shown in Figure 2.2 only User Number One, User Number Two, and User Number
Five have access to this restricted parameter. The system may have several more
users, but the three users listed on the screen are the only users that have access to
change a die protection setting. The user must use the arrow keys to position the
cursor on his user name. After placing the cursor on the correct name, the user must
press the SELECT softkey. The SELECT softkey must be pressed even if there is
only one user name displayed.
Step C: The display will show the selected user name and request the user password. The
user must enter the correct password and then depress the ENT key.
Step D: Upon entry of the correct password, the user will be allow access to the restricted
item. the example shown in Figure 2.2, the user will have access to change the die
protection type.
After performing the steps listed above, the user will be logged in to the password system. The user
will have access to all restricted items that have been designated for his access. This access will
remain until the user performs a log out or until the user is automatically logged out.
The user can log out by using the ACC key. This key will directly switch the display to the Quick
Access screen. The LOGOUT soft key legend will appear along the bottom of the screen. If the
operator presses this key, he will log out. He will no longer have access to the restricted items,
unless he repeats steps A through D.
In addition to the manual log out, the system contains an automatic logout. The intent of automatic
log out is to reduce the possibility of users other than the intended user from having access to
restricted items. If there were no provisions for automatic log out and a user forgot to manually log
out, all restricted items to which the user had been designated for access would be available from
the log in time until power was removed from the OmniLink control. This presents the possibility
of users other than the intended user having access to restricted items. Automatic log out is based
upon both time and press strokes. During system configuration automatic Access Timeout
parameters are entered. An automatic access timeout time and automatic access timeout strokes are
entered. The time entered is the amount of time after the last key stroke that will be allowed before
the system will automatically log out the user. For example, if the automatic access timeout is set
to 60 seconds, the user will be logged out 60 seconds after the last key stroke. If the user depresses
a key before the 60 seconds have elapsed, a new 60 second cycle will be started. The number of
strokes that are entered is the number of press strokes after the last key stroke that will be allowed
before the system automatically logs out the user. For example, if the automatic timeout is set to 10
strokes, the user will be logged out when the press completes ten strokes after the last key stroke.
If the user depresses a key before 10 strokes have been completed, a new 10 stroke cycle will be
started.
