Appendix B — Configuring and Using the SAP Device Controller
This chain passes events through a low pass filter (to remove false
"disappeared" events), filters out unwanted events using the
EventType filter, bundles events together using the aggregator,
and finally transmits the bundled events to SAP-AII using a Send
data processor.
Data processor chains need not be linear. The theoretical example
below processes tag events from pallets and cases differently.
Pallets can set lights on a light tower while events from cases are
augmented with user data from the tags (using a data enricher).
This example assumes you have a tag data scheme set up so you
can differentiate palettes and cases using the tag data.
