Table I-1: Resource Transducer Block Parameters (continued)
Parameter Index number Description
TAG_DESC 02 The user description of the intended application of the block.
TEST_RW 08 Read/write test parameter - used only for conformance testing.
UPDATE_EVT 35 This alert is generated by any change to the static data.
WRITE_ALM 40 This alert is generated if the write lock parameter is cleared.
WRITE_LOCK 34 When hardware write protection is selected, WRITE_LOCK becomes an
indicator of the jumper setting and is unavailable for software write
protection.
When software write lock is selected, and WRITE_LOCK is set, no
writings from anywhere else are allowed, except to clear WRITE_LOCK.
Block input will continue to be updated.
WRITE_PRI 39 Priority of the alarm generated by clearing the write lock.
XD_OPTION 44 Indicates which transducer block licensing options are enabled.
I.3 Alerts
The Resource Block will act as a coordinator for alerts. There will be three alarm
parameters (FAILED_ALARM, MAINT_ALARM, and ADVISE_ALARM) which will contain
information regarding some of the device errors which are detected by the transmitter
software. There will be a RECOMMENDED_ACTION parameter which will be used to display
the recommended action text for the highest priority alarm, and a HEALTH_INDEX
parameter (0 - 100) indicating the overall health of the transmitter. FAILED_ALARM will
have the highest priority followed by MAINT_ALARM, and ADVISE_ALARM will be the
lowest priority.
I.3.1
FAILED_ALARMS
A failure alarm indicates a failure 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 FAILED_ALARMS specifically,
they are described below.
FAILED_ENABLED
This parameter contains a list of failures in the device which makes the device non-
operational that will cause an alert to be sent. Below is a list of the failures:
1. Level / Interface Measurement Failure
2. Volume / Temperature Measurement Failure
3. Electronics Failure / Transducer Block
4. Probe Missing
5. Input / Output Failure
6. Non-Volatile Memory Failure
