A3.4.3 STATUS_OPTS
Bit Description
Use Uncertain as Good Causes all inputs (OP_SELECT, IN_n, and DISABLE_n) the status of which is “uncertain,” to
be handled as “good” (NC) status inputs and the others to be handled as ”bad” status inputs.
Uncertain if Man mode When the mode is Man, the status of OUT is interpreted as “uncertain.”
(This does not apply to SELECTED.)

Description / Remarks
1 2 3 4
0 17000 17100 BLOCK_
HEADER
Block
Tag=O/S
TAG: “IS” Information relating to this function block,
such as block tag, DD revision, and
execution time.
1 17001 17101 ST_REV - - 2 2 2 2 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 17102 TAG_DESC Null A universal parameter that stores
comments describing tag information.
3 17003 17103 STRATEGY 1 2 A universal parameter intended for use by
the high-level system to identify function
blocks.
4 17004 17104 ALERT_
KEY
1-255 1 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 17105 MODE_BLK 4 4 A universal parameter representing the
operation status of the IS block. It consists
of the Actual, Target, Permit, and Normal
modes.
6 17006 17106 BLOCK_
ERR
- - 2 2 Indicates the error status relating to the
Input Selector function block.
The bit used by this function block is as
follows: Bit 15: O/S mode.
7 17007 17107 OUT MAN 0 5 5 Block output.
8 17008 17108 OUT_
RANGE
100

11 Set the range of OUT.
9 17009 17109 GRANT_
DENY
0 2 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 17110 STATUS_
OPTS
O/S “Use Uncertain
as good” and
“Uncertain if
Manual” only 0 2 A user-selectable option available for status
handling in the block.

12 17012 17112 IN_2 0 5 5 Input 2
13 17013 17113 IN_3 0 5 5 Input 3
