DeviceNet Module

-DeviceNet Interpreter for canAnalyser

Overview

This extension module for canAnalyser enables interpretation of the received CAN messages in accordance with the ODVA DeviceNet standard. The messages in accordance with the ODVA DeviceNet standard. The messages are displayed in color in plaintext together with their parameters. By means of powerful filters the data to be displayed can be specifically selected. The nodule is therefore suitable for troubleshooting and analysis of DeviceNet networks and systems.

Description of Functions

The DeviceNet module interprets all received CAN messages according to their DeviceNet significance and displays the transmitted parameters according to message group, MAC-ID and message-ID. The incoming information are divided into unconnected message, explicit message, I/O message, duplicate MAC-ID check message, device heartbeat message, device shutdown message, offline connection set as well as reserved and invalid CAN messages and their content decoded depending on type:

• Explicit messages: all specified common services and class names are displayed. The error responses are also represented.
• I/O messages: support of both predefined master/slave connection set (poll, bit-strobe, COS/cyclic, multicast poll) and dynamic messages from groups 1, 2 and 3.
• Unconnected: UCMM and unconnected port of the predefined master slave connection set are supported.

The basis for the interpretation of the received data is the configuration set. It defines the message format (8/8, 8/16, 16/8 or 16/16) for each node and the basic interpretation texts to be displayed and can be edited. In addition, filtering of the receive objects can be set and saved during operation according to both MAC-ID and message type. For further processing of the interpreted data in other applications, the content of the analysis window can be exported to a text file. Due to its flexible filter configuration and the comprehensive interpretation basis, the DeviceNet module is suitable for all DeviceNet systems.
