Note: The Range Source Set Point With Attribute or
Range Source Set Variable With
Attribute function block can be used to store the region and
region location of the selected item to virtual points, or as RCO,
variables that can be referenced by the output logic controlling
how an item moves.
Ranges can be made up of multiple regions or specific locations within those regions. When a dialog box field supports entry of a subset of locations within a range, use the following codes to specify the locations you want:
|
Location |
|
||
|
>0 |
Location that corresponds to the entered value. |
||
|
=-1 |
LAST location in the region. |
||
|
=-2 |
FIRST location in the region. |
||
|
=-3 |
ALL locations in the region. |
||
|
|
StartLocation |
EndLocation |

=-2 |
FIRST location in the region. |

|
=-1 |
>0 |
Currently undefined. This will return an empty set. |
|
|
>0 |
=-1 |
A StartLocation that is >0 to the end of the region. |

>0 |
<n |
Between StartLocation and EndLocation. Note: StartLocation should be less than or equal to the EndLocation. |
