Incrementing 32-bit binary data
DINC(P)(_U)
These instructions add +1 to the device (32-bit binary data) specified by (d).
■Descriptions, ranges, and data types
■Applicable devices
• These instructions add +1 to the contents of device (32-bit binary data) specified by (d).
• If DINC(P) instruction is executed when contents of device specified by (d) is 2147483647, -2147483648 is stored in the
device specified by (d). (If signed is specified)
• If DINC(P)_U instruction is executed when contents of device specified by (d) is 4294967295, 0 is stored in the device
specified by (d). (If unsigned is specified)
• Flags (zero, carry and borrow) are not activated at this time.
Note that data is incremented in every operation cycle in a continuous operation type instruction.
There is no operation error.
