BUILT-IN ANALOG OUTPUT BLOCK

BUILT-IN ANALOG OUTPUT BLOCK (AOUT)

The built-in analog output block serves as the data handling block for the built-in
current output circuit. This block is used to output an analog value to the current
output circuit. The output circuit converts the value to a milliampere field signal.
This block determines output scaling, tracking and failure conditions.

Available to the user as block outputs are the result, scaled result, track status, and
the data quality for each of these attributes. Also available is the active and
unacknowledged status of the block diagnostic errors. A functional block diagram
of a built-in analog output block is shown in Figure 2-27a (part 1) and Figure 2-27b
(part 2). The Built-In Analog Output Block edit display, which is used to configure
the block, is shown in Figures 2-28 and 2-29.
