Creating a Security Screen 9–3

Security screens use numeric codes to restrict access to any associated

information or processes. For ease of programming, security screens are

provided with default text:

*RESTRICTED ACCESS*

ENTER CODE:

If a different message is required, the security screen text can be edited.

Constructing a security screen usually consists of assigning the security

code(s).

As an operator enters a security code, an asterisk (

) is displayed on the

DTAM for each character input on the keyboard. If a valid security code has

been entered, the next linked screen is displayed. If an invalid security code

is entered, an error message appears. Once the error condition is

acknowledged, the operator can re-enter the code or return to the Main

Menu.
