: data source device 1. S
2
: data source device 2.
This command performs comparison of the content of S
1
and S
2
; when the result
of comparison is not 0, this command will be activated, but this command will not
be activated when the result of comparison is 0.
The OR# command is an operation command in series with the contact.

^: logical XOR operation.
When X1=On or the content of C0 and C10 is subjected to the logical
AND operation, and the result is not equal to 0, Y0=On.
When X2 and M30 are both equal to On, or the content of 32-bit register D10 (D11)
and 32-bit register D20 (D21) is subjected to the logical OR operation, and the
result is not equal to 0, or the content of the 32-bit counter C235 and the 32-bit
register D200 (D201) is subjected to the logical XOR operation, and the result is
not equal to 0, M60=On.
