A. OUT_D = Discrete output that signals a selected alarm condition
B. OUT = The block output value and status
The Analog Input (AI) function block processes field device measurements and makes
them available to other function blocks. The output value from the AI block is in
engineering units and contains a status indicating the quality of the measurement. The
measuring device may have several measurements or derived values available in different
channels. Use the channel number to define the variable that the AI block processes.
The AI block supports alarming, signal scaling, signal filtering, signal status calculation,
mode control, and simulation. In Automatic mode, the block’s output parameter (OUT)
reflects the process variable (PV) value and status. In Manual mode, OUT may be set
manually. The Manual mode is reflected on the output status. A discrete output (OUT_D)
is provided to indicate whether a selected alarm condition is active. Alarm detection is
based on the OUT value and user specified alarm limits.
lists the AI block parameters and their units of measure, descriptions, and
index numbers.
