If only COLLECT FAULT DATA is checked, it will cause the following fault data to be
collected:
MID-Module Identifier of the diagnosing controller
CID-Component Identifier of the fault device
FMI or SubCode-Fault Mode Identifier showing the severity of the fault
Flags-Indicates whether the codes is Event or Diagnostic Code and whether it is
Active or not
If FETCH FAULT DETAILS is also checked, the driver will also collect the following
information for each fault code:
OCCURENCES-Number of times this code has occurred
FIRST-First occurrence in engine operating hours
LAST-Last occurrence in engine operating hours
In figure 7.2 below, you can see a block of fault data collected without Fault Details and
mapped to Allen Bradley Tag Names, as an example. As you can see in this figure:
Faultsource=MID
Faultcode=CID
Faultsubcode=FMI or Sub-Code
FaultFlags=Shows whether it is a Diagnostic Code or Event Code (Bit7) and whether
the code is currently ACTIVE (Bit0).
If Bit7 of this value is high, then it is a Diagnostic code. If low, then it is an Event.
