Index Register
Index register realizes the convenient address operation for the user. You can modify the I/O
address of the register during the machine operation without modifying the edit screen. When
the index register is selected for the component, the new I/O address of this component = the
value of the index register + the original I/O address of this component.
For example:
(1) Create a project and place 5 Number Input components in it.
The settings of Number Input component NI0 are as in the lower left graphics shown:
The settings of Number Input component NI1 are as in the lower right graphics shown:
The settings of Number Input components NI2 to NI4 are the same as that of NI1, and their
addresses are LW10, LW20 and LW40 respectively.
(2) Perform the offline simulation. When the value of index register is 10, the addresses of NI3
and NI0 are the same.
