BLK_DATA

TAG: “TB”

General information about the function block

2001

ST_REV

-

-

The revision level of the static data associated with the

function block. The revision value will be incremented

each time a static parameter value in the block is

changed.

2002

TAG_DESC

“ “

The user description of the intended application of the

block.

2003

STRATEGY

1

The strategy field can be used to identify grouping of

blocks. This data is not checked or processed by the

block

2004

ALERT_KEY

1

The identification number of the plant unit. This

information may be used in the host for sorting alarms,

etc.

2005

MODE_BLK

AUTO

The actual, target, permitted, and normal modes of the

block

2006

BLOCK_ERR

-

This parameter reflects the error status associated with a

block. It is a bit-string, so that multiple errors can be shown.

2007

UPDATE_EVT

-

The alert is generated by any change to the static data.

2008

BLOCK_ALM

-

The block alarm is used for all configuration error,

hardware connection failure or system problems in the

block. The cause of the alert is entered in the subcode

field. The first alert to become active will set Active

status in Status attribute.

2009

TRANSDUCER

A directory that specifies the number and starting

_DIRECTORY

indices of the transducers.

DO

DO

Yokogawa specific Dissolved Oxygen transducer block

2011

XD_ERROR

-

The error code in transducer:

- No failure

- Electronics failure

- I/O failure

- Mechanical failure

2012

COLLECTION

-

A directory that specifies the number, starting indices

_DIRECTORY

and DD item IDs of the data collection in each

transducer within a transducer block.

2013

2018

SAMPLE_CAL

-

0 to 50 ppm

Enter the correct (current) measured value. This value

0 to 1999 ppb

is used to calculate the new sensitivity (slope)

0 to 600 %

2019

ZERO_CURRENT

0

+- ZERO_CURRENT

Directly overwrites the current zero current, which is

_LIMIT (param 2037)

the leak current of the sensor

2020

SENSITIVITY

7.5

1.000 to 1999 nA/ppm

Directly overwrites the sensitivity (slope) of the sensor

2021
