TI_SENS Sensor Blocks (TIS)
The properties column contains the following parameter properties:
■
S: Static (a write access to this parameter increments ST_REV)
■
W: Writeable parameter
■
OOS: Parameter is writeable in out-of-service (OOS) mode only
■
SP: Special (see description column)
■
NF: Non-functional parameter (does not change block behavior)

Description
01
ST_REV
The revision level of the static data associated with
the resource block. The revision value is
incremented each time a static parameter value in
the block is changed.
02
TAG_DESC
The user description of the intended application of
the block.
03
STRATEGY
The strategy field can be used to identify grouping
of blocks. This data is not checked or processed by
the block.
04
ALERT_KEY
The identification number of the plant unit. This
information may be used in the host for sorting
alarms, etc.
05
MODE_BLK
The actual, target, permitted, and normal modes of
the block:
·
■
Actual: The mode the "block is currently in"
■
Target: The mode to "go to"
■
Permitted: Allowed modes that target may take
on
■
Normal: Most common mode for target
06
BLOCK_ERR
This parameter reflects the error status associated
with the hardware or software components
associated with a block. It is a bit string so that
multiple errors may be shown. Supported values
are:
■
Block Configuration Error: Target block mode is
different than OOS and one of the following
conditions is true:
- Sensor type is set to undefined
- "Sensor Range.Unit" is set to a value not
supported by the sensor (e.g., "mV" for a
resistance based sensor)
- User calibration is turned on at "Calibration
Mode", but Calibration State shows no valid
user calibration exists
■
Input Failure: "Primary Value.Status" is BAD, but
not BAD/OOS
■
Out-of-Service: Actual mode of the block is
OOS
07
UPDATE_EVT
This alert is generated by any change to the static
data
