 S
1
: data source device 1. S
2
: data source device 2.
 This command compares the contents of S
1
and S
2
. Taking API 240 (OR=) as an
example, when the result of comparison is “equal”, this command activates; when
the result of comparison is “unequal”, this command does not activate.
 The OR* command is a comparison command in parallel with a contact.

 When X1 = ON, or the current value of C10 is less than / equal to 200, then Y0 =
ON.
 When X2 = ON and M30 = ON, or the content of the 32-bit register D100 (D101)
is more than / equal to 100000, then M60 = ON.
