Description: |
The CSV Data Feed component allows the row by row reading of an existing data spreadsheet. By specifying the csv file, the component automatically exposes an input for each of the columns of data, with the name of the input set at the header of the column. When the simulator runs, each cycle will cause the row reader pointer to advance by one, effectively feeding each row of data into the system for consumption by other components. Various information about the size and state of file and read operation are also exposed, allowing dynamic decisions about further reading to be made via custom system logic. One of the most useful outputs is the enabled output, which effectively flags when the end of the file has been reached. Components can use this value to determine when computation should end on exposed values. Also, in the Data Import properties dialog box, the option to repeat at end of file is presented. This allows the read operation to repeat at the first row of data when the end of file is reached. This is useful when training other components or tuning system to ideal positions. |
