Using Lockout to
Hide Pages and Menus
If unintentional changes to parameter settings might
raise safety concerns or lead to downtime, your can
use the lockout feature to make them more secure.
Each of the menus in the Factory Page and each
of the pages, except the Factory Page, has a security
level assigned to it. You can change the read and
write access to these menus and pages by using the
parameters in the Lockout Menu (Factory Page).
Lockout Menu
There are five parameters in the Lockout Menu (Fac-
tory Page):
•
Lock Operations Page
[LoC;o]
sets the security lev-
el for the Operations Page. (default: 2)
Note:
The Home and Setup Page lockout levels are
fixed and cannot be changed.
•
Lock Profiling Page
[LoC;P]
sets the security level
for the Profiling Page. (default: 3)
Password Security Enable
•
[ pas ; e]
will turn on or
off the Password security feature. (default: off)
•
Read Lockout Security
[rLoC]
determines which
pages can be accessed. The user can access the se-
lected level and all lower levels. (default: 5)
•
Set Lockout Security
[SLoC]
determines which pa-
rameters within accessible pages can be written to.
The user can write to the selected level and all
lower levels. (default: 5)
The table below represents the various levels of lock-
out for the Set Lockout Security prompt and the
Read Lockout Security prompt. The Set Lockout has
6 levels (0-5) of security where the Read Lockout has
5 (1-5). Therefore, level "0" applies to Set Lockout
only. "Y" equates to yes (can write/read) where "N"
equates to no (cannot write/read). The colored cells
differentiate one level from the next.
