Index memory
Index memory realizes the convenient address operation for the user. You can modify the I/O
address of the memory during the machine operation without modifying the edit screen. When
the index memory is selected for the component, the new I/O address of this component = the
value of the index memory + 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 figure shown:
The settings of Number Input component NI1 are as in the lower right figure 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 test. When the value of index memory is 10, the addresses of NI3 and
NI0 are the same.
