NOTE: When using password aging and the password expires for a user, the user will be required to change
their password before access to the system is permitted. A user can change their password at any
time (even if aging is not used) by selecting “Password” from the main security menu.
The
Log Off Time Period (minutes) field is a global for all users. The log off time begins once a user logs into
the system. If the user does not perform any actions within the specified time, the system will automatically log
the user out. User actions are defined as any action that requires a process change, i.e., changing a SP,
changing an alarm description, etc. Any field protected by security settings of the MCT are user action fields.
The log off time can be set from 0 to 1440 minutes (24 hours). A value of zero disables the auto log off feature.
NOTE: If a user begins an action such as changing a set point, but does not complete the task and leaves
the numeric keypad shown, the system will log the user out if the log off time elapses. However, since
the keypad is still shown, the set point change can still be completed as the task had already begun.
In this case, if a user then enters a new set point, the audit trail will record the change under the user
that was previously logged in, but since the user was automatically logged out while the keypad was
shown, the user will be required to log in to access the set point again.
7.5 Audit Trail
The audit trail viewer is accessed by selecting “Audit” from the Security menu. It displays all user actions that
affected the system for any given day. Each action recorded to the file includes the date/time it occurred as
well as the user (if logged in) that made the change. If no user is logged in, the user will be listed as “Device
Manager”, which is the default user account for the MCT system.
NOTE: If no actions occurred on a given day, an audit file will not be created for that day.
Each time a user takes an action that affect the operation of the system (changing a set point, start/stop data
logging, changes an alarm set point, etc.), the action is written to a file. Audit trail file names are listed as
MMDDYYYY (where MM = month, DD = day, YYYY = year. The
“Open” file button will display a dialog box
where the user can select any audit file to view.
The send email icon allows the user to send a copy of the currently opened audit trail file to any user
configured in the MCT. When the email
icon is pressed, an “Add Recipients” window will be displayed where
the user can select recipients for the file from any of the email addresses configured under the MCT email
settings. For information on how to add email recipients to the MCT, see the section 9.10 Email.
The
Disk icon next to the send email icon allows the user to save the currently opened data file to a USB
memory device connected to the MCT.
