Hereinafter, the processing from when the motion system is activated and the initialization process of the motion controller is executed until the trigger alarm type and the trace data type are automatically set will be described in order with reference to FIGS. To do.
First, in step ST1000, the device configuration information collecting unit 100 is executed to acquire the device configuration information on the motion network 5 through the motion network 5, and the device configuration information held in the device configuration information holding unit 106 is updated.
Next, in step ST1001, the model information collecting unit 101 is executed for the node # 2i, the model information is read out from the model information holding unit 201i of the control target device 2i through the motion network 5, and held in the all device model information holding unit 107. Update all device model information.
In step ST1002, based on the number of nodes acquired in step ST1000, step ST1001 is loop-executed for the number of nodes.
Next, in step ST1003, the control program selection unit 102 is activated. In step ST1003, the database for determination is based on the device configuration information acquired and updated in steps ST1000 to ST1002 and held in the device configuration information holding unit 106 and all device model information held in all device model information holding unit 107. A control application file name is selected from 108.
Next, in step ST1004, the alarm trace data table selection means 103 is activated, and the alarm trace data table type is specified from the alarm trace data table type determination table 109 based on the control application file name selected in step ST1003. To do.
When the alarm trace data table type can be normally acquired from the alarm trace data table type determination table 109 in this way, the alarm trace data table acquisition unit 104 is activated in step ST1005.
In step ST1500, the alarm trace data table acquisition unit 104 first transmits a table request Treq to the server 4, and requests a file corresponding to the alarm trace data table type acquired in step ST1004. Upon receiving this, the alarm trace data table transmission means 400 in the server 4 reads out the file data corresponding to the specified alarm trace data table type from the various alarm trace data table storage areas 401 and returns it as a table response Tans. . The alarm trace data table acquisition means 104 waits for reception of this table response Tans in step ST1501, and if received, stores the received data in the alarm trace data table 110 in the motion controller 1 in step ST1502.
Next, in step ST1006, the trace data setting unit 105 is activated. First, in step ST1600, it is checked whether the alarm type of the trace data setting condition 111j held in the trace data setting condition holding unit 111 is Null. In the case of Null, in step ST1603, the alarm type and the trace data type are stored in the trace data setting condition of the trace data setting condition holding unit 111j. If not null, it is checked in step ST1601 if the alarm type of the current record is the same as the alarm type already stored in the trace data setting condition of the trace data setting condition holding unit 111j. If they are the same, only the trace data type is stored. If they are not the same, the process moves to the trace data setting condition of the next trace data setting condition holding unit 111j + 1, and the alarm type and the trace data type are stored. In step ST1605, steps ST1600 to ST1604 are executed in a loop for the number of records in the alarm trace data table 110 acquired in step ST1005.

  When an alarm is generated, data trace optimum for the control application can be collected by executing data trace based on the contents of the trace data setting condition stored in the trace data setting condition holding means 111j by the trace data setting means 105. Since the trace function itself is a known function, details are not described here.

  As described above, the motion system and its trace data setting method according to the present embodiment specify the alarm trace table type corresponding to the control application program selected from the device configuration information and the model information, and the alarm trace table type. The alarm type and the trace data type acquired from the server 4 based on the above and stored in the alarm trace table 110 are set as the trigger alarm type and the data type to be traced according to the control target device 2i, and the trace data type is set for each alarm type. Therefore, only the trace data related to the generated alarm can be collected.

  The present invention can be applied to a data trace setting for monitoring a failure of a controlled object controlled by a motion controller in general industrial equipment.
