(Second embodiment)
Next, a second embodiment of the present invention will be described. In the following description, the same portions as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate.

  The difference between the controller 100 according to the second embodiment and the controller 1 according to the first embodiment is that the controller 100 has a module configuration as shown in FIG.

(controller)
The controller 100 includes a main module 200 that controls the control target device 80 in sequence, and a plurality of sub modules 300 that can communicate with the main module 200.

(Sub module)
The sub module 300 acquires an input operation of a user operation on the controller 100 as event data, and an I / O sub module 340 acquires control data output from the main module 200 to the control target device 80 as event data. And a sensor input sub-module 350 that acquires environmental state data from the environmental sensor 90.

  Each submodule 300 stores an internal clock 310 (310a, 310b, 310c) for measuring the internal time in the submodule 300, and a later-described submodule log 360 (360a, 360b, 360c) that is a log in the submodule 300. Log memory 320 (320a, 320b, 320c), and a defect detection unit 327 (327a, 327b, 327c) that is a defect detection means for detecting the occurrence of a defect.

  The internal time measured by the internal clock 310 is initialized (reset) when communication is performed with the main module 200 (see FIG. 8 described later). That is, the internal time measured by the internal clock 310 is an elapsed time from the last communication performed with the main module 200.

  Further, the defect detection unit 327 outputs defect detection data to the main module 200 when a defect is detected. Note that the input submodule 330 and the I / O submodule 340 also output defect detection data to the sensor input submodule 350.

(Input submodule)
The input submodule 330 creates display data based on the display control data output from the main module 200 and the environmental state data acquired by the sensor input submodule 350, and outputs the display data to the LCD panel 31. The input submodule 330 acquires the operation input data output from the setting button 32 as event data, and uses the internal time counted by the internal clock 310a at the time of acquisition as event acquisition time data, as shown in FIG. A submodule log 360a including event data (operation input data) and event acquisition time data is stored in the log memory 320a.

(I / O submodule)
The I / O submodule 340 acquires control data output from the main module 200 to the control target device 80 as event data. When the event data is acquired, the internal time counted by the internal clock 310b is set as event acquisition time data. As shown in FIG. 5, the submodule log 360b including event data (control data) and event acquisition time data is used. Is stored in the log memory 320b. The time when the control data of the I / O submodule 340 is acquired and the time when the setting (capability) of the control target device 80 is changed by the control data are the same time.

(Sensor input submodule)
The sensor input submodule 350 uses the internal clock 310c as a cycle timer, and acquires environmental state data from the environmental sensor 90 at predetermined time intervals timed by the internal clock 310c. Specifically, environmental state data is acquired from the environmental sensor 90 when a recording trigger is output from the internal clock 310c at predetermined time intervals. Further, the internal time counted by the internal clock 310c at the time of acquisition of the environmental state data is set as environmental state acquisition time data, and as shown in FIG. 5, the submodule log 360c including the environmental state acquisition time data and the environmental state data is included. Is stored in the log memory 320c.

  In the present embodiment, the recording trigger output from the internal clock 310c is output every 60 seconds under normal conditions and every 5 seconds under specific conditions. That is, when a transition is made from a normal time to a specific condition, the recording trigger output interval is changed from the 60-second interval to the 5-second interval.

  In this specific condition, when the state of the environmental test apparatus 50 is in a state set in advance by the user as a state where there is a high possibility that a failure will occur in the environmental test apparatus 50 (a predictable phenomenon occurs). In the environmental test apparatus 50 and when there is a problem that the user cannot predict (when an unpredictable phenomenon occurs).

  When the state of the environmental test apparatus 50 is in a state preset by the user that there is a high possibility that a failure will occur in the environmental test apparatus 50, as shown in FIG. Is within a predetermined range of the set environment (for example, when the temperature of the test chamber 51a approaches the set temperature and is around 5 ° C.), or when the capability of the control target device 80 is changed. That is, when the environmental state of the test chamber 51a is within a predetermined range of the setting environment, or when the ability of the control target device 80 is changed, there is a high possibility that a failure will occur in the environmental test apparatus 50. As described above, when the environmental test apparatus 50 is in a state where there is a high possibility of occurrence of a malfunction, the time interval for acquiring environmental state data is shortened in advance and stored in detail (higher recording density) as a log. Therefore, when a problem occurs, the cause of the problem can be identified more easily by checking this log. If the environment condition of the test chamber 51a deviates from the predetermined range of the setting environment, or if it has transitioned (returned) from a specific condition to a normal time, this transition or a predetermined time from the transition After (for example, after 3 minutes), the time interval of the recording trigger output from the internal clock 310c is returned from the 5 second interval to the 60 second interval.

