: The target operand.
If the point before DEC is not a pulse, it will be automatically decremented by 1 for each scan period
This command generally uses pulse type execution command
The DEC instruction has only one operand and does not affect the zero flag.
The calculated data is an unsigned 16-bit binary number.
D0 will automatically increase by 1 when X0 OFF→ON.
: The device to be moved.
: The number of bits shifted to the right.
Shift the contents of the device pointed to by
to the right by
bits.
The number of operations is an unsigned 16-bit binary number.
This command generally uses pulse-type execution commands. No more than 15 digits can be moved at a time.
When X0 OFF→ON, the 16 bits of D0 move to the right in a group of four bits.
