Explanation
1.
Only the 32-bit instruction can use HC devices but not E devices. The firmware of V1.04.00 and later for AS300 PLC
supports the instruction.
2.
See the following table about data types that the operands S
_6
represents 'Unusable'.)

16#
F
Note: SM685=ON (the floating point number operation) works for the 32-bit instruction only.
3.
S is the data source. S

exceeds the range, the instruction will be executed automatically at the minimum value or maximum value. S
setting value for comparison in a multi-point area. S
comparison value corresponds to, e.g. the number of areas, S
areas. S ~ S

4.
The comparison order for multi-point areas is 0, 1, 2 ...S
value does not belong to an area, the comparison will move on to the next area. For example, S
S +2, the comparison keeps going until the number of comparison times reaches S
