1 Introduction

Some supplier want to use VTP as their communication software, but they only get the CANdbc file from the OEM. This document shows how to get configuration files in this case.

2 Object

The purpose of this document is to describe step by step how to import CANdbc file into VNA, and then generated configuration files. It is for supplier use.

3 Revision Histroy

4 Import CANdbc

The following steps describe how to import objects in a CANdbc file into VNA.

4.1 Step1: open VNA Import-Export Utility

It will ask you to choose your Destination Database , you need to connect to a database (can be an empty or exist database),or you can choose to connect to Destination Database later by click Database/Connect to Destination

4.2 Step2: default timing information for signal and frame

Please set you default timing information by click File\\Setting\\Timing Settings. Since you want to import the frame period from the CANdbc file or set the period by manually, you need to keep these information empty.

4.3 Step3: Attribute Mapping

Please set your attribute mapping information by click File\\Setting\\Timing Settings. This is because there are different attribute name for same objects between VNA database and CANdbc. You can either use our default mapping or edit by yourself, do not forget to save it.
