Description Technical Specs Downloads
The CANobserver® from GEMAC is a diagnostic device which is used for physical and logical long-term monitoring of CAN bus systems and has been designed as a stationary supplement to the CAN-Bus Tester 2. The CANobserver® is permanently implemented into the network, continuously monitors the data transfer and records it automatically for a period of up to ten years. On the basis of the physical properties of the CAN-Bus it recognizes system errors right in time and reports them immediately to the plant operator.

A slowly deteriorating signal quality can be detected in good time to avoid expensive system standstills. The CANobserver® is a unique device which ensures status-oriented maintenance. VDI/VDE has recognized this necessity as well. The new guideline 2184, published in 2007, explains how plant operators can guarantee reliable functioning and maintenance of their field bus systems.
