Analog I/O Addressing

The size of the Analog Input Table is defined during configuration. The maximum size is 8192 analog channels (words). Like the discrete Input and Output Tables, the Analog Input Table is divided into sections.

Voted Inputs

non-voted Inputs

The voted analog references are assigned starting at %AI0001. The size of the voted analog input area is determined by the number of voted analog inputs including spares.

Physical input data from analog block groups is located at the end of the Analog Input Table, in the areas labelled A, B, and C above. Each of these areas is equal in length to the number of voted inputs at the beginning of the table.
