Function
DBK+
(1) This instruction adds BIN 32-bit data stored in n-point devices starting from the device specified by to BIN 32-bit data
stored in n-point devices starting from the device specified by or a constant. and then stores the operation result into
the nth device specified by and up,
When a device is specified for
When a constant is specified for
(2) Block addition is executed in 32-bit units.
(3) The constant in the device specified by can be between 2147483648 to 2147483647 (BIN 32-bit data).
(4) If the value specified by n is 0, the instruction will be not processed.
(5) The following will happen if an overflow occurs in an operation result:
The carry flag in this case is not turned on.
DBK-
(1) This instruction subtracts BIN 32-bit data stored in the n-point devices starting from the device specified by or a
