Using NI-VCOM Toolkit to Configure Rolling Counter for CAN Application

Updated Feb 7, 2025

Environment

Software

  • Vehicle Communication Toolkit

Driver

  • NI-XNET

The Rolling Counter means adding 1 to the Rolling Counter bits every time a frame is sent. Assuming that the Rolling Counter is 4bit, then the Rolling Counter will increase cyclically between 0-15. When the ECU detects that the Rolling Counter has a jump, such as jumping directly from 1 to 3, then the ECU knows that the frame with the Rolling Counter of 2 has not been received, and the ECU will generate a DTC (Diagnostic Trouble Code) signal, and then the ECU will Enter safe mode. NI-VCOM toolkit provides a tool to configure the Rolling counter for CAN frames. This article will introduce how to configure a Rolling Counter with the NI-VCOM toolkit.

  1. Open the RBSConfig Software

You have 2 different ways to open the software.
a. Open LabVIEW, then select Tools>>Vehicle Communication Toolkit>>Legacy>>DBC and LDF RBSConfig...
