Notes on operand usage:
Please refer to the function specifications table for each device in
series for the scope of device usage
 S
 This command compares the content of S
example, if the result of comparison is "equal," this command will be activated;
but it will not be activated when the result is "unequal."
 The FAND* command can directly input floating point numerical values (for
instance: F1.2) to the S
D for use in operations.
 This command can be used while directly connected with the busbar

 When X1=Off, and the floating point number in register D100 (D101) is not equal
to F1.2, Y21=On and remains in that state.
