APPENDIX 1. LIST OF PARAMETERS FOR EACH BLOCK OF THE EJA
A1.3 Transducer Block
Relative
Index
Index Explanation Write Mode Factory Default Parameter Name
0 2000 TAG: “TB” Block Header Information on this block such as Block Tag, DD
Revision, Execution Time etc. Block Tag
= O/S
1 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. –
2 2002 (blank) TAG_DESC The user description of the intended application of the
block AUTO
3 2003 1 STRATEGY The strategy field can be used to identify grouping of
blocks. This data is not checked or processed by the
block. AUTO
4 2004 1 ALERT_KEY The identification number of the plant unit. This
information may be used in the host for sorting alarms,
etc. AUTO
5 2005 AUTO MODE_BLK The actual, target, permitted, and normal modes of the
block. AUTO
6 2006 – BLOCK_ERR This parameter reflects the error status associated with
hardware or software components associated with a
block. It is a bit string, so that multiple errors may be
shown. –
7 2007 – UPDATE_EVT This alert is generated by any change to the static data. –
8 2008 – BLOCK_ALM The block alarm is used for all configuration, 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 the Active status in
the Status attribute. –
9 2009 – TRANSDUCER_
DIRECTORY A directory that specifies the number and starting
indices of the transducers. –
10 2010 100 (Standard Pre-
ssure with Calibration) TRANSDUCER_
TYPE Identifies transducer. –
11 2011 – XD_ERROR The error code in transducer.
0=No failure
20=Electronics failure
22=I/O failure
21=Mechanical failure
–
12 2012 – COLLECTION_
DIRECTORY A directory that specifies the number, starting indices,
and DD Item Ids of the data collections in each
transducer within a transducer block. –
13 2013 107: differential
pressure
108: gauge pressure
109: absolute pressure PRIMARY_
VALUE_TYPE The type of measurement represented by primary
value.
Followings are available for EJA:
107=differential pressure
108=gauge pressure
109=absolute pressure
O/S
14 2014 – PRIMARY_
VALUE The measured value and status available to the function
block. –
15 2015 Range of capsule PRIMARY_
VALUE_RANGE The High and Low range limit values, engineering units
code and the number of digits to the right of the decimal
point to be used to display the primary value. –
18 2018 Minimum span of
capsule CAL_MIN_SPAN The minimum calibration span value allowed. –
16 2016 Max range CAL_POINT_HI The highest calibrated value. O/S
17 2017 0 CAL_POINT_LO The lowest calibrated value. O/S
21 2021 Range of capsule SENSOR_RANGE
TA0103-1.EPS
The High and Low range limit values, engineering units
code and the number of digits to the right of the decimal
point for the sensor. –
19 2019 kPa CAL_UNIT The engineering unit for the calibrated values. –
20 2020 Silicon resonant SENSOR_TYPE The type of sensor. –
