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 alerts
A Failure alert 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 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 four alarm categories. The 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. Software Failure
2. Database Error
3. Auxiliary Device Error
4. Electronics Failure - Main Board
5. Memory Failure - FF I/O Board
6. Internal Communication Failure
7. Electronics Failure - FF I/O Board
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
. 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.
