57) [Summary] [Purpose] Even if the counter is reset due to an operation error, it is possible to restore the counting state before the reset and perform counting operations from that count value. [Structure] When the counters CT1 to CTn are reset, the counters CT1 to CTn are reset in the control unit CC.
The reset count value of the counter is read from the storage unit CM, and the counter CT1 to
Controls the counter operation of CTn.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is equipped with multiple channel counters, and the counting operation of each counter is individually controlled. This invention relates to a counter device that can be controlled separately.

0002

[Conventional technology]

Generally, in a counter device, the counter can be reset to zero.

0003

[Problem that the idea aims to solve]

In the case of a counter with multiple channels, the counter may not need to be reset due to an operational error etc. There is a very high possibility that the counter will be reset.

0004 However, once the count value is reset in this way, it cannot be reset. Since the count value at the point of time is not memorized mechanically or electronically, the counter device itself However, it was impossible to restore the original count value.

[0005] Therefore, in this invention, if the counter is reset due to an operational error, etc. Even if the count value is reset, the count status will be restored to before the reset, and the count will start from that count value. The purpose is to make it possible.

[0006]

[Means to solve the problem]

The counter device of the present invention has multiple channel counters and each counter A storage section that stores the reset count value and a recovery input for any counter. Reads the reset count value corresponding to the arbitrary counter from the memory in response to the force. At the same time, the count operation of the corresponding arbitrary counter is read out from the reset counter. The present invention is characterized in that it includes a control section that performs control based on the count value.

[0007]

[Effect] For example, if a counter is reset due to an operation error, the reset counter can be reset. When counting from the set count value, the control section Reads the reset count value of the reset counter from the memory, and The counter operation of the counter is controlled from the count value.

[0008]

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0009] FIG. 1 is a block diagram of the main parts of a counter device according to an embodiment of the present invention. , counters CT1 to CTn each correspond to channels 1 to n. are numbered and each counts the count input individually. At the same time, the count output is output to the corresponding load.

0010 A storage unit CM consisting of a RAM etc. stores current data from each counter CT1 to CTn. input the count outputs and use these as the reset count value to the corresponding predetermined address. Save it in response. This storage operation is performed according to a storage command from the control unit CC. . The counter selection section CS is provided by each of the counters CT1 to CTn. Selectively output count output. This selection operation follows the selection command from the control unit CC. It is done. The display unit DU displays the counter provided via the counter selection unit CS. Display the output. This display operation is performed according to a display command from the control unit CC. . The control section CC is composed of a microcomputer, and the counter selection section C S has a selection command, storage part CM has a storage command, display part DU has a display command, and the counter A count control command is output to each of the controllers CT1 to CTn. Each command is counter selection input, re-monitor input, reset input, etc. given by the operation. Based on.

[0011] Here, the counter selection input is for each counter C from channel 1 to channel n. This is an input to select any one of T1 to CTn, and the re-monitor input is reset. The counting operation of each counter CT1 to CTn when it is alone without any input is as follows. Continue as is, but input to display the reset count value on the display unit DU. When combined with the reset input, the counter is counted from the reset count value. This is the input for operating the mount. The re-monitor input and reset input are This corresponds to the recovery input referred to in the scope of the patent registration request.

0012 To explain re-monitoring and reset input in more detail, the control unit CC When only the re-monitoring input is given, the control unit CC responds to this re-monitoring input. Reset count value of the counter of the number currently displayed on the display unit DU. At the same time as reading from the memory section CM by specifying the address, Display the count value on the display unit DU. In addition to the re-monitor input, the control unit CC When there is a cut input, the number displayed on the display unit DU will be displayed in response. Reads the reset count value of the counter from the memory CM and resets it. The counter is operated to count from the cut count value.

[0013] In addition, there is a counter selection input for the re-monitor input and reset input mentioned above. , the control unit CC selects the counter whose number corresponds to the counter selection input. The display of the reset count value on the display unit DU and the reset count value control the counting operation.

[0014] The operation of the control unit CC will be explained according to the flowchart of FIG.

[0015] In step n1, each counter is The counters CT1 to CTn are operated as counters, and the count value is displayed on the display D. While displaying it on U, perform processing such as outputting the count output to the load. . In step n2, if there is a re-monitoring input, the process moves to step n3. In step n3, the re-monitor processing mode is entered, and in step n4, the current display is The reset count value of the counter that is currently displayed is displayed on the display unit DU.

[0016] In step n5, if there is a counter selection input, the process moves to step n7, Add 1 to the currently displayed counter number, return to step n4, and + Performs re-monitor display processing of the counter that has been set to 1.

[0017] In other words, when only re-monitoring input is required, the counter displayed on the display unit DU In addition to displaying the reset count value and re-monitoring input, there is a counter selection input. and the reset count value of the counter of the number corresponding to that counter selection input. Display.

[0018] Next, if there is no counter number input in step n4, proceed to step n6. Transition.

[0019] In step n6, it is determined whether there is a reset input, and the reset input is determined. If there is power, the relevant counter is reset from the reset count value re-monitored in step n8. Make the data count.

[0020] In other words, when there is a reset input, the number of counters that were reset due to an operation error is If a number is specified, resets the counting operation of the counter for that number. control from the count value.

[0021] In this way, in this example, the counter reset due to an operational error can be controlled from the reset count value.

[0022]

[Effect of the idea]

As explained above, in the counter device according to the present invention, the counter can be reset. In this case, the control unit reads the reset count value of that counter from the storage unit. and control the counter operation of the counter from the read reset count value. Even if the counter is reset due to an operational error, the counter will remain as it was before the reset. It is possible to restore the count state and start counting from that count value.
