How can TKE Technology help troubleshoot and test a CAN bus system?
TKE Technology helps identify and resolve CAN and CANopen communication problems in industrial and mobile machinery. Our testing and troubleshooting services cover network traffic analysis, error frames, bus load, message timing, physical layer signals, wiring, termination, grounding, EMC disturbances, and device interoperability.
We can support both new and existing control systems by locating the root cause of communication faults, validating CAN hardware and system implementations, reviewing protocol configurations, and improving network reliability and performance. Troubleshooting can be carried out remotely or on-site, depending on the system and the issue.

CAN network analysis involves examining network traffic, message timing, error frames, bus load, and physical layer signals to identify communication issues and optimize network performance.
Common causes include incorrect termination, wiring faults, signal reflections, EMC interference, grounding issues, overloaded networks, configuration errors, and device implementation issues. Identifying the root cause typically requires network analysis and diagnostics.
We analyze network traffic, inspect physical layer conditions, review configurations, and validate protocol implementations to identify root causes.
Testing is recommended during system development, before commissioning, after major modifications, when communication issues occur, or when preparing for certification and validation activities.
CANopen conformance testing verifies that a device correctly implements the CANopen standard and can communicate reliably with other CANopen devices.
Yes. We perform implementation reviews, interoperability testing, and CANopen conformance testing. Validation helps ensure interoperability, reduces integration risks, improves reliability, and identifies implementation issues before deployment
Yes. Depending on the project, troubleshooting and testing can be performed remotely or on-site to investigate communication issues directly in the operational environment.
The timeline depends on the complexity of the system and the nature of the issue. Simple faults can often be identified quickly, while more complex problems may require detailed measurements and analysis.
