Descriptions
File Header
In the
File Header
 area, there are the following options:
  • Default -
    The control provides the column heading names. The default names are: "Alg1", "Alg2", ...,"Alg100", "Str1", "Str2", ...,"Str50"
  • Template -
    The application designer reads a CSV file that contains in its first row the desired column heading names for the log file. These entries in the external file are used as the column heading names.
  • Use Tag Names -
    The column headings for the float and string data match the tag names being logged.
Log Periodically
Once the control is enabled, it logs periodically based on the time interval entered in this box.
The time interval should be 1-9999s or 250-32767ms.
Log System Time and Date of each record
Select this option to automatically record a System Time and Date stamp with each log entry. When logging System Time and Date, there is an option to also log a System Timezone Indicator. The indicator will contain the offset from UTC (Coordinated Universal Time) and the system's local timezone.
Indicate Timezone
When logging System time, this option adds a timezone indicator to the record. The system's Regional Setting determines the timezone offset.
Log UTC Time and Date of each record
Select this option to automatically log a UTC Time and Date stamp with each record.
Overwrite oldest data when file reaches
This option begins to overwrite the oldest data in the log file when the file reaches a specified size creating a circular log file.
Log assigned connections only
This option optimizes the size of the log file by only logging configured connections.
If this option is not selected, each record will always contain entries for 100 float and 50 string values.
Enable tamper detection
If this check box is selected, the log file generated by the CSVDataLog ActiveX control contains tamper detection strings. You can use the CSV Data Log Tamper Detection Utility to detect the integrity of the log file.
If this check box is clear, the log file generated by the CSVDataLog ActiveX control is in the same format with the log file generated by the DataStorePlus ActiveX control.
CSV File Logging Order
This option allows the designer to configure the order, in which data is written to the log file.
