9Ć1 System Security
9.0 SYSTEM SECURITY
To protect the system against unauthorized online changes being
made from the personal computer, AutoMax incorporates three types
of security: a keyswitch on the rack Power Supply module, a
password, and access levels. Note that access levels need to be
considered only if multiple users will need simultaneous access to the
same rack.
9.1 Keyswitch
The keyswitch on the rack Power Supply module provides security
for online operations such as starting and stopping application tasks
by defining a privilege level for the rack. Only online operations
accessed through the ON_LINE option on the Task Manager menu
are affected by the position of the keyswitch. Saving tasks from the
rack, however, is permitted regardless of the keyswitch position. The
keyswitch has three possible settings: PROTECT", SETUP", and
PROGRAM". The AutoMax Executive software displays the current
position of the keyswitch on the top of the screen while you are
online. See below for a description of the privilege level defined by
each keyswitch position.
9.1.1 PROTECT Position
If the keyswitch is in the PROTECT" position, the user can only
monitor variables and save tasks from the rack. Even if the user
knows the password (see 9.2), he cannot perform any other
operations.
9.1.2 SETUP Position
If the keyswitch is in the SETUP" position, the user can monitor all
variables, and save tasks from the rack only. If the USER knows the
password (see 9.2), he can also modify tunable variables. He cannot
perform any other operations.
9.1.3 PROGRAM Position
If the keyswitch is in the PROGRAM" position, the user can perform
all online operations from the personal computer, i.e., load, save, run,
delete, and stop application tasks, and monitor and tune variables. If,
however, the password (see 9.2) has not been entered previously, or
is not entered when the user is prompted, the privilege level defaults
to that of the PROTECT" position.
