Connecting to an existing CAN bus system in order to measure or monitor communication - but staying neutral and nonreactive in any respect!
A guarantee for absolute transparency of the CAN interface that leaves the bus completely unaffected - that's what is sometimes required by customers for certain applications. No problem for imc BUSDAQ and devices of the imc CRONOS series. The following technical paper explaines, what is behind that issue - mainly three aspects:
- imc device is switched off and may not affect the bus
- imc device has to silently monitor bus traffic without being detected for any bus activity, not even while simply receiving
- galvanical isolation of the CAN interface prevents any loading or electrical degradation of the bus and ensures signal integrity