  On the other hand, in the environmental test apparatus 50, when the malfunction which a user cannot predict has occurred, the power failure of the apparatus power supply of the environmental test apparatus 50, a voltage drop, external environment (for example, environmental When there is an abrupt change in the place where the test apparatus 50 is installed (room temperature or humidity), or there is external communication with another environmental test apparatus 50 via the communication control unit 25, interrupt control is generated in the main module 200, etc. There is. As described above, since the environmental state data can be stored in detail as a log when a problem occurs, the cause of the problem can be identified more easily by checking this log.

  The sensor input submodule 350 includes a ring memory 325 having a ring structure, and as shown in FIG. 7, a time interval shorter than a predetermined time interval (60-second interval) measured by the internal clock 310c. To get environmental status data. Specifically, the internal clock 310c outputs a small recording trigger every 5 seconds, and acquires environmental state data from the environmental sensor at the time of output. Further, the internal time measured by the internal clock 310c at the time of acquisition is set as environmental state acquisition time data, and a small cycle log including the environmental state acquisition time data and the acquired environmental state data is recorded in the ring memory 325. When the failure detection unit 327 detects a failure in any of the submodules 300, the sensor input submodule 350 transmits the small cycle log stored in the ring memory 325 to the main module 200.

(Main module)
The main module 200 includes a real-time clock 23, a main memory 24 in which logs of the entire environmental test apparatus 50 are stored, a communication control unit 25 that is a communication control unit capable of communicating with other environmental test apparatuses 50 via a network, and a controller. A macro generation unit 27 which is a macro generation unit capable of generating a macro capable of reproducing the operation input procedure.

  The communication control unit 25 controls communication between the main module 200 and the sub module 300. Further, the communication control unit 25 communicates with the communication control unit 25 of the other environmental test apparatus 50 via the network, so that the environmental test apparatus whole log 240 stored in the main memory 24 and the controller 100 described later are stored. It is possible to send and receive macros that can reproduce the operation input procedure and to remotely operate the controller 100 of another environmental test apparatus 50. As a result, the entire environmental test apparatus log 240 stored in the main memory 24 of the controller 100 of the environmental test apparatus 50 installed in the remote place can be acquired. As a result, the environmental test apparatus installed in the remote place is obtained. The cause of the failure in the entire log 240 can be analyzed without going to the installation location. Further, since the controller 100 can be remotely operated using the entire environmental test apparatus log 240, remote maintenance can be performed from a remote location.

  Furthermore, the communication control unit 25 can exchange macros that can reproduce an operation input procedure of the entire environmental test apparatus log 240 and the controller 100 described later with the external storage medium 26.

  The macro generation unit 27 can read event data (operation input data) received from the input submodule 330 and event acquisition adjustment time data, which will be described later, stored in the main memory 24 and reproduce the operation input procedure of the controller 100. Macros can be generated. As a result, it is possible to share the know-how, skills, etc. of operation of the environmental test apparatus 50 possessed by each user.

  As a method for generating an operation macro, for example, necessary data is extracted from the entire environmental test apparatus log 240 stored in the main memory 24, and the extracted data is edited by an editing device such as a personal computer. There is a method of generating an operation macro as an executable program. The operation macro generated in this way is stored in the main memory 24 and can be executed by a user operation input. Note that the operation macro itself may be incorporated into the sequence program of the main module 200.

  In this embodiment, the event data stored in the main memory 24 and event acquisition adjustment time data described later are read to generate a macro. However, the event stored in the log memory 320 a of the input submodule 330 is used. Data and event acquisition time data may be read to generate a macro.

  The main module 200 stores a sequence program, creates control data based on the sequence program and data received from each submodule 300, and controls the control data via the I / O submodule 340. Output to the target device 80. Further, display control data including information to be displayed on the LCD panel 31 is output to the input submodule 330.

