S
1
: data source device 1.
S
2
: data source device 2.
This command compares the content of
S
1
and
S
2
. Taking API 224 (LD=) as an
example, this command will be activated when the result of comparison is
"equal," and will not be activated when the result is "unequal."
The LD* can be used while directly connected with the busbar
API No.

When the content of C10 is equal to K200, Y10=On.
When the content of D200 is greater than K-30, and X1=On, Y11=On and remains
in that state.
