Use the General page to define the general settings for a data logger. The following is an example of the General page.

The table below describes each property in the General page.

		At Each	Fixed Moments
Property		Description
Name		The data logger's name. The maximum length of the name is 48 characters.
ID		The data logger's ID number. Select a number between 0 and 15. The number is unique among all data loggers of the panel application.
Read Address		Specifies the variable representing the data block to be sampled. Click to enter an address for this field. Click to select a tag for this field. The size of the data block is specified in the Sample Size field.
Sample Size		The size of the data to be sampled. The unit is word.
Number of Samples		Specifies the maximum number of samples that the logging buffer of the data logger can hold.
Sampling Method	Timed	The data logger samples data periodically at a rate specified in the Interval field. You can specify an interval between 1 and 65535 seconds for the Interval field. For example, if you want the data logger to sample data every 5 seconds, specify 5 for the Interval field.
	Triggered	The data logger samples data once whenever the trigger bit specified in the Trigger Bit field changes from Off to On.
	Clocked	The data logger samples data at fixed moments specified in the At Each field. There are six sets of fixed moments available for the At Each field.
		1x	Every minute at 0 second
		5x	The following moments of every hour: 00:00, 05:00, 10:00, 15:00, 20:00, 25:00, 30:00, 35:00, 40:00, 45:00, 50:00, 55:00
		10x	The following moments of every hour: 00:00, 10:00, 20:00, 30:00, 40:00, 50:00
		15x	The following moments of every hour: 00:00, 15:00, 30:00, 45:00
		30x	The following moments of every hour: 00:00, 30:00
		60x	Every hour on the hour
	Timed (sub-second)	The data logger samples data periodically at a rate specified in the Interval field. You can select an interval between 0.1 and 0.9 seconds for the Interval field. For example, if you want the data logger to sample data every 0.5 seconds, select 0.5 for the Interval field. The sub-second sampling requires high data acquisition performance. As there are many factors that can affect performance, it is not guaranteed that the specified sampling rate can be attained.
	Passive	The data logger does not sample data, but receives data from primary data logger by using SAVE2LB macro command or a LDF/CSV/TXT file. For details about the passive method, please see Section 13.1.4. Using File to Save Logged Data.
Data Logging Macro	Data Logging Macro	Check the option to log processed data instead of original data. For details about the data logging macro, please see Section 13.1.5. Using Data Logging Macro to log processed data.
	Sampled Data Buffer	Specifies the variable representing the data buffer for data logging macro to save the sampled data. The buffer size is the sample size. Click to enter an address for this field. Click to select a tag for this field.
	Size of the data to be logged by the macro	Specifies the size of the data to be logged by the macro.
Logging Buffer Size		The size of the logging buffer. The unit is word. The formula to calculate the size is:
		Sampling Method	Record Size	Logging Buffer Size	Remark
		Timed (sub-second)	Odd Number	Number of Samples * (Record Size + 6 + 1)	The number 6 is the size of the time stamp. The number 1 is to make each record double-word aligned.
		Timed (sub-second)	Even Number	Number of Samples * (Record Size + 6)
		All Others	Odd Number	Number of Samples * (Record Size + 5)	The number 5 is the size of the time stamp. The number 1 is to make each record double-word aligned.
		All Others	Even Number	Number of Samples * (Record Size + 5 + 1)
		Note: If the Data Logging Macro is used, the record size will be the size of the data to be logged by the macro. Otherwise the record size is the sample size.
Storage	Battery Backed RAM	Check this option so the logging buffer of the data logger will be located in the battery backed RAM. The logged data will not be lost after power down if the battery backed RAM is used as the logging buffer.
	RAM (volatile)	Check this option so the logging buffer will be located in an ordinary RAM, and the data logger will clear the logging buffer whenever the target panel is powered up.
	Flash Memory	The X series HMI unit allows the data loggers to save the collected data in the flash memory. This feature enlarges the non-volatile storage for real-time data collection from 1 MB to 100 MB.
	File	Check this option so the logging buffer will be located in the specified file.
Sample Full Processing	Stop Sampling	Check the option if you want the data logger to stop sampling data when the logging buffer is full.
	Notify	Check the option if you want the data logger to set the bit specified in the Bit field to On when the number of collected samples exceeds the limit specified in the Full Limit field.
	Bit	Available when the Notify field is checked. Specifies the bit for the sample full notification. Click to enter an address for this field. Click to select a tag for this field.
	Full Limit	Available when the Notify field is checked. Select a percentage as the full limit. When the ratio of collected samples to maximum samples specified in the Number of Samples field exceeds the percentage, the data logger sets the bit specified in the Bit field to On.
External Control	Clear Buffer	Check this option so the data logger can be controlled to clear its logging buffer with the trigger bit specified in the Trigger Bit field.
	Trigger Bit	Available when the Clear Buffer option is checked. Select a trigger bit that will control the data logger to clear its logging buffer. The data logger clears its logging buffer when the trigger bit changes from Off to On.
	Enable Sampling	Check this option so the data logger can be enabled and disabled by the enabling bit specified in the Enabling Bit field.
	Enabling Bit	Available when the Enable Sampling option is checked. Select an enabling bit that will enable and disable the data logger. The data logger is enabled when the enabling bit is On.
Latest Recorded Data	Word Address	You can use the addresses shown here to refer to the latest sampled data of the data logger for configuring screen objects and writing macros.
