Setting Project Access Control

For project security, set access control using a password for projects, controllers, program organization units (POUs), libraries, and library functions and function blocks. Password definitions are limited to eight characters and can consist of letters and digits. Enter the password to open a password-protected project. Project sub-elements, can have their own level of access control. Example: a POU with its own password remains locked and cannot be modified without entering its password.
Since POUs are encrypted, password definitions must be retained.
In the
Application View
, the following indicates the security state for elements:
cam_ac Indicates that a lock is applied to the element
When opening a project with password-protected elements, there is a prompt to enter the password once for each element. Password-protected elements have these modification restrictions:
