the Application Controller to represent the 10K Thermistor value on a BACstat with a LINKnet
device address of 5.
With V3.22 or higher loaded in the Application Controller, AV objects may be created in a similar
fashion to the AI objects, which map to corresponding AV objects in the BACstat. You can then use
these in GCL+ programming as well. With V3.21, mapped AV objects are not supported.
Software & Programming
OBJECTS
The following is a list of predefined objects that reside in the BACstat II products that cannot be
created or deleted. When connected to an MS/TP network, these objects are readily accessible over
the network.

* Names are user settable (to a maximum of 32 characters), and only on outputs when they are controlled remotely (i.e.,
MUXed).
These are the typical objects that may be commanded on the fly by a user or from GCL++, and also include the
Outputs when they are MUXed.
GCL++ Programming
All GCL+ programming for BACstats on a LINKnet network is written in the Application Controller
that the BACstats are connected to, using the mapped objects resident in the Application Controller.
The LCD object is used for display and button handling. The mapped AI objects are used for reading
values. And with at least V3.22 firmware on the Application Controller, the mapped AV objects are
used for outputs, setpoints, and various other settings.
