[0002]
[Prior art]
This type of prior art is disclosed in Japanese Patent Application Laid-Open No. 3-14041 as “program execution time measuring method of programmable controller”.
[0003]
FIG. 25 is a block diagram showing an embodiment of the present invention. The program detector 101 detects the start and end of a program when the program is executed in the programmable controller 100 via the common bus 104, and the program type, its generation time, Are sequentially stored in the trace memory 102, and when necessary, the program type stored in the trace memory 102 and the generation time thereof are associated with each other and displayed on the CRT display 103.

[0026]
When the initialization of each processing unit is completed, the control unit 5 edits the initialization response status frame and notifies the status transmission unit 2 of a status transmission instruction. The status transmission unit 2 transmits the initialization status to the communication control device (204 in FIG. 2, step A2 in FIG. 6), and completes the processing corresponding to the initialization command.
[0027]
Further, when recognizing the measurement registration command (207 in FIG. 2, step 6 in FIG. 5), the control unit 5 notifies the storage processing unit 8 of a command parameter storage instruction.

[0031]
When the control unit 5 recognizes the measurement cancellation command accompanied by the designation of the number of the measurement registration command (213 in FIG. 2 and step 6 in FIG. 5), it notifies the storage processing unit 8 of a command parameter cancellation instruction. In FIG. 2, the number # 2 of the measurement registration command is designated. The storage processing unit 8 determines an area to be canceled using the first parameter of the measurement cancellation command as a search key, and deletes, updates, and stores it from the measurement management information stored in the memory 13 (steps C1 and C2 in FIG. 7). .

The status transmission unit 2 transmits the function stop status to the communication control device (218 in FIG. 2, step D3 in FIG. 7).
[0034]
When the control unit 5 recognizes the print command (219 in FIG. 2 and step 6 in FIG. 5), it reads out the measurement management information stored in the memory 13 from the storage processing unit 8 and sends it to the external device processing unit 9. A print instruction is notified (steps G1 to G4 in FIG. 8). The external device processing unit 9 activates the printer interface unit 14 and prints the measurement management information. The control unit 5 edits the print status frame and notifies the status transmission unit 2 of a status transmission instruction. The status transmission unit 2 transmits the print status to the communication control device (220 in FIG. 2, step G5 in FIG. 8).
[0035]
Note that the Ver request (processing time measuring device version notification request) command, clock data transmission request command, PC (personal computer) output command, and FD command output as a result of command analysis in step 6 in FIG. Are omitted, but are processed by the respective flowcharts in the same manner as the command processing described above.
[0036]
In each of the above operations, the control unit 5 notifies the operation / display processing unit 7 of a state display instruction indicating the operation status, and performs display on the display unit 12.

FIG. 20 is a time chart showing a time-series change in the signal logic value for each signal in FIG.
[0038]
Next, a second embodiment of the present invention will be described with reference to the drawings.
[0039]
Referring to FIG. 21, the second embodiment of the processing time measuring device of the present invention does not perform transmission / reception of commands and status with the communication control device as compared with the embodiment shown in FIG. 1. The measurement signal receiving unit 21 has the configuration and functions of the signal monitoring unit 4 shown in FIG. 1, and the control unit 22 has the configurations and functions of the measurement signal processing unit 6 and the timer processing unit 10. The storage processing unit 25 has a function of giving a control instruction and output data to the external device processing unit 26.
[0040]
The measurement signal receiving unit 21 monitors the states of all signals input from the communication control device and notifies the control unit 22 of signal state information.
[0041]
The control unit 22 stores all signal states notified from the measurement signal receiving unit 21. When a change in the signal state is found, the control unit 22 acquires year / month / day / hour / minute data from the clock 33, and from the timer / counter 23, Second microsecond data is acquired and a storage instruction is notified to the storage processing unit 25.
[0042]
When the operation / display processing unit 24 detects that the input of the key unit 27 is an external device output designation, the operation / display processing unit 24 notifies the control unit 22 of the instruction. The control unit 22 notifies the storage processing unit 25 of an output instruction. Upon receiving this instruction, the storage processing unit 25 directly outputs the stored measurement information to the external device processing unit 26.
[0043]
Next, specific examples will be described with reference to flowcharts. FIG. 22 is a flowchart of the processing time measuring apparatus. When the processing time measuring apparatus is turned on, the processing time measuring apparatus executes an initial setting process (step 71) and a mode setting process (step 72), and a signal measuring process (step 73). And input monitoring with key designation are started (step 74).
[0044]
In signal measurement processing, the initial signal levels of all input signals at power-on are input and stored, the subsequent signal levels are monitored, and the signal level changes using a clock and timer counter for the duration of each signal state. The measured time information is measured and stored in the memory 29.
[0045]
Further, when the measurement registration designation is received by the key designation, the measurement of the corresponding signal is canceled to give priority to the measurement by the key designation. Each designation of measurement name code, signal designation, measurement type and signal logic is performed from the key designation. The measured and stored information is output from the memory 29 to the designated external device by key designation. Similarly, each function selection such as initialization, measurement cancellation, and function cancellation can be selected and executed by key designation, and the detailed flow thereof is as shown in FIGS.
[0046]
As described above, in the first embodiment and the second embodiment, the case where the communication control device and the processing time measurement device transmit and receive commands and statuses and the case where they are not transmitted and received have been described. An embodiment in which the processing time is measured without receiving only a command from the communication control device is also conceivable.
[0047]
【The invention's effect】
A first effect of the present invention is that commands and statuses of an external device and a processing time measuring device are defined, and a hardware signal to be measured can be measured with instructions from the external device. The reason is that since the processing time measuring device measures the time of the active section of the hardware signal, it is not necessary to fix each signal between the external device and the processing time measuring device.
[0048]
The second effect is that the processing time can be measured by each combination of the processing time of the program and the hardware signal or device function. The reason is that not only the processing time of the program itself, but also the external device assigns the software processing contents, device functions or hardware output signals in advance for each hardware signal to be measured. This is because the processing time and timing relation between the program execution time and the signal output from the hardware as a result of the program control can be measured.
[0049]
The third effect is that a measurement method can be designated for each signal. The reason is that the measurement type and signal logic are defined in the parameters associated with the command and correspond to the waveform pattern of the hardware signal.
[0050]
Furthermore, the fourth effect is that the measured result is stored as the time when each signal changes, and can be output to a designated external device. The reason is that it has a clock, a timer / counter, a memory, and an external device processing unit.
