Description

The ADS.Device is the main element of The Xentara Beckhoff ADS Driver. It possesses its own members, publishes its own attributes and exposes its own task. The required parameters for establishing a connection to the target device are defined as members of the Device's configuration and all the information about the connection status are available through the Device's attributes. The desired variables are defined as the children of this element as well as the polls that the variables belong to.
