Bus, including the RUI. This does not affect field

protocol access.

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

level 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

parameters within accessible pages can be written

to. The user can write to the selected level and all

lower levels. (default: 5)

The table that follows represents the various levels

of lockout 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

simply differentiate one level from the next.

The following examples show how the Lockout Menu

parameters may be used in applications:

1. You can lock out access to the Operations Page

but allow an operator access to the Profile Menu,

by changing the default Profile Page and Opera-

tions Page security levels. Change Lock Opera-

tions Page [LoC;o] to 3 and Lock Profiling Page
[LoC;P]

to 2. If Set Lockout Security [SLoC] is

set to 2 or higher and the Read Lockout Security
[rLoC]

is set to 2, the Profiling Page and Home

Pages can be accessed, and all writable parame-

ters can be written to. Pages with security levels

greater than 2 will be locked out (inaccessible).

2 If Set Lockout Security [SLoC] is set to 0 and

Read Lockout Security [rLoC] is set to 5, all

pages will be accessible, however, changes will

not be allowed on any pages or menus, with one

exception: Set Lockout Security [SLoC] can be

changed to a higher level.

3. The operator wants to read all the menus and not

allow any parameters to be changed.

In the Factory Page, Lockout Menu, set Read

Lockout Security [rLoC] to 5 and Set Lockout

Security [SLoC] to 0.

4. The operator wants to read and write to the

Home Page and Profiling Page, and lock all other

pages and menus.

In the Factory Page, Lockout Menu, set Read

Lockout Security [rLoC] to 2 and Set Lockout

Security [SLoC] to 2.

In the Factory Page, Lockout Menu, set Lock

Operations Page [LoC;O] to 3 and Lock Profiling

Page [LoC;P] to 2.

5. The operator wants to read the Operations

Page, Setup Page, Profiling Page, Diagnostics

Menu, Lock Menu, Calibration Menu and Cus-

tom Menus. The operator also wants to read and

write to the Home Page.

In the Factory Page, Lockout Menu, set Read

Lockout Security [rLoC] to 1 and Set Lockout

Security [SLoC] to 5.

In the Factory Page, Lockout Menu, set Lock

Operations Page [LoC;O] to 2 and Lock Profiling

Page [LoC;P] to 3.

Using Password Security

It is sometimes desirable to apply a higher level of

security to the control where a limited number of

menus are visible and not providing access to others

without a security password. Without the appropri-

ate password those menus will remain inaccessible.

If Password Enabled [pas;e] in the Factory Page

under the [`loC] Menu is set to on, an overriding

Password Security will be in effect. When in effect,

the only Pages that a User without a password has

visibility to are defined in the Locked Access Level
[ loC;L]

prompt. On the other hand, a User with a

password would have visibility restricted by the Read

Lockout Security [rloC]. As an example, with Pass-

word Enabled and the Locked Access Level [loC;L]
