Description

The present application relates to a system for restoring test data in a control device.

The input / output signal data of the control program set in the control device test is lost when the power of the control device is turned off. Therefore, when the power of the control device is turned on, the input / output signal data of the control program is set again one by one, and it takes time to restore the test data, resulting in poor work efficiency. In addition, the quality of test data cannot be ensured due to input errors. In order to improve this, a system that stores and restores the input / output signal data of the control program of the control device is required.

Conventional controller test data recovery systems include: That is, there is a device that executes a control program based on the input signal stored in the simulation data storage unit, generates an output signal as the execution result of the control program, and stores it in the simulation data storage unit.
Further, there is a trace recording device that stores the operation information used in the software test and the display information of the software which is the test result, and this information is used in the retest.

Prior art is related to a performance measuring device that continuously measures the performance of an information processing system under multiple different measurement conditions, and the generated test patterns and parameters are saved in the measurement condition file storage and reused. (See Patent Document 1).
Further, there is a control device in which the changed control program can be incorporated in place of the new control program, and the input signal and the output signal to be input to the control program are stored in the storage unit (see Patent Document 2). ..

In addition, multiple set tests are performed on the test target device, and when it is determined that the test target device is hung, the test is temporarily stopped, and after control by the hang-up post-processing unit, the remaining multiple tests are performed. (See Patent Document 3).
In addition, some have a trace recording device that stores the operation information used in the software test and the software display information that is the test result, and this information is used in the retest and also has an interrupt function ( See Patent Document 4).
