Explanations:

1. This instruction compares the content in S

and S

. If the result is not “equal”, the continuity of the

instruction is enabled. If the result is “equal”, the continuity of the instruction is disabled.

2. AND

※ (=, >, <, <>, ≦, ≧) instruction is used for direct connection with BUS.

3. If the most left bit of S

and S

(16-bit instruction: b15、32-bit instruction: b31) is “1”, the compare

value will be regarded as the negative value for comparison.

4. When 32-bit counters (C200 ~) are used in this instruction for comparison, make sure to adopt

32-bit instruction (DAND

※). If 16-bit instructions (AND※) is adopted, a “program error” will occur

and the ERROR indicator on the panel will flash and the connecting controller can not run..

Program Example:

1. When X0 = On and the value of C0 is equal to the value of K200, Y10 = On.

2. When X0 = Off and the value of D0 is not equal to -10 and X1 = On, Y11 = On will be retained.

3. When X2 = On and the value of (D11, D10) is lower than 678,493 and M3 = On, M50 = On.