  Further, the main module 200 outputs a log transmission request to each submodule 300 and receives the submodule log 360 when there is a margin in processing (task idle time). When the main module 200 receives the submodule log 360, the main module 200 receives the reception time data that is the current time measured by the real-time clock 23 at the time of reception, the transmission internal time data attached to the submodule log 360, and the submodule log 360. Using the event acquisition time data or environment state acquisition time data included in the module log 360, event acquisition adjustment time data based on the real time clock 23 or environment state acquisition adjustment time data based on the real time clock 23 is calculated.

  Hereinafter, a method for calculating the event acquisition adjustment time data using the event data included in the submodule log 360a received from the input submodule 330 will be specifically described with reference to FIG. As shown in FIG. 8, the main module 200 receives from the input submodule 330 the submodule log 360 a to which the transmission internal time data is attached. The internal time data at the time of transmission is the internal time measured by the internal clock 310a at the time of transmission to the main module 200 in the input submodule 330.

  First, the main module 200 subtracts the value of the event acquisition time data from the value of the internal time data at the time of transmission, and the time elapsed from the time when the event data was acquired by the input submodule 330 to the time of transmission of the submodule log 360a (Hereinafter, elapsed time) is calculated. Next, the reception time of the sub module log 360a in the main module 200 and the transmission time of the sub module log 360a in the input sub module 330 are considered to be the same time, and a value obtained by subtracting the elapsed time from the value of the reception time data is Event acquisition adjustment time data. By doing in this way, the event acquisition time data of the submodule log 360a can be used as event acquisition adjustment time data based on the real time clock 23.

  Note that a method for calculating event acquisition adjustment time data using event data included in the submodule log 360b received from the I / O submodule 340, and an environment included in the submodule log 360c received from the sensor input submodule 350. The method for calculating the environmental condition adjustment time data using the state data can be calculated by the same method as described above, and thus the description thereof is omitted.

  The event acquisition adjustment time data calculated in this manner is associated with the event data and stored in the main memory 24 as event log data 241 as shown in FIG. Similarly, the environmental state acquisition adjustment time data is stored in the main memory 24 as environmental state log data 242 in association with the environmental state data.

  Further, the event log data 241 includes environmental state data corresponding temporally to the event data included in the event log data 241. The environmental state data corresponding temporally to the event data is obtained using the event acquisition adjustment time data and the environmental state acquisition adjustment data. Specifically, as shown in FIG. 9, the environmental condition acquisition adjustment data that is closest in time to the event acquisition adjustment time data is obtained, and the environmental condition data corresponding to this environmental condition acquisition adjustment data is stored in the event log. Include in data. By doing in this way, even when the environmental state data is not acquired at the same time as the acquisition time of the event data, it is possible to associate the event data with the environmental state data.

  In addition, as shown in FIG. 10, the values of the environmental state data included in the arbitrary environmental state log data 242 stored in the main memory 24 are the environments immediately before and after the environmental state acquisition adjustment time data. When the value of the environmental status data included in the status log data 242 is substantially the same, except when the environmental status data included in the arbitrary environmental status log data 242 is temporally associated with the event data. The environmental status log data 242 is deleted from the main memory 24. By doing so, in the period when the environmental state of the environmental test apparatus 50 is stable and the value of the environmental state data does not change, the first and last environmental state log data 242 of this period are left and other The environmental state log data 242 will be deleted. As a result, the amount of data stored in the main memory 24 can be reduced, and the storage capacity of the main memory 24 can be saved. Note that “substantially the same” does not mean that the values of the environmental state data are completely the same, but as long as it is within an error range allowed by the user as shown in FIG. To do. Further, in FIG. 10, for convenience of explanation, the entire environmental test apparatus log 240 in which the event log data 241 and the environmental state log data 242 are collected is illustrated.

(Processing of the controller)
Next, the processing operation of the controller 100 will be described with reference to FIGS.

(Main module operation)
First, the processing operation of the main module will be described with reference to FIG.

  When the power supply of the environmental test apparatus 50 is activated, the main module 200 stores the current time measured by the real-time clock 23 in the main memory 24 as activation time data and performs initial communication with each submodule 300 (A1). ).

  Next, the main module 200 determines whether or not there is a margin for processing (whether or not it is a task idle time) (A2). If it is determined that there is not enough processing (A2: NO), the control target device 80 is subjected to sequence control (A3), and the process proceeds to A6.

