Write Description
0 17000 BLOCK_
HEADER
TAG: “IS” O/S Information relating to this function block, such as
block tag, DD revision, and execution time.
1 17001 ST_REV — — Indicates the revision level of the set parameters
associated with the IS block. If a setting is modified,
this revision is updated. It is used to check for
parameter changes, etc.
2 17002 TAG_DESC Null A universal parameter that stores comments
describing tag information
3 17003 STRATEGY 1 A universal parameter intended for use by the high-
level system to identify function blocks.
4 17004 ALERT_
KEY
1-255 1 Key information used to identify the location where an
alert has occurred. Generally, this parameter is used
by the high-level system to identify specific areas in a
plant that are under the control of specific operators,
to distinguish necessary alarms only. This is one of
the universal parameters.
5 17005 MODE_BLK A universal parameter representing the operation
status of the IS block. It consists of the actual, target,
permit, and normal modes.
6 17006 BLOCK_
ERR
— — Indicates the error status relating to the IS function
block. The bit used by this function block is as follows;
Bit 15: O/S mode
7 17007 OUT 0 MAN Block output
8 17008 OUT_
RANGE
Set the range of OUT
9 17009 GRANT_
DENY
0 The parameter used to check if various operations
have been executed. The bits in the GRANT
parameter corresponding to various operations
are set before any of them are executed. After the
operations are complete, the DENY parameter is
checked to find out if any bit corresponding to the
relevant operation has been set. If no bit is set, it
is evident that the operations have been executed
successfully.
10 17010 STATUS_
OPTS
“Use
Uncertain as
good” and
“Uncertain if
Manual” only
0 O/S A user-selectable option available for status handling
in the block.
11 17011 IN_1 0 Input 1
12 17012 IN_2 0 Input 2
13 17013 IN_3 0 Input 3
14 17014 IN_4 0 Input 4
15 17015 DISABLE_1 0, 1 0 Selector switch to disable input 1 from being selected
16 17016 DISABLE_2 0, 1 0 Selector switch to disable input 2 from being selected
17 17017 DISABLE_3 0, 1 0 Selector switch to disable input 3 from being selected
18 17018 DISABLE_4 0, 1 0 Selector switch to disable input 4 from being selected
19 17019 SELECT_
TYPE
1-6 0 Specifies the input selection algorithm
20 17020 MIN_GOOD 0-8 0 Parameter specifying the minimum required number
of inputs with “good” status. If the number of inputs
with “good” status is less than the value of MIN_
GOOD, input selection is canceled.
21 17021 SELECTED 0-8 0 Indicates the number of the selected input. However,
it indicates the number of inputs used to calculate the
average it SELECT_TYPE=Average. If no input is
selectable or if there are multiple inputs, it became “0”
(none).
