Analog Output Channel Object
The Analog Output Point Class allows the access to the IO-Data and the Register Data of each analog output channel of the IPxxxx. At Boot Up the Ipxxxx determines the number of analog output channels and creates one instance of the object class for each channel.
Class Code: 104 (68hex)
