CANobserver
The CANobserver is integrated permanently into the network, monitors the data transfer continuously and records it automatically.
Sporadic bus interferences, such as external EMC interference or a slowly deteriorating signal quality attributable to worn plug connections, can be detected in good time. To this end, the signal conditions of each CAN bus node are subjected to a physical and logical evaluation and any deviations from a predefined threshold value are recorded. In this context, the physical layer diagnosis of the CANobserver offers decisive advantages: It reveals error sources in the physical set-up of CAN, CANopen, DeviceNet and SAE J1939 systems at an early stage. Thus, CANobserver is already able to inform the system operator before any communication error occurs.
