Indirect Address
Select this check box to add the value of the address in [Offset Value Address] to the addresses specified in the following. When multiple features are set to a single Switch, the offset is applied to each feature.
Switch Feature tab
[Bit Address] for Bit Switch
[Word Address] for Word Switch
Lamp Feature tab
[Bit Address]
Do not add an offset value to tags set on a device. The offset value is not being added as expected.
If the address is a variable or symbol, you cannot add the offset value across different variables or symbols.
If the address is the element number of an array symbol variable, and the addition of an offset value causes the element number to fall outside the array size range, the switch and lamp will not function correctly. No error is displayed at this time. Set the offset value to fall within the array size range.
This feature is not applied to [Add Data] - [Addition Base Word Address] nor to [Subtract Data] - [Subtraction Base Word Address].
This feature is not applied to the addresses specified for a Special Switch or Selector Switch.
