Click Tools > Data Logger from the main toolbar to open the [Data Logger] window. From this window, users can configure new data loggers, edit existing data loggers, and attach tags to data loggers. Users can create a new data logger by pressing the 
icon or by right-clicking and selecting [New Data Logger].
(1) Logger Settings
Once a new data logger has been created, the user is presented with the above [Logger Settings] tab. The features in this tab are explained in further detail in the following table.
Item | Description | |||
Logging Model Name | Enter the name of the Data Logging model. You may use alphanumeric characters, Korean alphabets, and special characters as the model name. You cannot use a duplicated model name. | |||
Max Logs | The maximum number of rows for the data logger. If the data logger hits the set maximum value in operation, the data logger continues to operate by discarding the oldest logged value for a new value. | |||
Time Stamp Format | Allows the user to customize the formatting of timestamps for the data logger’s data points. | |||
Start Options | Start Up | Enables the data logger on device start up. | ||
Manual | Enables the data logger on execution of a 'datalog.start(“Insert Logging Model Name”)' command. | |||
Condition | Enables the data logger when the [Trigger Tag] or address value meets the conditions specified by the [Comparison] and [Value] fields. When this option is used, the comparison condition is structured as follows: [Trigger Tag] [Comparison] [Value]. Example: For a Trigger Tag ‘Celsius’, a greater than comparator, and a value of 5, the comparison would be structured as follows: ‘Celsius’ > 5 | |||
Trigger Tag | Tag referenced by the [Comparison] operator. | |||
Comparison | Allows the user to select from six possible comparators: equal [=], does not equal [!=], greater than [>], greater than or equal to [>=], less than [<], and less than or equal to [<=]. | |||
Value | A numerical value or tag to be compared to the [Trigger Tag]. | |||
Logging Options | Allows the user to modify when a new row is added to the data logger. Note that the data logger must be started before a new row can be added. | |||
Periodic | Adds a row to the data logger at a set interval. Users can adjust this interval using the [Hours], [Minutes], [Seconds], and [Milliseconds] command. | |||
Tag Value Change | Adds a row to the data logger upon a change in the [Trigger Tag]'s value. | |||
Manual | Adds a row to the data logger upon execution of a ‘datalog.addrow(“Insert Logging Model Name”)' command. | |||
Condition | Adds a row to the data logger when the [Trigger Tag] or address value meets the conditions specified by the [Comparison] and [Value] fields. When this option is used, the comparison condition is structured as follows: [Trigger Tag] [Comparison] [Value]. Example: For a Trigger Tag ‘Celsius’, a greater than comparator, and a value of 5, the comparison would be structured as follows: ‘Celsius’ > 5 | |||
Trigger Tag | Tag referenced by the [Comparison] operator. | |||
Comparison | Allows the user to select from six possible comparators: equal [=], does not equal [!=], greater than [>], greater than or equal to [>=], less than [<], and less than or equal to [<=]. | |||
Value | A numerical value or tag to be compared to the [Trigger Tag]. | |||
2) Tag List
This tab of the [Data Logger] menu allows the user to assign multiple tags to a Data Logging Model. A new tag can be added by pressing the icon, or right-clicking and selecting [Add Tag(s)]. After selecting this option, users will be presented with a new pop-up window that functions similarly to the [Tag Browser]. Users can add selected tags by checking the box next to the tag, then pressing the [Select] button. Users can also remove tags from the Data Logging Model by pressing the icon or right-clicking and selecting [Delete].
