Analog Input Modules The AI Module Configuration includes: ƒ 50/60 Hz Filtering - This parameter enables the user to configure the module to use 50 or 60 Hz filter on all inputs. ƒ 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. ƒ 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. ƒ 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. ƒ "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. ƒ 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).

Analog Input Modules
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).
