Display page title and identifying information should be used to communicate the position of a display in a larger information space.
Additional Information:
For example, if display pages are functionally related, their names may be designed to reflect this relationship. Some process control display systems assign a unique numerical or alphanumerical code to each display page. The coding scheme may include prefixes and suffixes to indicate relationships between displays. The prefix identifies the major branch of the menu system (e.g., a major plant system). The suffix indicates the level in the branch. For example, if a four-digit numerical coding scheme is used, the first digit may be used to indicate major branches (e.g., 1000, 2000, 3000), and the second digit to indicate the next lower level of branch (i.e., the second level of branches within the 2000 branch would be 2100, 2200, 2300). This pattern may continue for the remaining digits of the coding scheme.
