Sensor Transducer Block

The transducer block contains the actual measurement data, including a pressure and temperature
reading. The transducer block includes information about sensor type, engineering units, linearization,
reranging, temperature compensation, and diagnostics.

Read Enabled ADVISE_ALM alarm conditions. Corresponds bit
for bit to the ADVISE_ACTIVE. A bit on means that the
Only
corresponding alarm condition is enabled and will be
detected. A bit off means the corresponding alarm
condition is disabled and will not be detected.
E Mask of ADVISE_ALM. Corresponds bit of bit to
ADVISE_ACTIVE. A bit on means that the condition is
masked out from alarming.
E Read Enumerated list of advisory conditions within a device.
Only
N/A Alarm indicating advisory alarms. These conditions do
not have a direct impact on the process or device
integrity.
None Read Parameter representing the overall health of the device,
100 being perfect and 1 being non-functioning. The
Only
value will be set based on the active PWA alarms in
accordance with the requirements stated in "Device
Alerts and Health Index PlantWeb Implementation
Rules". Each device may implement its own unique
mapping between the PWA parameters and
HEALTH_INDEX although a default mapping will be
available based on the following rules.
HEALTH_INDEX will be set based on the highest priority
PWA *_ACTIVE bit as follows:
FAILED_ACTIVE: 0 to 31 – HEALTH_INDEX = 10
MAINT_ACTIVE: 27 to 31 – HEALTH_INDEX = 20
MAINT_ACTIVE: 22 to 26 – HEALTH_INDEX = 30
MAINT_ACTIVE: 16 to 21 – HEALTH_INDEX = 40
MAINT_ACTIVE: 10 to 15 – HEALTH_INDEX = 50
MAINT_ACTIVE: 5 to 9 – HEALTH_INDEX = 60
MAINT_ACTIVE: 0 to 4 – HEALTH_INDEX = 70
ADVISE_ACTIVE: 16 to 31 – HEALTH_INDEX = 80
ADVISE_ACTIVE: 0 to 15 – HEALTH_INDEX = 90
NONE – HEALTH_INDEX = 100
None Parameter that allows direct writes to PWA active
parameters and the detailed status bytes that activate
the Plant Web alerts. The simulate switch/jumper must
be "ON" before PWA_SIMULATE can be turned on.
0 = Simulation off
1 = Simulation on
The revision level of the static data associated with the
function block.
N/A The user description of the intended application of the
block.
N/A The strategy field can be used to identify grouping of
blocks.
