The CAN-Bus Tester 2 is a universal diagnosis tool for the start up, analysis, monitoring, troubleshooting and service/maintenance of CAN bus systems. Typical problems which occur during the operation of CAN bus systems such as node failures, faults in the communication or complete standstill of the plant, often have their origins in the physical bus characteristics. The CAN-Bus Tester 2 provides an overview of the signal conditions on the bus, which helps you to locate and rectify frequently occurring error causes instantly. During the installation phase of CAN bus plants the integrated wiring test is especially useful. It is possible to check the bus cabling by using different measurement methods and thus the transfer properties are ensured. You can also perform comparing measurements directly on the running plant over its lifetime and thus prevent standstills.
- Bus systems:
- Baud rates (5 kbit/s ... 1 Mbit/s)
- Measuring of the signal conditions:
- General quality level (0 ... 100 %)
- Disturbance-free voltage range, rising and falling edges
- Continuous monitoring
- Bus status, bus traffic load, error frame counter
- User-friendly protocol monitor (CAN, CANopen)
- Online trigger (real-time monitoring of the bus for logical and physical errors)
- Testing of cables (Short-circuits, interruptions, loop resistances, cable length)
- Straightforward application software:
- Management of measurements (measurement types, measuring points, measuring times)
- Comprehensive test record, broad variety of export functions
Fields of Application:
- Commissioning of CAN bus plants
- Wiring test, module check
- Service/maintenance of CAN bus plants
- Troubleshooting and analysis of the bus characteristics
