tings and setpoints, and define inputs and outputs in the E2. Figure 10-11shows a typical Setup screen and its pri- mary elements.

Index Tabs:

Figure 12-11- Index Tabs (RX-400 Version Shown)

The 10 boxes at the top of the screen labeled C1 through C0 are known as the index tabs. These tabs pro- vide you with a short index of the screens that are used to set up an application. C1 through C0 represent the screen numbers (C1 being screen 1, C2 being screen 2, and so

on.) Press the key and the number of the index tab (next to the C) and the cursor highlights that index tab.

Each of the Setup screens that you may access will have a name beside its number. In Figure 10-11, for exam- ple, you will notice some tabs have names, while others are blank. This is because there are only four screens in the Setup for this particular application; C3 is not an accessi- ble screen.

There are several reasons why a tab may be inaccessi- ble (i.e., without a name next to the number):

•The tab (and the corresponding screen) is unused and reserved for later revisions.

•The screen may only be accessed when running in Full Options mode (see Section 12.2, Logging On and Access Levels).

•The screen may require one or more fields to be set to certain values before the screen may be accessed. For example, a screen containing nothing but com- pressor proof input definitions might be hidden if there is a field on another screen that tells the sys- tem there are no proof checking devices on the group’s compressors. To access this screen, you would have to set this field to YES.

The screen you are currently in is always highlighted in the screen’s index tab. For example, because Screen 1 is displayed, tab C1 is highlighted.

As you move to other screens within Setup, the high- light will move to different tabs to indicate which screen will be displayed.

Header Icons:
