1. CAN-Bus Tester 2 – mobile CAN diagnosis tool

The CAN-Bus Tester is a mobile tool, that is used for physical and logical long-term monitoring of CAN network plants (CAN, CANopen, DeviceNet, SAE J1939).

The CAN-Bus Tester 2 constitutes a universal measuring instrument for the commissioning, analysis, monitoring, troubleshooting and service/maintenance of CAN network plants.

Typical problems which occur during the operation of CAN network plants, 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 without unnecessary delay.

You can already ensure a correct bus cabling and verify its transmission properties when setting up the plant. You can also perform comparing measurements directly on the running plant over its lifetime and thus prevent downtimes.

New licensing model: The CAN-Bus Tester 2 is available as a basic version with the bus system CAN. Optional bus systems (such as DeviceNet) and software modules can be activated via license keys at any time.

Fields of application:

  • Commissioning of CAN network plants (Wiring test, module check)
  • Service/maintenance of CAN network plants
  • Troubleshooting and analysis of the physical bus characteristics
  • Development of CAN modules
  • Final testing in the production

Features

  • Bus systems:
    • CAN, CANopen, DeviceNet, SAE J1939
  • Bit-rates (5 kbit/s to 1 Mbit/s)
  • Measuring of the signal conditions:
    • General quality level (0 % to 100 %)
    • Disturbance-free voltage range
    • Rising and falling edges
    • Oscilloscope with message frame analysis
  • Continuous monitoring
    • Bus status, bus traffic load, error frame counter (active error/passive error)
  • Online trigger (real-time monitoring of the bus for logical and physical errors)
  • User-friendly protocol monitor
  • Testing of cables
    • Short-circuits, interruptions, loop resistances, cable length
  • Straightforward application software:
    • Management of measurements (measurement types, measuring points, measuring imes)
    • Comprehensive test record, broad variety of export functions
    • Automatic evaluation of the measurement results

2. CANobserver – stationary CAN diagnosis tool

The CANobserver is a stationary tool, that is used for physical and logical long-term monitoring of CAN network plants (CAN, CANopen, DeviceNet, SAE J1939).

Once the plant stands still, it is too late in most cases. In order to initiate steps against this, both the components of the plant and the supply network have to be maintained continuously. The operation parameters of the bus system degrades due to wear. Gemac's CANobserver® diagnoses such changes while day-to-day functioning continues and informs the plant operator.

The CANobserver is a diagnosis tool that's used for physical and logical long-term monitoring of CAN network plants. It has been planned as a stationary supplement of the CAN-Bus Tester 2. The CANobserver is implemented into the network permanently and monitors the data transfer continuously. This is the optimal means of safeguarding a future-oriented maintenance.

Fields of application:

  • Real-time monitoring of CAN network plants
  • Plant monitoring according to VDI/VDE 2184

Features:

  • Bus systems:
    • CAN, CANopen, DeviceNet, SAE J1939
  • Bit-rates (5 kbit/s to 1 Mbit/s)
  • Monitoring physical
    • Quality level (0 % to 100 %)
    • Disturbance-free voltage range
    • Rising and falling edges
  • Monitoring logical
    • Active/passive error frames, overload frames, acknowledge errors
  • Continuous monitoring
    • Bus status, bus traffic load, CAN supply voltage
  • User-friendly browser-based configuration and analysis
  • Control point connection via SNMP
  • Cyclical or event-driven e-mail notification
  • Maintenance without PC, continuous recording up to ten years
