What are Application Devices and their association status?
There are two types of application devices: Static Bound application devices and Dynamic
application devices.
 Static Bound application devices specify both a Duet virtual device and its associated
Device SDK class type, as well as a NetLinx physical device port to which the
application device is ALWAYS associated (i.e. statically bound).
 Dynamic application devices specify both the Duet virtual device and its associated
Device SDK with no association to a physical port. Binding of an application device to a
physical device/port occurs at run-time either via auto-binding or manual binding.
Application devices that have a "bound" physical device display their physical device ID within the
Physical Device column. If an associated Duet module has been started to communicate with the
device, its associated property information is then displayed in a mouse-over popup dialog when
the cursor hovers over the physical device ID.
Each entry in the table has one of four values appear within the far right of the Manage Device
Bindings page (FIG. 81).
 Static bound application devices will either be blank or display a Release button.
- Static application devices that have not yet detected a physical device attached to
their associated port are left blank. Once a physical device is detected and
its associated Duet module has been started, a Release button is then displayed.
- By selecting Release, the administrator is forcing the associated Duet module to
be destroyed and the firmware then returns to detecting any physical devices
attached to the port.
 Dynamic application devices either display a Bind or Unbind button.
- Dynamic application devices that have been bound display an Unbind button. When
the user selects Unbind, any associated Duet module is then destroyed and the
"link" between the application device and the physical device is then broken.
