Diagnostic Events Reported According to FF-912 Field Diagnostic Profile Specification

FF-912 – Field Diagnostic Profile specification was created recently to enhance and
standardize the device status reporting to the host. It creates a single group of parameters to
aggregate all device status and diagnostics so that a Host system can integrate this
information into its infrastructure.
Figure 94 from the FF Specification illustrates the basic Field Diagnostic.
The SVI FF monitors the specific conditions, as described in "Continuous Diagnostics" on
page 233. These conditions are classified by the corresponding MAPs in four different
categories and indicated in four different parameters:
Fail – FD_FAIL_ACTIVE
Off Spec - FD_OFFSPEC_ACTIVE
Maintenance Required – FD_MAINT_ACTIVE
Check Required – FD_CHECK_ACTIVE.
You can then filter the detected condition (FD_XXX_MASK) and the SVI FF populates the
corresponding alarm.
The standard Field Diagnostics Profile allows diagnostic conditions to be polled or to be
reported as multi-bit alarms if the host system supports that specification.
