OEM Shop Floor Program
OEM Programs vary in complexity
Simple
- Some OEM Shop Floor Programs simply invoke the VCP
and pass it a pre-generated parameter file.
Complex
- Other OEM Shop Floor Programs are tied in to order entry
system through data bases and generate unique parameter
files based on a customers order.
VCP Invocation
from Shortcut
Here is an example
shortcut properties
box that will use the
PAR file:
C:\ParFiles\DE02.par
VCP Configuration
• Cummins VCP is configured using a control panel applet.
• This allows users to customize how the Cummins VCP works in their environment.
Cummins VCP
Data Integrity Cummins VCP ensures all the data in the parameter file
passes following requirements:
�Data Format- Ensures the format of the parameter record is valid
� Range Testing- Ensures the data is within a valid range- Ex: Max Road Speed is between 30 - 120 MPH
� Security- Ensures that correct Master Passwords/ OEM Passwords are provided
�Configuration- Ensures parameters do not cause / indicate conflicting operation- Ex: Cruise auto-resume enabled but cruise control was not enabled
�Feature Availability- Ensures the ECM supports the parameter before it is enabled
