Output
diag ref out is a copy of diag ref in. You can wire it to subsequent
diagnostic VIs.
data out returns the ECU data record. If you know the record data
description, you can use Convert from Phys.vi to interpret this record. You
can obtain the description from the SAE J1979 standard.
success? indicates successful receipt of a positive response message for
this diagnostic service.
error out describes error conditions. If the error in cluster indicated an
error, the error out cluster contains the same information. Otherwise,
error out describes the error status of this VI.
status is TRUE if an error occurred.
code is the error code number identifying an error. A value of 0
means success. A negative value means error: the VI did not
execute the intended operation. A positive value means warning:
the VI executed intended operation, but an informational warning
is returned. For a description of the code, wire the error cluster to
a LabVIEW error-handling VI, such as the Simple Error
Handler.
source identifies the VI where the error occurred.
