Application Devices and 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 displayed in a
mouse-over popup dialog when the cursor hovers over the physical device ID (see FIG. 68 on page 64).
Each entry in the table has one of four buttons to the right of the Physical Device D:P:S assignment:
Static Bound
application devices will either be
blank,
or display a
Release
button:
Static Bound application devices that have not yet detected a physical device attached to their associated port have a
blank
button.
Once a physical device is detected and its associated Duet module has been started, a
Release
button is then displayed.
Click
Release
to force 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.
Dynamic application devices that have not been bound to a physical device display a
Bind
button. When this button is
selected, a secondary display appears with a listing of all available unbound physical devices that match the application
device's Device SDK class type.
NOTE:
If a currently bound device needs to be replaced or a Duet Module needs to be swapped out, the device should be
unbound and the new module/driver should then be bound.
The administrator/user can then select one of the available physical devices to bind with the associated application device. When
the
Save
button is selected, the binding is created and a process begins within the target Master to find the appropriate Duet
Module driver. Once a driver is found, the Duet Module is then started and associated with the specified application device (Duet
virtual device). If the
Cancel
button is selected, the binding activity is then aborted.
NOTE:
If the manufacturer device does not support Dynamic Device Discovery (DDD) beaconing, you must use the Add New Device
page to both create and manage those values necessary to add a dynamic physical device. This process is described in detail within
the following section.
Viewing Physical Device Properties
Hold the mouse cursor over the Physical Device -
Device
entry in the table to display detailed device properties for that device, in a
pop-up window (FIG. 68).
