For ME Runtime 3.20 and earlier accounts, security provides a way to restrict access to certain parts of the system. You can limit the users who have access to the system by setting up user accounts and passwords. You can also limit users to specific graphic displays.
If you don’t set up security, anyone can use the system and view all the graphic displays without logging on.
Tip: |
Remote Display Number controls do not use the security code. Remote display changes occur whether or not the logged-in user has security access to a given display. |
By default, all users have unrestricted access to all graphic displays. When you assign a security code to a graphic display, only those users who have access to the display can open it. There are 16 security codes, A through P, and the asterisk symbol (*). The * represents unlimited access.
There are two approaches to setting up security: by inclusion and by exclusion. Security by inclusion restricts access only to specific graphic displays, leaving the rest available to all users. Use this method in situations where most users can have access to most displays. Security by exclusion restricts access for all users, except the system administrator, to only a few specific graphic displays.
