12.11.1.2 Setup Screens
Figure 12-25
- Example Setup Screen (Setpoints)
When setting up an application using a Setup screen
(see Section 10.7.2, Status Screens ) all inputs and outputs
that are set up to be logged will be marked with an L on
the right-hand side. From the Setup screen, you may
access the logs of these inputs by pressing

.
12.11.1.3 Setting Up Input and Output
Pointers
Figure 12-26
- Pointer Format Box
Pointers allow a property to get or send its value to
another property, and are a way to transfer information or
values (input and outputs) from one application to another
within a controller.
For example, if you are setting up a Suction Pressure
pointer, you are specifying the location of where the Suc-
tion Pressure is coming from. Note that:
• An output pointer can be connected to multiple
input pointers
• A single input pointer cannot be connected to mul-
tiple output pointers
• Pointers can be set up for all applications
To set up pointers from a Setup screen:
1. Press

( SETUP ) from the desired applica-
tion’s Status screen. (If starting from the Home
screen, move the cursor to the desired applica-
tion’s value and press

to open the Actions
Menu. Choose Setup . This will take you to the
Setup screen.)
2. Once inside the application’s Setup screen, use
the

and

keys to highlight the Inputs
and Outputs index tabs.
3. Press

( EDIT ) to open the Edit menu.
4. Choose Alternate I/O Formats to open the for-
mat menu.
5. Choose one of the pointer formats.
If you are in the Inputs setup and have selected Area
Ctrl: Application: Property as the pointer format, the
third column (the Output field) is the output that you are
pointing (connecting) the input to. If you are in the Out-
puts setup and have selected Area Ctrl: Application:
Property as the pointer format, the third column (the
Input field) is the input that you are pointing (connecting)
the output to.
Changing the format to a Fixed Value will give you
the option of entering a value in the field that will be read
by the input instead of being hooked to a board:point or
another cell.

lers, applications, and points, see Section 12.12, Naming
Conventions for E2 Controllers, Applications, and Points .
