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
