McQuayAO provides read-write access to a numeric data item in a McQuay device. It is similar to a standard NumericWritable, but with a McQuayAnalogProxyExt. Refer to the section “About writable points” in the User Guide for general details on writable points.

Select a McQuayAO for any numeric read-writable data item in a McQuay device that you also wish to control from Niagara (by invoking an action, and/or by linking to an input). If control from Niagara is not needed, alternatively you can select a McQuayAI proxy point instead.

The McQuayAO is selectable when adding new proxy points using the McQuay Point Manager. It is also available for copy (or drag and drop) from the mcquay palette.
