Analog Input Channel Object
The Analog Input Channel Class allows the access to the IO-Data and the Register Data of analog channels of the IPxxxx. At Boot Up the IPxxxx determines the number of analog input channels and creates one instance of the object class for each channel.
Class Code: 103 (67hex)
