CANopen Logxaminer


Embedded Systems Academy's Logxaminer helps with complex post-recording analysis of long-term logs containing CANopen traffic data covering multiple hours or sometimes even days. Instead of loading the log file into a spread sheet program and do manual searches, color highlighting and sometimes run custom scripts or macros to help locating issues, this tool creates statistics and event lists on a configurable level of detail. This drastically shortens the time to get "real results" out of a CANopen log recording made. Statistics are not only produced globally, there are dedicated statistic views for each node present on the network during the recording.

Per node statistics include:

  • Minimum/maximum heartbeat time
  • Minimum/maximum SDO response time
  • Number of bootups
  • Number of emergencies transmitted
  • PDO message rate

The Logxaminer not only produces statistics, it also generates an event listing with all important system events. The event listing filters information from the log including:

  • Node ID assignment (by LSS)
  • Bootups (expected/unexpected)
  • Emergencies
  • SDO Aborts
  • Unexpected messages (out of order sequences)

If a network is not running stable, then the system event listing highlights important clues as to what goes wrong where.
