that none of the Start or End condition defined in the right-hand dialog is encountered in the
whole record processed by the algorithm. In this case the error message will be "Cannot find
Start and/or End condition on input of CAN2CAN or CAN2Analog."
Another possible cause is that the time frames of the 2 inputs specified do not overlap at all.
The error message will be "No Common Time Span exists between inputs"
Finally, the sequence of occurrence of the Start or End conditions defined in the right-hand
dialog can lead to ambiguous results. (Too many Start conditions for each End condition,
nested Start and End conditions). In this case the message line will show: "Ambiguous
Start/End time relationship for CAN2CAN or CAn2Analog."
Extract CAN Message Data to a Decimal Value
Extract CAN Message Data to a Decimal Value (CANtoValue)
This measurement parameter is used to extract CAN message data in any sequential byte/bit
location and display it as a decimal value that is rescaled to specific operator set units of
measure. Essentially, it allows the conversion of a bit field embedded into a CAN message into a
value with user-definable units.
CANtoValue Measurement Parameter Setup Detail
To access the setup dialog, touch Setup for that parameter in the CAN Measure/Graph Setup
dialog. The Px Parameter dialog box is displayed. On the right side of this dialog box, there is a
setup dialog labeled with the measurement parameter name. Touch the tab with the parameter
name on it, and you will access the following dialog:
