This extension module for the canAnalyser enables the interpretation of received CAN messages in accordance with the ODVA DeviceNet standard. Received messages are analyzed according to the type of message and displayed as plain text. By means of powerful filters, the data to be displayed can be specifically selected. Therefore, the module is suitable for both developers of DeviceNet devices and for troubleshooting and analysis of DeviceNet networks and systems.

Functions

The DeviceNet module interprets all received CAN messages according to their DeviceNet significance and displays the received parameters according to Message Group, MAC ID and Message ID. The incoming information is 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 DeviceNet 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. Furthermore the fragmentation protocol is analyzed and monitored. The interpretation of Explicit Messages is based on the connection table which contains the used message format. The connection table is filled automatically by detection of the connection set-up and can be configured manually.
• I/O Messages: Support of both Predefined Master/Slave Connection Set (Poll, Bit-Strobe, COS/Cyclic, Multicast Poll) and dynamic messages from groups 1 and 3. Fragmented I/O Messages can be configured by the user; for these messages, the fragmentation protocol is analyzed and monitored.
• Unconnected: Unconnected Message Manager Port (UCMM) and Unconnected Port of the Predefined Master Slave Connection Set are supported.

In addition, filtering of the received messages according to both MAC-ID and message type can be set and saved during operation.

For further processing of the interpreted data in other applications, the content of the analysis window can be exported to a text file (CSV format). Because of its flexible filter configuration and the comprehensive interpretation basis, the DeviceNet module is suitable for all DeviceNet systems.
