Description
Data output from diagnostic services (for example, ReadDataByLocalIdentifier.vi ) is
usually a byte stream of binary data. If you have a description of the data output (for example,
byte 3 and 4 are engine RPM scaled as .25 *
×
RPM in Motorola representation), you can
use Convert to Phys.vi to extract the physical value from the byte stream by filling an
appropriate type descriptor cluster.
