CANtouch vs. CAN bus tester 2, the decision.

>> This article is obsolete with the release of the CAN bus tester GT3. Our new measuring device combines the properties of CANtouch and CAN bus Tester 2 and offers much more extensive analytical properties.

Time and again, we are asked which of the two measuring devices should be chosen. This question is actually not so easy to answer, it wants to be well thought out.
There is already a device comparison in tabular form, and there is something else that is further purified.

Development
The CAN bus tester 2 (CBT2) is the further development of the CAN bus tester (CBT) and
Even today, it is still a sought-after. But time hasn't stopped, the CANtouchhas been further developed on the basis of CAN bus tester 2.Perhaps the most important innovation is theAbsolute measurementCANtouch, while the CBT2 can only measure differently.Only about theRemoval of memory oscilloscopeYou can display the potentials of individual participants with a CBT2.
Many plant operators and maintenance technicians are still unaware of the importance of this measurement and the CBT2 conceals any problems.The CANtouch, on the other hand, mediates the current measured values and standard limits in aCorresponding graphics. . The signals of CAN_H and CAN_L are displayed separately in the physical view of the CANtouch, in CBT2 only the view of the difference signal is possible here.This view with the CBT2 is only possible via the detour of an external DSO, with significantly more effort in measurement setup. In this case, the trigger signal comes from the CBT2.

CAN-Bus-Tester-2-perspective
To with oneCbt2At least one laptop is required to measure.
Of course, this component of the basic equipment and thus exists.
The wiring can still be complex and it takes quite a while before you come to measure.If it is a spatially extended system, the effort comes to the technician again at the end of the bus.For this reason, measurement is then often only at one measuring point and thus half-heartedly.

If central support is to be able to process the measurements remotely, then the CBT2 has advantages, because the software can be controlled remotely on the PC. Even in a final acceptance for the production of CAN components, a CBT2 makes more sense, since the PC can store measurement results without detours.

If to be measured quickly and mobile, this isCANtouchin advantage. Unpack, connect CAN port and go. No external power supply, no laptop, no USB cable are required. The oscilloscope can also be packed, because absolute values can be measured directly by the CANtouch.The software of the CANtouch has been interlinked with the free CAN-Bus Tester 2 software. Measurement archives and data recordings from CANtouch can be imported directly into the PC software. There, logs can also be printed, evaluations of data traffic and comparisons of measurements can be carried out subsequently. Direct remote access to the CANtouch is not possible, but remote access to CBT2 software and measurements imported by CANtouch is possible.
CANobserver
If you need occasional continuous monitoring of your bus physics, the decision turns more to CBT2. It is then completely connected to a computer and kept in operation for as long as the monitoring should run. If Windows crashes during the measurement (if yes occur), the measurement data is lost. The CANtouch received this function in August 2017.
It seems more useful for this measurement requirement (permanent monitoring) instead of CBT2 or CANtouching aCANobserver(evident. It is only temporarily) for as long asThe surveillance should run.Installation is easy, only CAN and 24V can be connected. The web interface can be accessed and configured via network cable. You can then simply remove the laptop and take with you, the CANobserver works independently.



In summary, let's look at different application scenarios:


Development of CAN networks: CBT2
  1. Control of the correct bus construction
  2. Comparisons of the signal quality between different cables or wires of very extensive protocol monitors for data analysis with symbolic decoding, CANopen 🙂 and J1939 decoding (also without CBT2 in theCANvision)
  3. Potential differences are controlled with an oscilloscope for compliance with limits where relevant
  4. Continuous monitoring online monitor

Final acceptance of CAN components: CBT2
  1. Device permanently installed
  2. Data is stored directly
  3. Potential differences are controlled with an oscilloscope for compliance with limits where relevant

Final acceptance of CAN networks after setup at the customer's site: CANtouch
  1. Mobile use without laptop
  2. Control of the correct bus construction
  3. Direct control of potential differences
  4. Storage of the accepted values and later import into CBT2 software
  5. Control of data content by symbolic decoding
  6. Traffic can be recorded by trace

Troubleshooting in workshops (scenario 1): CBT2
  1. Device permanently installed, e.g. B. Component of measuring
  2. Potential problems not to be expected because only short line lengths
  3. Log monitor for data decoding and possibly. Data recording

Troubleshooting in workshops (scenario 2): CANtouch
  1. Device is not only local, but also mobile
  2. Faster control of physical parameters of a bus
  3. symbolic decoding allows adapted display of events
  4. Storage of measured values via archiving possible

Mobile troubleshooting: CANtouch
  1. Quickly ready for use in different locations
  2. Potential differences are to be expected, especially in extensive plants
  3. Data decoding and recording in log monitor
  4. Fast storage of measurement data and subsequent evaluation on the PC possible

Continuous monitoring, predictive maintenance: CANobserver or CBT2
  1. CANtouch also supports the function, but with slightly limited functions
  2. with the CBT2 possible, albeit associated with effort, only temporarily use
  3. CANobserver with the same functionality (continuous measurement), temporarily or permanently
