Appendix 3. Input Selector (IS) Block
A3.3 Selection
The following processing is performed after completing input processing. If the number of valid inputs is less than
the value of MIN_Good, no input selection is made.
A3.3.1 OP_SELECT Handling
When a value other than “0” (that is, 1 to 8) is selected for OP_SELECT:
The IS block selects the input of the number specified by OP_SELECT regardless of the setting of SELECT_TYPE,
propagates the value of that input to OUT, and transmits the input number to SELECTED.
IN_1 = 23
SELECT_TYPE = Minimum
STATUS_OPTS
MIN_GOOD = 1
SELECTION
SELECTED = 3
OUT = 45
IN_2 = 34.5
IN_3 = 45
IN_4 = 2.34
IN_5 = 23.6
IN_6 = 15.5
IN_7 = 32.5
IN_8 = 27.4
DISABLE_1 = OFF
DISABLE_2 = OFF
DISABLE_3 = OFF
DISABLE_4 = OFF
DISABLE_5 = OFF
DISABLE_6 = OFF
DISABLE_7 = OFF
DISABLE_8 = OFF
OP_SELECT = 3

Figure A3.3 Example (2)
In the above example, SELECT_TYPE is set to Minimum. However, because OP_SELECT specifies the value and
number of IN_3, the value and number of this specified IN are transmitted to OUT and SELECTED.
* Note: Even if the IN specified by OP_SELECT is an invalid input (the corresponding DISABLE parameter is ON or the IN’s status is “bad”),
the value and status of that IN are transmitted to OUT.
