: data source device 1.
S
2
: data source device 2.

This command compares the content of
S
1
and
S
2
. Taking "FAND=" as an
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
1
,
S
2
operands, or store floating-point numbers in register
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.
