Trimming-
Each channel of the AIM can be trimmed
with two data points within the selected zero and span
measurement range. Refer to Trimming section of this
manual for more information.
Filter-
This setting is used to configure the input
filter. This filter is designed to reduce the effects of
mains-induced noise. The value should be set to the
frequency of the local AC supply–either 50Hz or 60Hz.
Saving Configuration Settings-
If you will be using
a common configuration within your system, you can
create a configuration and save it to a file so that
you can load it into another I/O module. Refer to the
Saving Configuration Settings
section of this manual
for more information.
Input On Failure-
From here you may select how your
input value reacts upon a failure. Selecting
Hold Last
maintains the value last read before the failure. To
display a user-selected value, click the
Preset
button
and then enter the value into the
Predefined Value
text
box. The unit displayed will depend upon the
Input
Type
that you have chosen (MilliAmps or Volts).
Input Scaling-
Input Scaling allows you to take the
input and convert it to a different range. For example,
you take a channel with a 0-10V range and scale it to
0-100V; now when the input is 7.34V, it is relayed to
the Interface Module as 73.4V.
Custom Curve-
The Custom Curve box allows you
to setup a custom linearization table of up to 128
points that will tell the AIM what value to output when
a certain input is received. Refer to the
Custom Curve
section of this manual for more information.
Configuring the AIM
The AIM can be configured using the web server
contained within the Interface Module to which it is
attached. It can also be configured using the NCS
PC Configuration Software. For further details
please see the
Navigating the PC Program
in the
Configuration Section
of this manual. To configure the
AIM, you must first mount it to the Interface Module as
described in
Installing the I/O Modules
.
To access real-time data using MODBUS commands
instead of the web server, see
the MODBUS/TCP
Support
section in the MODBUS chapter of this
manual.
Note:
The AIM I/O module is set to factory defaults,
to use either method mentioned above to
configure with your desired parameters.
Current Channel-
The AIM accepts four different
analog inputs, and uses a separate channel for each.
Select the channel you wish to program.
Channel Disabled
- Checking this box will cause the
AIM and the associated NCS to ignore the selected
channel, allowing you to use less than all four
channels without receiving error messages.
Tag Name-
Allows you to place an identifying
descriptor (24 alphanumeric characters, maximum) in
the AIM channel being configured.
Note:
Space is an illegal character and will cause
errors. Use an underscore (_) instead of
using a space.
Input Type-
This sets the type of input that the AIM
will receive. Different measurement types require
different parameters to be programmed. When a
measurement type is selected, other parameters may
become red, indicating that the red parameter must be
programmed.
Input Ranging-
Allows you to either input or capture
the upper and lower ranges that you want to have
measured.
