The CANobserver is a stationary tool, that is used for physical and logical long-term monitoring of CAN bus plants (CAN, CANopen, DeviceNet).

Once the plant stands still, it is too late in most cases. In order to initiate steps against this, both the components of the plant and the supply network have to be maintained continuously. The operation parameters of the bus system degrades due to wear. Gemac's CANobserver diagnoses such changes while day-to-day functioning continues and informs the plant operator.
The CANobserver is a diagnose tool that's used for physical and logical long-term monitoring of CAN bus plants. It has been planned as a stationary supplement of the CAN-bus tester 2. The CANobserver is implemented into the network permanently and monitors the data transfer continuously. This is the optimal means of safeguarding a future-oriented maintenance. VDI/VDE has recognized this necessity as well. The new guideline VDI/VDE 2184, published in 2007, explains how plant operators can guarantee a reliable functioning and maintenance of their field bus systems.
