Title Panel with Some Additional Display Objects

5.3.11.2 Title Panel Alarms Button Recommended

5.3.11.2.1 Although not recommended for new designs, the title panel may also contain an Alarms button that

allows the user to respond to cautions and severe alarms. In this case, the Alarms navigation button in the navigation

panel shall be omitted, and any alarms accessed through a title panel Alarms button shall be displayed in a dialog

box, not as an information panel and its command panel.

5.4 Navigation Panel Mandatory

5.4.1 Navigation buttons shall have a text label. In addition, they may also include an icon to graphically represent

their function. When no icon is present, the button label shall be centered on the button. If an icon is present, the

label shall be centered below the icon. Navigation buttons are arranged horizontally along the bottom of the display,

in the navigation panel, which shall always be present.

5.4.2 Required Navigation Functions Mandatory

5.4.2.1 At a minimum, the user shall always be able to immediately access and respond to alarm and caution

notifications, even when a dialog box is displayed on the current view. Dialog boxes shall not obscure the navigation

panel. Additionally, the user shall always be able to immediately access other parts of the interface if such access is

required to ensure the safe operation of the equipment. Only when prohibited by the operating system or other

implementation limitations such that a displayed dialog box cannot be maintained during, or redisplayed after

navigation, it is allowed that such access may be accomplished by displaying another dialog box that completely

covers the originally displayed dialog box. When the overlaying dialog box is dismissed, the underlying dialog box

is redisplayed, in the same state it was in prior to the invocation of the overlying dialog box (i.e., given the stated

prohibition or limitations, it is not mandatory that access be provided through navigation using the navigation

panel). Immediate access shall mean that the user shall not have to dismiss or otherwise interact with any displayed

dialog box in order to perform the required access. When the user navigates back or otherwise returns from the

required access, the last selected view shall be displayed, along with any dialog box that was displayed, in the same

state it was in. If no dialog box was displayed, the last selected view shall be displayed.

5.4.2.2 An allowed exception is a login and/or logout dialog box or screen if an implementation requires modal

operation while logging in or out.

5.4.3 Conditional Navigation Functions Conditional

5.4.3.1 Except when absolutely prevented by the operating system or implementation limitations, the navigation

panel shall always be available for user selection, even when a dialog box is displayed on the current view. This

makes it possible for the user to directly and immediately access any functional area from anywhere within the user

interface. Immediate access shall mean that the user shall not have to dismiss or otherwise interact with any

displayed dialog box in order to perform the required access. When the user navigates back to a functional area, the

last selected view is displayed, along with any dialog box that was displayed, in the same state it was in.

5.4.3.2 An allowed exception is a login and/or logout dialog box or screen if an implementation requires modal

operation while logging in or out.

5.4.4 Navigation Panel Layout Mandatory

5.4.4.1 The figure below shows the navigation panel, with three buttons labeled “(Future)” indicating the positions

where buttons may be placed if required by the specific implementation of the interface, or as a result of

modifications or enhancements in future releases of the software. It is recommended that the navigation panel

contain no more than ten buttons.

5.4.4.2 The navigation buttons shall be sequenced from left to right in descending order of expected frequency of

use. The most frequently selected navigation button shall be left-most within the navigation panel; and the least

frequently selected button shall be right-most.

5.4.5 Navigation Panel Alarm and Help Buttons Conditional

5.4.5.1 The two exceptions to the above ordering are the Alarms and Help navigation buttons, which, when they are

supported in an implementation, shall be the next to right-most and right-most buttons, respectively. This placement

ensures that the position of these buttons shall remain unchanged, even if subsequent interface modifications or

enhancements require additional buttons. The Alarm button shall be placed so that the spacing between it and

adjacent buttons is larger than the spacing between other buttons, to allow its selection quickly, and without error.

5.4.6 Navigation Button Labels Conditional

5.4.6.1 For each functional area, there is a corresponding navigation button identified by a text label (mandatory)

and icon (recommended) identifying the functionality and information provided. The table below shows text labels

(conditional) for the navigation buttons, a description of each functional area, and some recommended alternative

labels.

5.4.6.2 The top to bottom ordering of the table reflects the left to right ordering of navigation buttons. Also allowed,

but not recommended for new designs, is a left to right ordering of: System, Jobs, Equipment Setup, Recipes,

History, Maintenance, and Configuration. The alternative labels specified in the table may be applied to this

ordering also. Additional buttons, if required for a particular implementation, shall be added between the Setup and

Alarm button positions.

5.4.7 Navigation Panel Saliences Conditional

5.4.7.1 Only one navigation button at a time shall display a pressed appearance. Additionally, navigation buttons

shall display colored salience coding for a number of purposes: 1, to indicate the user is viewing a functional area

(medium blue salience); 2, to indicate an unfinished task (typically an open dialog box) in a functional area not

currently displayed (medium blue salience); and 3, to inform the user that there are new or unacknowledged cautions

or alarms (saturated yellow or saturated red salience, respectively). The caution and alarm saliences are displayed on

the Alarms navigation button only. As an example, if the user has opened a dialog box in the Jobs functional area,

and then selects the Recipes navigation button, the Recipes button shall display a pressed (down) appearance and a

medium blue salience, and the Jobs button shall display an unpressed (up) appearance and a medium blue salience

(Figure 14). This reminds the user that there is an open dialog box in the Jobs functional area. More than one

navigation button may display the unfinished task salience.

5.4.7.2 The Jobs button may also display a medium green salience (not shown) to notify the user that the equipment

is “Ready to Load,” “Ready to Unload,” “Ready to Run,” or is in a similar state such that the user’s attention is

requested in the Jobs functional area. This is useful when the user has navigated to another functional area of the

interface. If there is an unfinished task, its medium blue salience shall remain displayed, even if the user’s attention

is requested.

Navigation Button Saliences

5.4.7.3 The Alarm navigation button, in addition to the medium blue salience, displays a saturated (bright) yellow

salience when there are new or unacknowledged cautions, or displays a saturated red salience when there are new or

unacknowledged alarms. Only the severest level is displayed. That is, when there are both cautions and alarms, the

red alarm salience shall be displayed. When there are no alarms and only cautions, the caution salience shall be

displayed. The figures below show the same situation as Figure 14, with Figure 15 showing a caution salience, and

Figure 16 showing an alarm salience. If there are no cautions or alarms, the Alarm button displays a medium blue

salience if the user is viewing the Alarms functional area, or if there is an unfinished task and another functional area

is being viewed. If a caution or alarm occurs, the medium blue salience is replaced with the appropriate salience, and

is only re-displayed when all cautions and alarms have been acknowledged or cleared.
