When a display device can be configured by more than one user, the system should support the coordinated use of the displays.
Additional Information:
Users may modify display pages to address particular task needs or personal preferences. For example, a user may be able to select plant variables to be included in or excluded from the display page, define coding for displayed items, and define axes and scales for plots. When multiple users can manipulate the same displays, coordination may be needed to ensure that they are aware of the current content. In addition, mechanisms are needed to ensure that displays created by one user are not changed or eliminated by other users. Possible solutions include password protection, special directories for storing these displays, and administrative procedures.
