Processing details
■DBK+
• This instruction adds BIN 32-bit data stored in n-point devices starting from the device specified by (S1) to BIN 32-bit data
stored in n-point devices starting from the device specified by (S2) or a constant and then stores the operation result into
the nth device specified by (D) and up.

• Block addition is performed in 32-bit units.
• The constant in the device specified by (S2) can be between -2147483648 to 2147483647 (BIN 32-bit data).
• If the value specified by n is 0, the instruction will be not processed.
