The AI Module Configuration includes:
50/60 Hz Filtering - This parameter enables the user to configure the module to
use 50 or 60 Hz filter on all inputs.
AI Filter (Smoothing) - This parameter enables the user to configure the level
smoothing (averaging) on all inputs. It can be set to 1, 2, 4, 8, 16, 32, 64,128
samples.
Change Of State (COS) Delta - This parameter sets a delta value for each input.
This enables the user application program to get an indication when the input
value change is more than ± delta value.
Input Range - This parameter sets the input overflow and underflow LEDs limits
(refer to AI Module value representation below). In the current input modules, the
ranges that can be selected are: ±20 mA (default) and 4-20 mA. In voltage input
modules, the ranges that can be selected are ± 5V (default), 0-5 V and 1-5 V.
"Keep Last Value" (KLV) and "Predefined Value" (PDV) - Each input can be
configured to KLV or to a PDV. This value is shown to the user application
program in the event of AI module failure. The predefined value can also be used
during normal operation to force a value that masks the actual input value. In this
case the user program will get the PDV instead of the actual input value.
I/O Legacy Resolution Parameter - In systems with both ACE3600 RTUs and
legacy (MOSCAD/MOSCAD-L) RTUs, some MOSCAD/MOSCAD-L
applications can be upgraded to ACE3600 without modifying the references to
analog values in the applications ('C' or ladder). The I/O Legacy Resolution STS
advanced parameter sets the Analog I/O bit resolution to either Actual (ACE3600)
or Legacy (MOSCAD/MOSCAD-L).
