4.12.3 Field Diagnostic
Alerts
The Resource Block acts as a coordinator for Field Diagnostic alerts. There
are four alarm parameters (FD_FAIL_ALM, FD_OFFSPEC_ALM,
FD_MAINT_ALM, and FD_CHECK_ALM) which contain information
regarding some of the device errors which are detected by the transmitter
software.
There is a FD_RECOMMEN_ACT parameter which is used to display the
recommended action text for the highest priority alarm. FD_FAIL_ALM has
the highest priority followed by FD_OFFSPEC_ALM, FD_MAINT_ALM, and
FD_CHECK_ALM which has the lowest priority.
Failure Alarms
A Failure alarm indicates a condition within a device that will make the device
or some part of the device non-operational. This implies that the device is in
need of repair and must be fixed immediately. There are five parameters
associated with FD_FAIL_ALM specifically, they are described below.
FD_FAIL_MAP
This parameter contains a list of conditions in the device which makes the
device non-operational that will cause an alarm to be sent. Below is a list
of the conditions with the highest priority first. This priority is not the same
as the FD_FAIL_PRI parameter described below. It is hard coded within
the device and is not user configurable.
1. Electronics Failure - FF I/O Board
2. Internal Communication Failure
3. Electronics Failure - Main Board
4. Memory Failure - FF I/O Board
5. Database Error
6. Software Failure
FD_FAIL_MASK
This parameter will mask any of the failed conditions listed in
FD_FAIL_MAP. A bit on means that the condition is masked out from
alarming and being broadcast to the host through the alarm parameter.
FD_FAIL_PRI
Designates the alarming priority of the FD_FAIL_ALM, see “Alarm Priority”
on page 4-32. The default is 0 and the recommended values are between
8 and 15.
FD_FAIL_ACTIVE
This parameter displays which of the conditions is active.
FD_FAIL_ALM
Alarm indicating a condition within a device which makes the device
non-operational.
