Understanding Station Security
PlantScape Server and Client Configuration Guide 213
If you have configured a Station to use Operator-Based security:
• The Station prompts you to sign on, and you cannot access any Station
functions until you have successfully signed on.
If you have not configured a Station to use Operator-Based security:
• The Station starts at a security level of OPER, but you need to enter a
password if you want to access a higher level of security.
The security levels OPER through MNGR can be assigned to server functions. In
order to use the function, the current security level used to run Station must be
equal to or greater than the security level assigned to the function. For example, a
push button on a display might be assigned a security level of SUPV when a
custom display is built. In order for an operator to use the push button, the
Station security level must be either SUPV or MNGR.
Setting Security Levels for Enabling/Disabling Channels and Hardware
Security levels are also used to define which level of security is required to
enable or disable hardware items.
To set the minimum security level required for enabling or disabling:
1 From the System Configuration Menu display, click Server Wide Settings.
2 Under Enable/Disable Hardware, select the security level you want to set
for this operator function.
When you call up the Channel Status Summary and the Controller Status
Summary display (as described in 6.5 “Enabling and Disabling Channels and
Controllers”) you will not be able to use the Enable checkboxes in these displays
unless you are currently logged on at the security level specified.
Note This enable/disable security level setting applies to every Station in your system.
