13.2.2 Creating a Data Logging Group

Use the Data Logging node in the Navigator window to display the Data Logging spreadsheet. In the Data Logging spreadsheet, you can create up to 80 data logging groups for each target and manage the logging group settings. In the spreadsheet, all the columns are read only except for the Logging Group column. You can use the drop-down combo box to select a logging group from a list of all the logging groups in the target.

  1. Right-click the Data Logging node, and select New Data Logging Group.

You have created a new data logging group. The Data Logging spreadsheet displays so you can associate variables with the data logging group and manage the logging group settings.

  1. In the Data Logging spreadsheet, click Logging Group Settings to open the Logging Group Settings.
  2. Define the properties in the Logging Group Settings dialog box.

 

 

The following table describes each property in the Logging Group Settings dialog box. Make changes to the settings as required.

Property

Description

Sampling Tab

Name

The data logging group's name. Whenever a data logging group is created, a default name is generated. When renaming a data logging group, its name must be unique within the target, must contain no more than 32 valid characters, and must follow the naming conventions.

For more information, see Appendix 9, Naming Conventions.

Type

Specify the data sampling method by selecting either the Periodic or Trigger.

  • Periodic gives you a snapshot of the data at regular time intervals. When selected, the Start of Day (HH:MM), Units, and Sampling Frequency Slider properties are displayed.
  • Trigger gives you a snapshot of the data when a trigger is activated. When selected, the Trigger Variable, Trigger Condition, and Status Variable properties are displayed.

For more information on data sampling, see Section 13.1.1.2, Specifying When to Collect Data.

Click to open the Logging Group Settings dialog box.

Deadband

The deadband feature allows records to log only when the variable value falls below or exceeds the deviation value from the variable value of the last record.

Deadband reduces log file size and the amount of log file records.

Deviation (Fixed)

Enter a numeric value that specifies the deviation value. The valid range is 0 and 1.1754e-038 to 3.4028e+038.

For example, if the previous variable value was 320 and you set the deviation value to 8, no new record logs if the variable value of the current sample falls within 312 and 328. However, if the value is less than 312 or greater than 328, a new record logs.

If you enter 0, the deadband feature will be disabled.

Units

Specify the unit (hours, minutes, or seconds) to use for the sample rate. The selection you make determines the sampling frequency range that will be displayed in the next property.

Sampling Frequency Slider

Specify how many hours, minutes, or seconds (depends on your selection in the Units property) are to elapse before taking a sample.

 

When Hours is selected, data collection can take place every 1, 2, 3, 4, 6, 8, 12, 16, or 24 hours.

 

 

 

When Minutes is selected, data collection can take place every 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, or 30 minutes.

 

 

 

When Seconds is selected, data collection can take place every 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, or 30 seconds.

 

 

Trigger Condition

The Trigger Variable is evaluated using the condition selected here. When the condition is met, data collection takes place. Select When True, When False, and On Data Change.

  • When True. Whenever the Trigger Variable changes from 0 to any value, a snapshot of the data is taken.
  • When False. Whenever the Trigger Variable changes to 0 from any value, a snapshot of the data is taken.
  • On Data Change. Whenever the Trigger Variable changes in value, a snapshot of the data is taken.

Trigger Variable

Enter an integer or BOOL variable to control when data collection takes place. You can enter a string variable if the Trigger Condition is set to On Data Change. Use Trigger Condition to define how this variable triggers data collection.

Status Variable

Enter an integer or BOOL to inform you when data collection is taking place and when it is completed.

  • When data collection is completed, the status variable is set to 1 (True).
  • When the trigger variable is cleared, the status variable is reset to 0 (False).

After the status variable is reset to 0, you can set the trigger variable to activate data collection again.

Variable Storage Tab

Type

Select DRAM, SRAM, or SRAM and File to specify the storage option for your collected data.

  • DRAM. Preserves only the most recent data.
  • SRAM. Preserves a specified number of data records for a data logging group.
  • SRAM and File. Preserves data in the SRAM until its capacity is reached, and then the data in SRAM is written to file. The file format is DYYMMDDX.dat, where:
  • D is the prefix indicating that this is a data logging file.
  • YYMMDD is the date on which the file is created.
  • X is the file sequence counter from 0-Z (using the integers 0-9 and characters A-Z). The file sequence counter allows you to log 36 files. Files logged after that will overwrite file Z.

No. of Records in RAM

Specify how many data records are to be stored in DRAM or SRAM. For DRAM storage, you can specify from 10 to 1000 data records. For SRAM storage, you can specify from 10 to 300 data records.

File Limit

Specify whether you want to limit the size of the data logging files by Days or Size.

No. of Days

If you selected Days, specify the number of days' worth of data records that you want stored in the file. You can specify from 1 to 1825 days. This property is available when you select SRAM and File as your storage type.

Maximum Data Size

If you selected Size, specify the maximum size of the data (in kilobytes) for each variable to be stored in the file. You can store from 250 to 8192 KB. This property is available when you select SRAM and File as your storage type.

No. of Files to Keep

Specify the number of files to be kept for each variable. Enter a value from 1 to 999.

Group RAM Usage

This property is read only. It displays RAM usage of the variables in a data logging group.

Number of Days

This property is read only and is available when SRAM and File storage type is selected. This property is useful when File Limit is set to Size and the maximum data size is specified. This property then displays the estimated number of days it would take to reach the specified data file size.

Group File Size

This property is read only and is available when SRAM and File storage type is selected. It displays the estimated data logging file size (in KB) for the data logging group.

Units

For the Trigger Type, you would typically define the Units in the Variable Storage tab, as this property does not display in the Sampling tab for the Trigger Type.

For more information, see the above description in this table.

Sampling Frequency Slider

For the Trigger Type, you would typically define the sampling frequency in the Variable Storage tab, as this property does not display in the Sampling tab for the Trigger Type.

For more information, see the above description in this table.

Advanced Tab

Enable Interlock

Select Enable Interlock to set up a condition that must be true in order to start data collection. The condition can be a BOOL, integer variable, or boolean expression.

For more information, see Section 9.6, Using Interlock to Prevent Accidental Touch Input
