Data Monitor/Logger on Cummins INSITE Software (CUMMINS Engines)

Data Monitor/Logger

Figure 1.1 - Data Monitor/Logger (All Parameters)

Use the Data Monitor/Logger to view live engine data, or to log monitor data to a file for later analysis. The technician can select specific parameters for monitoring or select predefined or customized parameter groups. The sampling rate that the monitored parameters are updated can also be adjusted.

Once the parameters have been selected, they can be monitored only (no recording) or monitored and logged (recorded as a flow of data). Additionally, Snapshots can be taken at any time. A Snapshot is a file showing the values of the selected parameters at a specific moment.

The Data Monitor/Logger can also be used to monitor or log ECM data during testing.
  • Select Data Monitor/Logger from the Viewbar (left-side menu).
  • Select View > Current > Data Monitor/Logger from the menu bar. 

The Data Monitor/Logger Window
The Data Monitor/Logger window has three areas: Parameter Groups, Parameters and Selected Parameters List.
Figure 1.2 - Data Monitor/Logger
A. Parameters Groups
Parameter Groups are displayed in the upper left portion of the Data Monitor/Logger window. INSITE™ has predefined monitor groups (e.g. Engine Braking, Switches, Sensors, etc.) Custom groups may also be defined as needed.

B. Parameters
Parameters are displayed in the lower left portion of the Data Monitor/Logger window. They are grouped by ECM. Individual parameters may be selected from this area to be monitored. Parameters that have been added to the Selected Parameters list will have a monitor icon in front of them. Parameters that are part of a Predefined or Custom Monitor Group are displayed in bold font when that monitor group is selected.
C. Selected Parameters List
Selected Parameters are displayed on the right-hand portion of the Data Monitor/Logger window. The selected parameters, the current values of those parameters (once logging or monitoring is started), the units of measure and the Upper and Lower Limits for the parameters are displayed in this area when available.

Once the parameters have been selected, the Parameter Groups and Parameters areas can be hidden by selecting the Hide button on the bar to the left of the Selected Parameters List. Select the Show button to display these areas again.


Logs and Snapshots
There are two ways to save monitoring data for later review. It can be saved as a Snapshot or as a Log. Snapshots contain a single occurrence of all selected parameters. A Log contains data from each of the selected parameters while the log was running.

1). Data Logs
A data log captures the values of the Selected Parameter List as they are updated in the Data Monitor/Logger window. When the data has been collected, it can be written to a file. Log files can become very large. The amount of data collected for each parameter is determined by the Sampling Rate and the duration of the log. (For Example: If the sampling rate is set to 10 second and the log is run for 5 minutes, there will 30 values recorded for each parameter).

Logging Data
A. Specify the Monitor/Logger setup.
Note: Parameters may be added or removed from the selected parameter list while logging is in progress.
B. Perform one of the three steps below to begin logging data:
→Right click anywhere in the Selected Parameter List and select Log Data from the menu.
→Select the Log Data icon from the toolbar.
→Select Tools > Data Monitor/Logger > Log Data from the menu bar.
Figure 1.4 - Log Data

C. The selected parameters will begin to update at the specified sampling rate and an animated scrolling icon will appear in the status bar.
→Start/Resume
If the data monitoring or logging process has not been started, select this option to begin monitoring the selected parameters. If data was being monitored or logged and then paused, selecting this option will resume the monitoring or logging process.
→Pause
Select this option to pause the monitoring or data logging.
→Stop
Select this option to stop the monitoring or logging data.

D. If the Stop command is active, the selected parameters will stop being updated. The scrolling icon in the status bar will disappear and the Save Logged Data window will appear.
Figure 1.5 - Save Logged Data

E. If desired, select file location, file name, and file format or accept default values.
Note: The default file name starts with the user name (if User Manager is enabled) or “DML-” (if User Manager is disabled) followed by the year, month, day, hour, minute and second that the snapshot was captured. (Example: DML-20200806-135109 was captured at 1:51:09 PM on August 6, 2020).
F. Select Save and Enter Log File Comments. The Log File can be viewed using any third party software that will accept the selected format.

G. Find the saved file on Local Disk (C:)\Intelect\INSITE\Logs (DML-20200806-135109).

2). Snapshots
A data snapshot is an instantaneous record of all selected parameters. A snapshot can be captured at any time while monitoring or logging is in progress or paused. A snapshot can only be captured while viewing the Data Monitor/Logger window.

Capturing a snapshot
A. Specify the Monitor/Logger setup.
B. Ensure that the monitoring or logging process is running. 
C. Perform one of the three steps below to capture a snapshot:
→Right click anywhere in the Selected Parameter List and select Snapshot from the menu. 
→Select the Snapshot icon from the toolbar.
→Select Tools> Data Monitor/Logger> Snapshot from the menu bar.
Figure 1.8 - Snapshots 

D. The Save Snapshot Data pop-up window will appear.
Figure 1.9 - Save Snapshot Data

E. If desired, select file location, file name, and file format or accept default values.
Note: The default file name starts with the user name (if User Manager is enabled) or “DML-” (if User Manager is disabled) followed by the year, month, day, hour, minute and second that the snapshot was captured. (Example: DML-20200809-215456 was captured at 9:54:56 PM on August 9, 2020).
F. Select Save and Enter Log File Comments. The Log File can be viewed using any third party software that will accept the selected format.
G. Find the saved file on Local Disk (C:)\Intelect\INSITE\Logs (DML-20200809-215456).

  2. A computer Best Monitor usually displays the visual output as it is given by the keyboard. Choosing the right type of monitor that will best suit your application needs in the sense looking at the power usage and its size is highly challenging. LCD monitors have become the popular choice of many people.
