50 Controller Memory and File TypesAccess the Static File Protect feature using RSLogix 500/RSLogix Microprogramming software. For each data file you want protected, select theStatic protection in the Data File Properties screen as shown in thisillustration. To access this screen, right mouse click on the desired datafile.Password ProtectionMicroLogix controllers have a built-in security system, based on numericpasswords. Controller passwords consist of up to 10 digits (0-9). Eachcontroller program may contain two passwords, the Password and theMaster Password.Passwords restrict access to the controller. The Master Password takesprecedence over the Password. The idea is that all controllers in a projectwould have different Passwords, but the same Master Password, allowingaccess to all controllers for supervisory or maintenance purposes.You can establish, change, or delete a password by using the ControllerProperties dialog box. It is not necessary to use passwords, but if used, amaster password is ignored unless a password is also used.Publication 1766-RM001A-EN-P - October 2008
