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.
New: CANobserver remote diagnostic system now also adapted for use with mobile devices- Bus systems:
- CAN, CANopen, DeviceNet, SAE J1939
- Baud rates (5 kbit/s ... 1 Mbit/s)
- Monitoring, physical:
- General quality level (0 ... 100 %)
- Disturbance-free voltage range
- Rising and falling edges
- Monitoring, logical:
- Active/passive errors, overload frames, ack. errors
- Continuous monitoring
- Bus status, bus traffic load, CAN supply voltage
- User-friendly browser-based configuration and analysis, control point connection via SNMP
- Email notification (device, status and error notification)
- Maintenance without the need for a host-PC, continuous recording of data up to 10 years
- Real-time monitoring of CAN bus plants
- Plant monitoring according to VDI/VDE2184
