You can further add other elements to the screen that will be resized For more information refer to the section Element Properties on page 43 85 Customizing Projects Security The security model employed by Z View is designed for simplicity and expandability The security model defines three concepts Security Levels One of five levels used to describe the security level of a user or of an action Basic Operator Supervisor Engineer or Programmer Each security level implies also access to all security levels beneath it For example access to the Supervisor level also implies access to the Operator and Basic levels Permissions Permission describe the security level needed to perform actions of a specific kind such as writing values to the PLC or editing tables Users Descriptors for individual users each user with his own security level Actions which are associated with a permission are performed only when the current user s security level is high enough For example editing screens is possible only when the current security level is equal to or higher than the security level assigned to the Design permission The current security level can be changed by logging in with a user name and password or out Otherwise the security level matches the default user level which can be changed in the security settings dialog box Security Settings To change security settings select Settings gt S
