ACM-VLX/VLX/EXP/AXM
For example AV-321 is the input type AV for AI-21 on EXP 0/AXM 0 (the
leading 0 is ignored when displaying the AI instance). AV-3300 is the input type
AV for AI-0 on EXP 3/AXM 3.

Setting up input scaling
(Scaled), corresponding Zero and Range AVs must be set. These same values are
used for a different purpose with pulse inputs (input type AV set to 4). See
"Setting up pulse inputs" on page 56 for more information about pulse inputs.
The present-value of the AI associated with the input results from the raw count
input value (from 0–4095) affected by Zero and Range AVs.
