 S
1
: data source device 1. S
2
: data source device 2.
 This command compares the contents of S
1
and S
2
. Taking "FOR=" as an
example, if the result of comparison is “equal”, this command activates; but it does
not activate when the result is “unequal”.
 The FOR* command can directly input floating point numbers (for instance: F1.2)
to the S
1
, S
2
operands, or store floating point numbers in register D for use in
operations.
 You can use this command directly to connect with the busbar.
