The CANobserver is a diagnosis tool for the physical and logical long-term monitoring of CAN bus systems and is designed as a stationary supplement to the CAN bus tester 2.

Once the system is at a standstill, the damage is usually great.

In order to be able to initiate countermeasures in good time, both the plant components and the pipeline system as a whole should be continuously maintained. Due to wear, the operating parameters of the bus system deteriorate. Our CANobserver diagnoses such changes during operation and reports them to the plant operator.
