If the system stands still, the loss is usually high.
To perform some corrective action at the right time, system components and the whole guidance system should be maintained continual. Because of wear there are worsening of running parameters of the bus system. These changes are diagnosed from our CANobserver within the running system and are notified to the facility operator.
The CANobserver works within the networks CAN, CANopen, DeviceNet und SAE J1939.
Installation and Configuration
The CANobserver is designed to be permanent mounted into the bus. The top-hat rail makes it easy to install. It can use the bus power supply (9…36 V), additionally you need a Ethernet connection to connect.
Configuration is done in the web browser completely. Check if the alarm threshold fit to your system and put in the data for email sending.
On which problems you want to be warned, you define with your web browser. The following screenshot shows an example.
With the potential free switch you can switch a signaling lamp on top of your control cabinet for instance.
Additionally you can be warned via E-Mail and SMNP. Therefore an online connection to the ethernet network is needed.
The CANobserver is capable to measure and to show signal conditions of the CAN bus. It is possible to draw conclusions to perhaps existing problems about the nodes or the bus wiring by measurements of signal quality.
Active-Error /Passive-Error Frames
General Quality Level (0 … 100 %)
Disturbance-free Voltage Range
Edge Steepness (worst falling and rising edges)
Additionally to the logical and physical measurements the CANobserver is getting data about bus status, bus traffic load and the optional CAN supply voltage.
The CANobserver fits into the definitions of VDI/VDE guideline 2184. (Preview)
