1.3 Input and Output
Assignment
The first step in setting up a Flexible Combiner is con-
figuring the application's inputs.
The first question that must be answered before input
assignment can begin is "What do I want the Flexible
Combiner to do?" Will it choose the highest value from a
series of temperature sensors? Will it calculate enthalpy
from temperature and humidity sensors? Will it read a set
of proofs and turn an output ON if more than half of them
fail?
When you have determined this, make a note of the
following:
• How many inputs of each type you will need (ana-
log and digital)
• How many outputs of each type you will need (ana-
log and digital)
• The types of analog inputs that will be used (tem-
perature, pressure, etc.)
• For analog outputs, the range of values you want
each output to vary between (0-5V, 0-10V, 1-5V,
etc.)
• For digital outputs, whether you want each output
to be a simple ON/OFF digital output or a one-shot
output.
The next step is to assign all the inputs and outputs to
the numbered input and output slots in the Flexible Com-
biner application.

1.3.1.1 Adding a Flexible Combiner
Application
If you haven't added a Flexible Combiner application
yet, you will need to create it in the E2's Add Application
screen.

1. Press
screen.
2. With the cursor highlighting the Type field, press
 and choose "Flexible Combiner" from the
Look-Up Table. Note: If Flexible Combiner does
not appear in this list, it may be because your E2
is not version 2.20 or higher.
3. Enter the number of Flexible Combiners you
wish to add in the "How many?" field.

4. Press to add the new applications.

5. When the E2 asks "Do you wish to edit the new
applications now?" press
to the first setup screen of the application you
added (or, if you added multiple applications, it
will take you to the first application you added).

Flexible Combiner General Setup

Figure 1-2
- Flexible Combiner General Setup
The first screen of the Flexible Combiner is where you
will set up the general parameters required to further
define the application's functions.
Name
Enter a short description of the Flexible Combiner's
function in the Name field.
Num of AI
Enter the number of analog inputs the Flexible Com-
biner will use in this field.
Num of AO
Enter the number of analog outputs the Flexible Com-
biner will use in this field.
Num of DI
Enter the number of digital inputs the Flexible Com-
biner will use in this field.
Num of DO
Enter the number of digital outputs the Flexible Com-
biner will use in this field.
Show Eq Line 2
Each output in the Flexible Combiner has two lines of
40 characters each that may be used to enter its equation.
Since an equation rarely exceeds 40 characters, it is usu-
ally safe to hide the second line from display to make the
screen easier to read. This will be explained in further
detail in Section 1.4.1; for now, leave this field set to NO.
