: data source device 2.

This command compares the content of
S
1
and
S
2
. Taking "FOR=" 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 FOR* 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
