: data source device 1.
S
2
: data source device 2.

This command compares the content of
S
1
and
S
2
. Taking API 240 (OR=) as an
example, when the result of comparison is equal, this command will be activated;
when the result of comparison is unequal, this command will not be activated.

The OR* command is a compare command in parallel with a contact.


When X0=On and the current value of C10 is also equal to K200, Y10=On.

When X1=Off and the content of register D0 is not equal to K-10, Y11=On and
remains in that state.

When X2 =On and the content of the 32-bit register D0 (D11) is less than 678,493,
or M3=On, M50=On.
