Information display guidelines for primary stations

Information arrangement

  Arrange the screens according to the expected rate of access to the information:

• All-at-once ... arrangement is suitable for information used frequently (such as control data), enabling fast perception, since the operators have sufficient opportunities to learn the location of the information items on screen
• Drill-down ... arrangement is suitable for information used rarely (such as setup data), enabling safe perception, since the operators are not expected to learn their location on screen.

Redundant information

  Do not present irrelevant information that may take too long to read

Avoid overwhelming data

  Enable the operators to explicitly hide the setup parameters.

  Context-sensitive screens used in routine operation should provide special salient indication about context variables with exceptional values.

Highlight exceptions

  When there are too many parameters to display, highlight those that deviate from the default data
