Programming Section 6-3
6-3-5 Password Protection for User-defined Function Blocks
Passwords can be set for user-defined function block files. The password pro-
tection applies to editing and deleting of user-defined function block files. Ver-
ify, Report, and Print operations are not password protected.
1. Select File – Change Password .
The Change Password Dialog Box will be displayed.
2. Enter the password in the New Password field (up to 16 alphanumeric
characters).
3. Re-enter the password in the Confirm Password field.
4. Click the OK Button.
The program password is now set.
From now on a dialog box requesting the password will be displayed when-
ever
Function Block – Edit is selected from the function block list. Unless the
set password is entered, the screen for creating user-defined function blocks
will not be displayed and the function blocks cannot be edited.
The contents of user-defined function blocks can, however, be browsed. The
program must be password protected to prevent browsing of user-defined
function blocks (refer to
6-3-7 Password Protection for Programs ).
Note It is recommended that passwords be set for user-defined function blocks for
which user tests have been completed so that unintentional changes are not
made after the function block has been allocated in a program.
