Processing details
• This instruction compares BIN 32-bit data stored in n-point devices starting from the device specified by (S1) with BIN 32-bit
data stored in n-point devices starting from the device specified by a constant and (S2) and then stores the result into the
nth device specified by (D) and up.
• If the comparison condition has been met, the corresponding devices specified by (D) will be turned on.
• If the comparison condition has not been met, the device designated by (D) will be turned OFF.

• The comparison operation is conducted in 32-bit units.
• The constant in the device specified by (S1) can be between -2147483648 and 2147483647 (BIN 32-bit data).
