McQuayBooleanProxyExt is the proxy extension for either a McQuay BI (read-only) proxy point or a McQuay BO (writable) proxy point. Like any McQuayTypeProxyExt, it represents a single piece of data defined by a combination of the register address and the data register length, and has standard proxy extension properties such as Status and Enabled, among others (see “ProxyExt properties” in the Drivers Guide for related details). For additional details, see McQuay proxy points.
