CANtouch vs. CAN bus Tester 2, the decision.
CANtouch vs. CAN bus Tester 2, the decision.
>> This item is obsolete with the release of the CAN bus Tester GT3. Our new measuring device combines the properties of the CANtouch and the CAN bus Tester 2 and offers far more extensive analysis properties.
Time and again we ask us the question which of the two measuring devices to choose. This question is actually not so easy to answer, it wants to be well thoughtful. There is already the topic for this topicDevice comparisonIn tabular form, here should something else.Be refined.
The CAN bus Tester 2 (CBT2) is the further development of the CAN bus tester (CBT) and
Even today a sought-after measuring device. But the time has not stopped, the CANtouchhas been further developed on the basis of the CAN-Bus Tester 2.Perhaps the most important innovation is theAbsolute value measurementof the CANtouch, while the CBT2 can only measure differently.Only about theDislocation of a memory oscilloscopecan be shown the potential of individual participants with a CBT2.
The importance of this measurement is still not aware of many system operators and maintenance engineers and the CBT2 conceals any problems.The CANtouch, on the other hand, mediates the current measured values and standard limits in acorresponding graphic. The signals of CAN_H and CAN_L are displayed separately in the physical view of the CANtouch, only the view of the difference signal is possible here.Only via the detour of an external DSO, this view is possible with the CBT2, with which significantly more effort during the measurement. The trigger signal comes in the case of the CBT2.
To with aCbt2Being able to measure at least one laptop is necessary.
Of course, this part of the basic equipment and thus available.
The cabling can still be elaborate and it has been taking quite some time,Before you get to the trade fair.If it is a spatially extended system, the effort will return to the technician at the end of the bus.For this reason, it is often only measured at one measuring point and thus half-heartedly.If a central support is to be able to edit the measurements remotely, the CBT2 has advantages because the software is remotely controllable on the PC.Also in an end acceptance for the production of CAN components, a CBT2 makes more sense, as the PC can store results without detours.
Should be measured quickly and mobile, this isCANtouchAdvantage. Unpack, connect CAN connection and off goes here. No external power, no laptop, no USB cable are required. The oscilloscope can also be left packed, because absolute values the CANtouch can measure directly.The software of the CANtouch has been interlinked with the free CAN-Bus Tester 2 ALV software. Measurement archives and data records of CANtouch are importable directly into the PC software.
There, logs can also be printed there, evaluations of the data traffic and comparisons of measurements subsequently.
Direct remote access to the CANtouch is not possible; but possible the remote access to CBT2 software and measurements imported by CANtouch is possible.
If you need occasional continuous monitoring of your bus physics, then the decision pivots more to CBT2 again. It is then complete with a computer and keep in operation as long as the monitoring should run. Windows crashes during the measurement (should happen), the measurement data is lost. The CANtouch got this feature in August 2017.
It seems more useful for this measurement requirement (the continuous monitoring) instead of CBT2 or CANtouch aCANobserver(ev. Also only temporary) to use @ PROMUC as long asThe monitoring should run.The installation is easy, only CAN and 24V are to be connected. Per network cable can be accessed and the device via network cable can be accessed and the device. You can simply remove the laptop and take with you, the CANobserver works independently.
SummarizingLet's look at different deployment scenarios:
Developmentfrom CAN networks: CBT2
- Control the correctBus construction
- Comparison of signal qualitybetween different cables or line guides
- Very more extensiveProtocol monitor for data analysis with symbolic decoding, CANopen NATand J1939 decoding (even without CBT2 inCANvision)
- Potential differences become NEW whererelevant NAT with an oscilloscope for compliance with the limitscontrolled
- Permanent monitoring viaOnline monitor
End acceptanceof CAN components: CBT2
- Device permanently installed
- Data is stored directly
- Potential differences become NEW whererelevant NAT with an oscilloscope for compliance with the limitscontrolled
End acceptancefrom CAN networks according to customer setup: CANtouch
- Mobile use without laptop
- Control the correctBus construction
- Direct control ofPotential differences
- Storing the acceptedValues and later import into CBT2 software
- Control of data content viaSymbolic decoding
- Data traffic can via traceBe recorded
Troubleshootingin workshops (scenario 1): CBT2
- Device permanently installed,z. B. Part of a measuring car
- Potential problems not tooOnly short line lengths expect
- Protocol monitor toData decoding and ev. Data recording
Troubleshootingin workshops (scenario 2): CANtouch
- Device is not only local,but also mobile usable
- faster control of thePhysical parameters of a bus
- Symbolic decodingAllows customized display of events
- Storing measured values overArchiving possible
Troubleshootingmobile: CANtouch
- Quickly to differentPlaces ready for use
- Potential differences are toExpect, especially in extensive plants
- Data decoding and recordingin protocol monitor
- Quick storage ofMeasurement data and later evaluation on PC possible
Permanent monitoring,Predictive maintenance: CANobserver or CBT2
- CANtouch supports the functionAlso, but with slightly limited functions
- with the CBT2 possible ifAlso associated with effort, only temporary use
- CANobserver with the sameFunctionality (continuous measurement), temporary or permanent
