A shifting region supports empty locations intermixed with occupied locations within the region.
As the item moves through the region, it is moved ahead one region location, rather than moving directly to the end location in the region.
As new items are introduced into the region, current items in the region move ahead one region location; the item at the head location is moved to a Shifting Transition region, which is selected when the shifting region is configured.
An example of a shifting region would be in an automobile factory where empty carriers on the line are counted as empty locations.
Example
|
The region in this example is bounded by sensors and has three region locations. |
|
|
1 |
This carrier will enter the Shifting region to occupy region Location 3. |
|
|
The other locations in the region will shift forward one location. |
|
2 |
This carrier occupies Location 2 and will shift to Location 1 when a new item enters the region. |
