APPENDIX 3. INPUT SELECTOR (IS) BLOCK
A3.4.2 OUT Processing
OUT is an output parameter used to send the value selected in the IS block to another function block.
The following describes OUT processing.

Value specified by MIN_Good > the number of valid inputs
If there is no valid input
If the input status is “bad” or “uncertain” when the
value of OP_SELECT is anything other than “0” (with
the exception of the case where the “Uncertain as
good” bit in STATUS_OPTS is set)
If the value of OP_SELECT is greater than 8, which is
the maximum number of inputs
If OP_SELECT is enabled
If the value is out of the SELECT_TYPE setting range
when the value of OP_SELECT is “0”
If SELECT_TYPE is “First Good”
If SELECT_TYPE is “MINIMUM”
· The previous value is output. (At startup, the initial value is used).
· Writable (the operator may change the value.)
· The previous value is output.
· Not writable
· Zero
· Not writable
· The value of the selected input is output.
· Not writable
· The previous value is output.
· Not writable
· The value of a valid input with the smallest input number is output.
· Not writable
· The minimum value among the values of the valid inputs is output.
· Not writable
If SELECT_TYPE is “Latched Good”
· The value of a valid input with the smallest input number is output.
· Not writable
If SELECT_TYPE is “MAXIMUM”
· The maximum value among the values of the valid inputs is output.
· Not writable
If SELECT_TYPE is “MIDDLE”
(There is an even multiple number of valid inputs.)
· Because two inputs are positioned in the middle of the values of even multiple
valid inputs, the average of the values of these two inputs is output.
· Not writable
If SELECT_TYPE is “MIDDLE”
(There is an odd multiple number of valid inputs.)
· The value of the input positioned in the middle of the values of odd
multiple valid inputs is output.
· Not writable
If SELECT_TYPE is “AVERAGE”
· The value obtained by dividing the added value of the values of valid
inputs by the number of these inputs is output.
· Not writable