  On the other hand, when it is determined that there is a margin in processing (A2: YES), a log request is transmitted to each submodule 300 (A4). Next, the entire environmental test apparatus log 240 (event log data 241 and environmental status log data 242) is generated from the submodule log 360 received from each submodule 300 and stored in the main memory 24 (A5). At this time, environmental state data corresponding to the event data in time is obtained, and the obtained environmental state data is included in the event log data 241 and stored. When the process of A5 is completed, the process proceeds to A6.

  In the process of A6, it is determined whether failure detection data is received from any of the submodules 300. If it is determined that the defect detection data has not been received (A6: NO), the process proceeds to A2.

  On the other hand, when it is determined that the defect detection data has been received (A6: YES), the main module 200 receives the small cycle log from the sensor input submodule 350 and transmits a log request to the submodule 300. The reception of the submodule log 360 from the submodule 300 and the storage of the entire environmental test apparatus log 240 in the main memory 24 similar to the processing of A5 are continued for a predetermined time (A7). Thereafter, a recording stop command is transmitted to the submodule 300, and the recording operation to the main memory 24 of the entire environmental test apparatus log 240 is stopped (A8), and this processing operation is terminated. As described above, the recording operation of the environmental test apparatus entire log 240 in the main memory 24 is stopped after a predetermined period has elapsed since the occurrence of the malfunction, so that the controller 100 can be protected from the malfunction. The predetermined time is a time when the submodule log 360 necessary for specifying the cause of the malfunction is received from the submodule 300, and the entire environmental test apparatus log 240 generated using the submodule log 360 is stored in the main memory 24. This is the time it takes to memorize.

(Processing of input submodule)
Next, the processing operation of the input submodule 330 will be described with reference to FIG.

  The input submodule 330 initializes the internal time measured by the internal clock 310a during initial communication from the main module 200 (B1). Next, it is determined whether or not operation input data has been acquired from the setting button 32 (B2). When it is determined that the operation input data has been acquired (B2: YES), the internal time counted by the internal clock 310a at the time of acquisition is set as event acquisition time data, and event data (operation input data), event acquisition time data, Is stored in the log memory 320a (B3), and the process proceeds to B6.

  On the other hand, if it is determined that the operation input data has not been acquired (B2: NO), it is determined whether the defect detection unit 327a has detected a defect (B4). If the defect detection unit 327a determines that no defect has been detected (B4: NO), the process proceeds to B6.

  On the other hand, when the defect detection unit 327a determines that a defect has been detected (B4: YES), the input submodule 330 transmits defect detection data to the main module 200 and the sensor input submodule 350 (B5). , B2 is started.

  In the process of B6, the input submodule 330 determines whether or not a log request has been received from the main module 200. If it is determined that the log request has not been received (B6: NO), the process proceeds to B8.

  On the other hand, if it is determined that the log request has been received (B6: YES), the input submodule 330 transmits the submodule log 360a stored in the log memory 320a to the main module 200 (B7). Move on to processing. The sub module log 360a transmitted to the main module 200 may be deleted from the log memory 320a. Further, when the input submodule 330 receives a log request and there is not enough processing (not a task idle time), the next time the log request is received from the main module 200, the submodule log 360a may be transmitted.

  In the process of B8, it is determined whether or not a recording stop command is received from the main module 200. If it is determined that the recording stop command has not been received (B8: NO), the process proceeds to B2.

  On the other hand, if it is determined that a recording stop command has been received (B8: YES), acquisition of operation input data from the setting button 32 is stopped, and recording of the submodule log 360a to the log memory 320a is stopped. (B9) This processing operation ends.

(Processing operation of I / O submodule)
As shown in FIG. 13, the processing operation of the I / O submodule 340 is substantially the same as the operation of the input submodule, and the operation input data output from the setting button 32 is transferred from the main module 200 to the control target device 80. Since the internal clock 310a is replaced with the internal clock 310b, the log memory 320a is replaced with the log memory 320b, the submodule log 360a is replaced with the submodule log 360b, and the defect detector 327a is replaced with the defect detector 327b. Is omitted.

(Processing of sensor input submodule)
Next, the processing operation of the sensor input submodule 350 will be described with reference to FIG.

