As an addition to the canAnalyser, the CANopen Module allows for the interpretation of CAN messages according to the CANopen standards. Here, the message types defined by CANopen together with their parameters, are displayed in color in plaintext. The module is suitable for the analysis of CANopen nodes and networks.

Description of functions

The CANopen Module interprets all received CAN messages according to the CANopen specifications DS-301, DS-302 (incl. Flying Master) and DS-305 (LSS). The messages are recognized as SDOs, PDOs (also multiplexed), NMT, Emergency, Sync and Timestamp objects and interpreted accordingly. Here, it is possible to filter the messages received according to both their node number and their message type. An SDO transfer is displayed with index and subindex and the symbolic name of the addressed object dictionary entry. Any abort code which may occur is correctly displayed with the SDO data transferred up to that point. The display is color coded according to the message type. In addition, the SDO display can be switched between the display of the individual subsequences and an overall display of the byte stream transferred. For each message type, the original raw CAN message can be displayed in order to detect additional or also incorrect protocol data.

The basis for the interpretation of the received data is the so-called configuration set. This either allocates an EDS/DCF file to the 127 possible network subscribers or defines its device profile. The configuration set can be loaded, edited and saved. In addition, it is possible to add, delete and modify the CAN objects used by each node and their CAN identifiers. The profiles used for interpretation are integrated via external ASCII files, allowing the CANopen Module to be easily extended by new profiles. Due to its flexible structure, the CANopen Module can be used universally in all CANopen systems.
