5.1-12 Separate Display Pages for Plant Modes

Where plant operating modes impose different demands, separate display pages should be provided for each mode.

Additional Information:
Some typical modes of plant operation are power operation, startup, hot standby, and hot shutdown. For each mode, the displays should contain at least the minimum set of data needed to assess the safety status of the plant. One means for accommodating the plant modes is to have a top-level display that is independent of plant mode and a set of mode-dependent subordinate display pages.
