Dynamic Inventory

Introduction

Dynamic Inventory Mode keeps track of tags in the field and generates TAG_ADD and TAG_REMOVED events.

The logic that generates the TAG_ADD and TAG_REMOVED events can be customized to avoid false events.

Configuration

Select the Sequential system mode. Now select the DYNAMIC_INVENTORY read Mode

The settings for the Read mode can be send in the capture below

Options

• • Read time: the time per antenna

  • Read automatically: when enabled the system will start doing inventory rounds without user intervention

    • Please use it together with the following options

• • Added tag window (m): The sliding time window (in minutes) used to calculate the minimum number of reads of a certain tag to be added to the inventory.

  • Added tag min reads: The minimum number of reads in a time window required to consider a tag to be part of the tracked inventory. When a tag is read, the tag read history for that tag is checked, if the number of reads is Added tag min reads or larger, the tag is added into the tracked inventory, and a TAG_ADD event is generated.

  • Removed tag window (m): The sliding time window (in minutes) used to infer a tag is no longer part of the tracked inventory.

Specific settings

• Location threshold (%): Accuracy threshold of tag location. Very high thresholds may discard tags really located in selected zones

The configuration applies automatically. To persist changes click on the "Save" button on the top.
