Custom Curve
The Custom Curve feature is applicable to the
following I/O modules: AIM and TIM. It allows you
to create a custom linearization table for non-linear
inputs. This table can then be downloaded to one
or multiple interface modules and saved for backup
purposes.
Custom Curve File
The user can save a Custom Curve in a file, and
then load it into one or more channels using the Web
Server or PC Configuration program.
The web server loads and saves files held in the cfg
folder of the interface module’s file system, whereas
the PC program stores files and accesses files from
the local PC, in user designated locations.
A custom curve file must first be created as a Comma
Separated Value (.csv) file. This can be done using
either Microsoft
®
Excel
®
or other similar spreadsheet
program, (refer to I/O Modules Figure 4) or a text
editor (refer to I/O Modules Figure 5).
1. Open a new sheet in Microsoft Excel ® . Using
column A as your X data, and column B as your
Y data observe the following scheme:
Column A: The X data must be a monotonically
increasing sequence (i.e. each value must be
greater than the previous value in the sequence).
Column B: The Y data may be any sequence.
You may enter up to 128 X,Y pairs. All numbers
must be real, signed numbers, up to 6 digits
long (7 digits and higher must be translated
to exponential notation) or 6 plus one decimal
point. Exponent notation (in the form of 1e+010,
rather than 10e9) may also be used, but it
will be translated to the full value (i.e. 10e9 =
10000000000) and thus must not represent a
number higher than Xe37. Numbers represented
as Xe38 and above will produce errors.
After entering your values, simply save as a .csv file.
2. Observing the same rules, you can also use a
text editor to create your .csv file in the following
manner:
The file must be saved with a .csv extension.
The .csv file is then transferred via “ftp” to the
Interface Module’s cfg directory.
