1) Functions
- Compares contents of [ S1 ] and [ S2 ], then operates as a parallel NO contact according to the
comparison operation result. The comparison is executed as signed operation.
- The comparison operation result is as shown below :

2) Program example
a) Compare P0000 ~ P000F and D0001. If their values are equal or M000 is on, P0010 bit will be
switched on.
M000
= P000 D0001
b) Compare 1000 and contents of D0001 and D0002 (32 bits). If the content of D0001 and D0002 is less
than 1000 or M020 is on, P0010 will turn on.
