3. DARTS Overview DARTS is short for Data Analysis ReposiTory System
DARTS is the PAM replacement ++
More types of data will included in the future such as Emissions, etc.
Like PAM
Steady state headers
Datapoints
MUA data
Better than PAM
RAPID dlogger
Indicom ifiles
ECFG / XCAL (on Z drive) ECM parameters / units* Enhanced USER keywords*
Central
Node
Test Cell
DARTS *
Coming late 2018 – requires CyFlex 6.3

4. DARTS Data Movement – Overview
Configuring Cyflex Central Node for DARTS
During transition period,
Data will be sent to both
DARTS and PAM.

5. DARTS Path DARTS requires the following keywords:
Program has to be valid DARTS program (or McParts engine family), refer to:
Valid Programs for DARTS
DARTS Path
engine_specs
pam_specs
dlogger_specs
afix
avl_link
Engine Program Code
program
C_PROGRAM
@PROGRAM
“$program”
Test Name
test_type
C_TEST_TYPE
@TEST_TYPE
“$test_type”
Test Mode Name
mode
C_MODE
@MODE
“$mode”
Test Data Group Name
group
C_GROUP
@GROUP
Test ID
@TEST_ID
“$tpid” or “$Test_ID”
tpid or Test_ID
Group by Date*
group_by_date
C_GROUP_BY_DATE
* ‘Group by date’ is a flag to DARTS to turn off auto date grouping

6. DARTS Path (Cont.)
The DARTS Path can be thought of as a folder to contain data
For Steady-State data, a header with the DARTS path needs to be sent before sending datapoints (i.e. create the DARTS folder to contain the data)
Run eng_specs
If Datapoint files are sent with no header:
Datapoint files will be stored in hold folder
Errors will be displayed on the DARTS Job Status page
Datapoint files need to be resent after Header was sent to DARTS

7. What’s not allowed in DARTS
Duplicate keywords in a datapoint is not allowed
Same keyword with different valid suffix or extension ‘.’ are not considered duplicate.
PAM groups are not supported in DARTS
DARTS paths are the replacement
Probably will want to set group_by_date to ‘false’ to prevent auto group dating
Make it sub-bullet point for suffix
Only preferred keyword will be in DARTS, PAM aliases will not be in DARTS

8. Sending Steady-State Data
DARTS path need to be updated in the engine_specs file
Edit /specs/engine_specs.nnn file (nnn refers to the test cell number)
Add program, test_type, mode, group parameters
Optionally, add group_by_date parameter.
If set to FALSE it will inhibit DARTS from grouping by date
Run eng_specs command
This creates ‘folder’ in the DARTS landing zone
Check on DARTS Job Status page to verify if header file is successfully loaded

9. Sending Steady-State Data
Example of engine_specs.nnn:
DARTS Paths information
DARTS Paths information
Cummins Internal Use Only

10. Sending Steady-State Data
Example of engine_specs.nnn:
“group_by_date” if set to
FALSE – This will inhibit DARTS from
grouping by date.

11. Sending Steady-State Data
Update pam_spec file, add DARTS path and group_by_date labels
Labels should be the same with
engine_specs.
Cummins Internal Use Only

12. Sending Steady-State Data
Run take_dum_fr after pam_specs is updated
Check on DARTS Job Status page, to verify if datapoint file is successfully loaded
Notes:
** The Program label must be set to a valid DARTS program name (usually the same as the McParts engine family name)
** The values of test_type, mode, and group labels must be set as per best practices defined by the test team leader

13. Sending Dlogger Data Dlogger is similar to floger, except
dlogger data will automatically be sent to DARTS
Requires DARTS path information
Requires DARTS (PAM) keywords as channels
Cummins Internal Use Only

14. Sending Dlogger Data Dlogger Setup: Create dlogger spec file
Example dlogger spec file content:
Dlogger ID
DARTS Path
Cummins Internal Use Only

15. Sending Dlogger Data Example dlogger spec file content:
“group_by_date” if set to
FALSE – This will inhibit
DARTS from grouping by date.
Cummins Internal Use Only

16. Sending Dlogger Data Dlogger Setup:
Dlogger ID is unique to the machine
If Dlogger is stopped and then restart without changing Dlogger ID, the data will be appended to the previous data log
Run the dlogger from the command line:
dlogger specFileName
Stop the dlogger, if needed
Check on DARTS Job Status page, to verify if dlogger file is successfully loaded
* For more detail on dlogger, visit Logging Data Using dlogger on ewiki
