Understanding Station Security
When you define a Station, you also define the security method that will control
access to functions at that Station. In Quick Builder, you choose between:
• Station-Based security
• Operator-Based security
Your choice of security method for each Station determines:
• Whether or not users need to sign on to that Station with a special user ID
and password
• The security level setting used when that Station starts up
• The total number of security levels available to your system
• The tasks you need to carry out to configure Station access
About Station-Based Security
Station-Based security is the default used for Station access. Station-Based security
works as follows:
• Station starts without prompting users to enter any form of user ID or
password.
• The initial security level setting allows users to perform the basic operating
functions associated with the user level of OPER (for example,
acknowledging alarms and controlling points).
• Users only need to use a password if they want to change to a higher level
of security.
• Area assignment applies to the Station, not to the operator.
The security levels and their associated functions are described in “About Security
Levels” on page 212.
About Operator-Based Security
Operator-Based security provides a higher level of security than Station-Based
security. Operator-Based security works as follows:
• You assign a specific security level to each user.
• Users cannot access any Station functions unless they enter a valid ID and
password.
• To access a higher security level than the one they are currently using, users
need to sign off and sign on again as a different operator who has the
higher security level.
