43 FD_FAIL_ACTIVE This parameter reflects the error conditions that are being
detected as active as selected for this category. It is a bit string, so
that multiple conditions may be shown.
44 FD_OFFSPEC_ACTIVE
45 FD_MAINT_ACTIVE
46 FD_CHECK_ACTIVE
47 FD_FAIL_MAP This parameter maps conditions to be detected as active for this
alarm category. Thus the same condition may be active in all,
some, or none of the 4 alarm categories.
48 FD_OFFSPEC_MAP
49 FD_MAINT_MAP
50 FD_CHECK_MAP
51 FD_FAIL_MASK This parameter allows the user to suppress any single or multiple
conditions that are active, in this category, from being broadcast to
the host through the alarm parameter. A bit equal to ‘1’ will mask
i.e. inhibit the broadcast of a condition, and a bit equal to ‘0’ will
unmask i.e. allow broadcast of a condition.
52 FD_OFFSPEC_MASK
53 FD_MAINT_MASK
54 FD_CHECK_MASK
55 FD_FAIL_ALM This parameter is used primarily to broadcast a change in the
associated active conditions, which are not masked, for this alarm
category to a Host System.
56 FD_OFFSPEC_ALM
57 FD_MAINT_ALM
58 FD_CHECK_ALM
59 FD_FAIL_PRI This parameter allows the user to specify the priority of this alarm
category.
60 FD_OFFSPEC_PRI
61 FD_MAINT_PRI
62 FD_CHECK_PRI
63 FD_SIMULATE This parameter allows the conditions to be manually supplied when
simulation is enabled. When simulation is disabled both the
diagnostic simulate value and the diagnostic value tracks the
actual conditions. The simulate jumper is required for simulation to
be enabled and while simulation is enabled the recommended
action will show that simulation is active.
Elements: see Table C-2 on page 160 .
64 FD_RECOMMEN_ACT This parameter is a device enumerated summarization of the most
severe condition or conditions detected. The DD help should
describe by enumerated action, what should be done to alleviate
the condition or conditions. 0 is defined as Not Initialized, 1 is
defined as No Action Required, all others defined by manufacturer.
65 FD_EXTENDED_ACTIVE An optional parameter or parameters to allow the user finer detail
on conditions causing an active condition in the FD_*_ACTIVE
parameters.
66 FD_EXTENDED_MAP An optional parameter or parameters to allow the user finer control
on enabling conditions contributing to the conditions in
FD_*_ACTIVE parameters.
67 COMPATIBILITY_REV This parameter is used when replacing field devices. The correct
value of this parameter is the DEV_REV value of the replaced
device.
68 HARDWARE_REVISION Hardware revision.
69 SOFTWARE_REV Software revision of source code with resource block.
