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 .

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.

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.
