Statistical Counting

## Statistical Counting
Counts the detection yield and saves required data to the hard disk.

## Module Principle
This module calculates the yield based on the total input result. If additional input ports are added, the values from those input ports will be saved to the hard disk.

## Usage Scenarios
This module is used in scenarios where detection yield needs to be calculated or detection data needs to be saved to the hard disk.

## Parameter Configuration Description
### Enable Statistical Counting
Enables the statistical counting function when checked.
### Save Total Result
Saves the total result at the end of each data row when checked.
### Enable Statistics Clear Signal
When checked, a statistics clear signal can be introduced externally. When this signal is true, the statistical data will be cleared.
### Create Date Directory Under Save Path
When checked, folders named by year, month, and day will be created under the specified save directory to store data.
### External Input File Name
When checked, a string can be introduced externally as the name of the saved file. The input name cannot contain characters such as \ / : * ? " < > |.
### Save Cache Size
A save operation is performed when the number of detections reaches this value. This parameter is used to reduce the frequency of hard disk reads/writes and improve detection efficiency.
### File Retention Time
The storage time for saved files on the hard disk. When this time is exceeded, the software will automatically delete the files during the next save operation.
### Enable New File Generation Signal, Disable to Generate One File Per Day
When checked, a new file generation signal can be introduced externally. When this signal is true during a file save, a new file will be generated.
### Clear Statistical Count
Manually clears the statistical count data.
### File Save Path
The hard disk folder path for saving data.

## Output Description
### Run Result
Indicates whether the module run was successful.
### Total Pass Count
The total number of times the total input result was true.
### Pass Yield
The percentage of true total input results out of the total count.
### Total Fail Count
The total number of times the total input result was false.
### Fail Rate
The percentage of false total input results out of the total count.
### Total Product Count
The total number of total input results.

## Notes
1. When introducing the file name externally, it cannot contain characters such as \ / : * ? " < > | or escape characters.
2. The number of detections must be greater than or equal to the save cache size for the software to save data to the hard disk; otherwise, the data will be cached in memory and not written to the hard disk.
3. As the saved file format is CSV, you can directly open it with Excel software to view the saved data.
