9.2 Password and Access Levels
The password provides an additional level of security for the rack if
the keyswitch on the power supply is kept in the PROGRAM"
position. Any online operations beyond what is allowed in the
SETUP" mode of the keyswitch will require the user to enter the
password first. The password will timeĆout after 2 minutes.
Up to four users can access passwordĆprotected features in an
AutoMax rack via the AutoMax network. See section 12.5 for how to
connect to a rack over the network. In order to prevent conflicts,
users will be granted one of the following access levels when they go
online.
None Ć This level provides the user with monitoring capability only.
The correct password has not been entered by the user.
Data Access Ć This level provides the user with the ability to
Set/Tune/Force only common or I/O variables. Data Access will not
be granted when another user has Rack Access. All users connected
to a rack may have Data Access. It is the responsibility of all users to
coordinate the effect of setting, tuning, or forcing on common
variables and other areas of conflict.
Task Access
Ć This level provides the user with the capabilities of
Data Access plus the ability to Run/Stop/Delete/Load a task and to
modify the local variables in the task using the Set/Tune/Force
functions. If the user has Task access to all the tasks in a rack, he can
Run/Stop/Delete/Load ALL tasks. Other network users trying to
access the task will be denied access and will be shown the
username of the user with privileged access. A user may have access
to one or more tasks as long as no other user has access to those
tasks and no other user has Rack Access.
Rack Access
Ć This level gives the user complete control of all tasks
in the rack. A user with this access level can Run/Stop/Delete/Load
ALL tasks. Rack Access will not be granted if any other user has
Data, Task, or Rack Access.
Users may set their level of access by using the Set Access function
from the Connect menu (see 12.2). A specific level of access will be
granted (if possible) when the user executes a function which
requires that level of access. For example, if a user had previously
entered the password and then attempts to force a local variable,
Task Access will be granted to the user for the task containing the
local data if no other user has access that task. Table 9.1 lists the
access levels required to access passwordĆprotected features.
Data Access will be granted when the user first enters the password.
The user will then be given the opportunity to acquire Rack Access.
This will prevent other users from accessing the protected features in
the rack. If another user has already reserved the rack, a message
will be displayed on the user's workstation that identifies the other
users connected to the rack and their access levels. The user can
also display a list of all other users currently logged onto the rack
with their associated access levels (see 12.6).
