Explanation
1.
S
1
: Data source device 1
S
2
: Data source device 2
2. This instruction compares the content in
S
1
and
S
2
. If the result is not “0”, the
continuity of the instruction is enabled. If the result is “0”, the continuity of the
instruction is disabled.
3. OR#
(
#:
&, |, ^) is an operation instruction used on parallel contacts.
API No.

Logical “XOR” operation
Example
When X1 = On and the result of logical AND operation of C0 and C10
≠
0, Y10 = On.
1. M60 will be On, if X2 and M30 are On with one of the following two conditions: 1.
The OR operation result of 32-bit register D10 (D11) and 32-bit register D20(D21)
does not equal to 0. 2. The XOR operation result of 32-bit counter C235 and
32bits register D200 (D201) does not equal 0.
