 This command compares the content of S
if the result of comparison is "equal," this command will be activated; but it will not
be activated when the result is "unequal."
 The FLD* 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
API No.

 When the floating point number of register D200 (D201) is less than or equal to
F1.2, and X1 activated, contact Y21 will be activated and remain in that state.
