Using a template program with Autolearn
In step 6 of the procedure outlined above, the tester provides a prompt allowing for the selection of
another program to be used as a template for the autolearn process. There are several potential reasons
for using a template:
•
Use of a specific Workflow
•
Defining variables, wire colors, or other program properties
•
Fixture block/pin naming
•
Defining additional phases for standard operations for all wire harnesses
In order to use another NX program as a template, the template program must already reside on the NX
tester. In step 6 above, select “YES” at the “Select a Template?” prompt, then using the arrow keys,
scroll through the directory until the desired program is found. When the Green button is pressed, the
NX Tester will immediately start the Autolearn process, using the selected program as a template.
The following provides additonal details about using a template program for Autolearn.
Use of a specific Workflow
The standard Autolearn process uses the default Workflow. This may not be suitable in all
situations. For instance, if label printing is required, if a report is to be generated, if the default
thresholds are not suitable, or if any function is required that is not provided in the default
workflow, use of a template with the desired workflow is needed. To use this capability, create a
NX Editor program that contains the desired Workflow. It is not necessary to define anything else
in this program – a “Workflow only” program is sufficient. Transfer this program to the NX
Tester, and select this program as the template. The Autolearn process will generate a test program
whose Workflow is identical to the one defined in the template program.
Defining variables, wire colors, or other program properties
Wire colors, part numbers, and other variables are defined in the Program Properties section of the
NX Editor. A standard Autolearn program will use the default wire colors, and will have all other
variables blank. If it is desirable for the Autolearned program to have a different set of wire colors
than the default, or to have defined variables or part numbers, then create a NX Editor program that
contains the desired Program Properties values. Transfer this program to the NX Tester, and select
this program as the template. The Autolearn process will generate a test program whose Program
Properties values are identical to the one defined in the template program. Note: if multiple part
numbers are defined in the template, the Autolearned program will have all check boxes checked
for all part numbers in the Main Phase. Note that to take advantage of wire colors or multiple part
numbers in an Autolearned program, it will be necessary to post-edit the program with the NX
Editor to make the necessary wire color assignments and part number assignments in the
Connections view.
Fixture block/pin naming
Under certain circumstances, it may be desireable for the Autolearned harness to conform to a
specific set of pre-defined fixture block/pin names. The most likely case for this is when several
different wire harnesses are tested using the same fixture board. In this case, create a NX Editor
program with all the desired fixture block/pin names and test point assignments pre-defined in the
Fixtures View. Transfer this program to the NX Tester, and select this program as the template.
The Autolearn process will generate a program whose Fixtures view includes the fixture block/pin
names and corresponding test point assignments as defined in the template program. Note that the
Autolearned program will have an entry in the Fixtures view corresponding to every test point that
resides on the tester. Test points that are not defined in the template program will be assigned a
