Analog Input Channel Object
The Analog Input Channel Class allows the access to the IO-Data and the Register Data of each analog channel of the ILxxxx-B520 and the connected extension boxes. At Boot Up the ILxxxx-B520 determines the number of analog input channels and creates one instance of the object class for each channel.
The Analog Input Channel Object Class is Vendor specific and within in the range of the Vendor specific Class Codes.
Class Code: 103 (67hex)