  The sensor input submodule 350 initializes the internal time measured by the internal clock 310c during initial communication from the main module 200 (D1). Next, it is determined whether or not a recording trigger output from the internal clock 310c at every predetermined time interval (normal: 60 seconds, specific conditions: 5 seconds) is output (cycled up). (D2). When it is determined that the recording trigger has been output (D2: YES), the internal time measured by the internal clock 310c when the recording trigger is output (when the environmental state data is acquired) is used as the environmental state acquisition time data. The submodule log 360c including the environmental status data acquired from the environmental sensor 90 and the environmental status acquisition time data when the trigger is output is stored in the log memory 320c (D3), and the process proceeds to D8. Note that the internal clock 310c outputs a small recording trigger every 5 seconds, and the internal time measured by the internal clock 310c at the time of outputting the small recording trigger (when acquiring the environmental state data) is the environmental state acquisition time data. When the small recording trigger is output, a small cycle log including the environmental state data acquired from the environmental sensor 90 and the environmental state acquisition time data is stored in the ring memory 325.

On the other hand, if it is determined that the recording trigger is not output (D2: NO), the state of the environmental test apparatus 50 is in a state where there is a high possibility that a failure will occur in the environmental test apparatus 50 (or prediction is possible). (D4). If it is determined that a failure is likely to occur or a predictable phenomenon has occurred (D4: YES), the time interval of the recording trigger output by the internal clock 310c is changed to 5 seconds. (D5) The process proceeds to D8 .

  On the other hand, when a predictable phenomenon has not occurred (D4: NO), it is determined whether or not a failure that cannot be predicted by the user has occurred in the environmental test apparatus 50 (D6). Specifically, when the failure detection unit 327c determines that a failure has been detected, or when it has been determined that failure detection data has been received from another submodule 300, it is determined that a failure has occurred in the environmental test apparatus 50. To do. In other cases, it is determined that no problem has occurred in the environmental test apparatus 50.

  If it is determined that a failure has occurred (D6: YES), the time interval of the recording trigger output by the internal clock 310c is changed to 5 seconds, and the small cycle log stored in the ring memory 325 is stored in the main module 200. Transmit (D7) and move to processing of D2. On the other hand, when it is determined that no defect has occurred (D6: NO), the process proceeds to D8. If the defect detection unit 327c determines that a defect has been detected, the defect detection data is transmitted to the main module 200.

  In the process of D8, the sensor input submodule 350 determines whether or not a log request has been received from the main module 200. If it is determined that a log request has not been received (D8: NO), the process proceeds to D10.

  If it is determined that the log request has been received (D8: YES), the sensor input submodule 350 transmits the submodule log 360c stored in the log memory 320c to the main module 200 (D9), and the process of D10 Move on. The submodule log 360c transmitted to the main module 200 may be deleted from the log memory 320c. Also, when the sensor input submodule 350 receives a log request and there is not enough processing (not a task idle time), the submodule receives the log request from the main module 200 next time. The log 360c may be transmitted.

  In the process of D10, it is determined whether or not a recording stop command is received from the main module 200. If it is determined that the recording stop command has not been received (D10: NO), the process proceeds to D2.

  On the other hand, if it is determined that the recording stop command has been received (D10: YES), the acquisition of the environmental state data from the environmental sensor 90 is stopped, and the recording of the submodule log 360c in the log memory 320c is stopped. (D11), this processing operation ends.

  There is a debugger using an editing device as a debugger for an environmental test device. The debugger using the editing device is a PLC editing device (such as a personal computer) that stores the sequence program and the entire environmental test device log 240 stored in the main memory 24. Based on this sequence program, the environmental test is performed. This is a debugger that confirms the entire apparatus log 240 by executing steps. The debugger uses the editing device to convert the event data and environmental state data of the entire environmental test apparatus log 240 stored in the main memory 24 into the real-time clock 23 using the event acquisition adjustment time data and the environmental state acquisition adjustment time data. In order of storage (acquisition) based on the above, and step by step continuously without considering the time interval of acquisition adjustment time data with temporally adjacent event data or environmental state data, This is to confirm the operation. The debugger using this editing apparatus is very simple and does not relate to the execution time, so that the operation of the sequence program can be confirmed in a very short time.
