====== Use cases: what the machine actually has to do ======

This namespace indexes AEI Corporation's work by **function** (the job the
control system performs), while [[industries:start|industries:]] indexes the
same work by **who buys it**. A single use case recurs across industries:
condition monitoring is the same signal-processing and networking problem on a
textile spindle, a packaging servo and a pipeline pump.

The depth is not repeated here. Each use-case page is a nav-grade entry point
that points into the protocol, operating-system and signal-processing pages
that carry the engineering:

<code>
industries:<industry>  ->  use-cases:<function>  ->  technology:<protocol>
</code>

===== Use cases =====

  * [[use-cases:motion-control|Motion control]] — coordinated multi-axis drives and the cycle budget they impose.
  * [[use-cases:factory-automation|Factory automation]] — discrete cell and line control.
  * [[use-cases:process-automation|Process automation]] — continuous and batch/recipe control.
  * [[use-cases:condition-monitoring|Condition monitoring]] — vibration and motor-current based machine health.
  * [[use-cases:sensor-maintenance|Sensor maintenance]] — calibration, drift and field replacement.
  * [[use-cases:remote-maintenance|Remote maintenance]] — secure remote access to a shipped machine.
  * [[use-cases:remote-portable|Portability and remote presence]] — battery and intermittent-link operation.
  * [[use-cases:autonomous-vehicle|Autonomous vehicles / AGV]] — guided vehicles and their onboard networks.
  * [[use-cases:oil-gas-ndt|Pipeline inspection / NDT]] — in-line inspection tooling.
  * [[use-cases:mes-erp|ERP and MES integration]] — plant floor to business system.
  * [[use-cases:building-automation|Building automation]] — BACnet, BMS and low-power controllers, including home automation.
  * [[use-cases:yarn-cutting|Yarn cutting and clearing]] — winding-machine electronics and splice control.
  * [[use-cases:yarn-testing|Yarn testing]] — textile laboratory instrument control.

Each page lists the **industries it recurs in** and the search terms it is
indexed under, because most of these cross several: condition monitoring is
one problem on a textile spindle, a packaging servo and a pipeline pump, and
an AGV is the same vehicle whether it runs in a mill or a warehouse.

//All thirteen pages are written (July 2026). Each one states the engineering
constraint that defines the use case, then points into the protocol, operating
system and signal-processing pages that carry the detail.//
